Impression 2 

A Major Upgrade for the Leading Archimedes 
Document Processing and DTP program 



Computer Concepts' Impression will 
shortly be upgraded to version 2, further 
strengthening its position as market 
leader for document processing and page 
make-up on the Archimedes. 

Exceeding the promise made to ver- 
sion 1 purchasers to provide a free 
upgrade to version 1.1, a free upgrade to 
the Impression 2 program will be sup- 
plied to all registered owners. 

Among the new features provided by 
Impression 2 is the ability to rotate 
graphics instantly. No other Archimedes 
DTP program offers this feature, and it 
will be extremely difficult to match in 
terms of sheer speed. "Rotating Draw files is 



relatively trivial," said Charles Moir, 
Managing Director of Computer 
Concepts, "but fast rotation of sprites such as 
those produced by scanners is a different matter 
altogether. A sample sprite rotation which takes 
over ten minutes in '.Paint happens instantly in 
Impression 2." 

Other important new features include 
the ability to select and move multiple 
text and graphics frames, and a shortcut 
way to define styles. These facilities alone 
will greatly increase productivity. 

"We hope to launch at the Acorn User show, 
but the priority is to ensure that the program is 
tested and reliable" said Moir.

LaserDirect 

The powerful laser that won't burn a hole in 
your pocket! 



A good laser printer is an essential ele- 
ment in achieving good quality desktop 
published documents. 

The Computer Concepts LaserDirect 
system offers the best all-round printer 
available for the Archimedes, and of 




course you can be sure that it is totally 
compatible with Impression. 

LaserDirect is based on the popular 
Qume mechanism, renowned for its 
reliability, offering excellent 300dpi print 
quality and an extremely compact desk 
top size - just 42cm x 42cm base area. 

The package has been designed speci- 
fically for the Archimedes and includes 
the laser printer itself, a custom made 
interface and driver software. All this 
comes in a complete package, ready to 
plug-in and run, for £999 + VAT. 

The LaserDirect driver software has 
been specially developed after research 
and development into PostScript and the

Comment ! 

How does the price of an 
Archi system compare with a 
similar Mac system? Charles 
Moir takes a look... 




The Apple Macintosh created the DTP 
revolution and is still leading the matur- 
ing market today. But while the Mac is an 
excellent system for top-end professional 
publishing including full colour work, 
systems and software sell for prices which 
would make your bank manager quake in 
his boots. 

Colour publishing is developing fast 
on Mac systems - no longer do you have 
to spend £250,000; you can make a start in 
colour publishing with the Mac for only 
about £100,000!! 

The point is that colour accounts for 
only a small part of a much larger pub- 
lishing market; even today the majority of 
publishing is still in black and white. For 
users whose requirement lies here, the 
Archimedes offers an ideal solution. 

Since most of you will already be 
using an Archimedes and Impression 
there's no need to persuade you of the 
benefits. However, it's interesting to make 
a comparison between the current market 
leader (Macintosh) and a similar Archi- 
medes system. I always knew that Mac 
systems were expensive, but even I was 
surprised at just how much more a system 
costs. 

In creating the price table (above- 
right) I have tried to be as fair as possible. 
Each is a complete black and white pub- 
lishing system including computer, 
software, scanner and laser printer. 

The conclusion is that for black and 
white publishing, the Mac system costs 
over £10,000 while a comparable Archi- 
medes system costs under £5,000. 

You have only to attend a Mac User 
show to find out that pricing attitudes are 
quite different in the Macintosh market. 
There are three main publishing packages 
available for the Mac - QuarkXPress, 
PageMaker and Design Studio. These 
packages retail at £695 for the first two 
and £795 for Design Studio! Can you 
imagine the reaction if we announced that 
Impression was to cost £695? I don't think 
we'd be crushed in the stampede. 

This pricing attitude is carried over to 
all add-ons. Laser printers regularly cost 
in excess of £3,000 and grey scale scanners 
(for photographs) start at around £1,300. 
A really low-cost utility is something that 
costs less than £100! 

As you can see from this issue of the 
Archimedean, produced entirely with 
Impression, when it comes to black and 
white or two colour publishing, we can 
produce results every bit as good as those 
from the Mac. 




A complete Archimedes DTP system costs less than half the price of a similar Mac system

associated outline font drawing routines. 
The FastText system used by LaserDirect 
employs optimised text printing routines 
which offer several major advantages 
over the standard Acorn equivalents used 
by other manufacturers. 

FastText converts from font outlines 
to the printed characters very much faster 
than the Acorn routines, resulting in an 
average speed increase of approximately 
100%, as shown in the graph below-right 
for three sample documents. 

But perhaps the most surprising 
aspect of FastText is that it offers this 
huge speed increase without increased 
memory requirements - quite the contrary 
in fact. FastText operates more efficiently 
and actually requires less memory than 
when using the Acorn routines. Sceptical 
users may be interested to know that you 
can use LaserDirect with the standard 
Acorn font drawing software at any time, 
so you can test the speed and capability 
differences for yourself! Why not ask your 
dealer to print one of your files through 
the different systems for comparison? 



LaserDirect Hi-Res 

Computer Concepts are currently work- 
ing on the LaserDirect Hi-Res system for 
Canon LPB4 laser printers. This will be a 
high performance interface card, driving 
the new Canon 4 page per minute laser at 
a staggering 600dpi resolution.

Further details and printed samples are 
available upon request direct from Com- 
puter Concepts.

aspects of RISC-OS 

• Extensive image-enhancement 

facilities, including : brightness 
and contrast controls, 
instantaneous rotation, anti- 
aliasing and graphical grey-map 
control 

• Dual window view, showing 

original image and modified

• Operates both on scanned 

images and on sprite files from 
any source 



Free upgrade to all registered 
owners of Scan-light 

Registered users please call us for your free 
upgrade. If you have not yet registered, please 
send us your registration card or other proof 

of purchase, together with your request for 
a free upgrade 



As faithful followers may recall, 
the original Scan-Light package 
was conceived in the days of old, 
at a time when Arthur ruled the kingdom. 
But Arthur soon grew old and was duly 
replaced by RISC-OS, bringing times of 
abundant software and prosperity for all 
(except Acorn shareholders). 

Although it has undergone some 
minor revisions to add an amount of 
RISC-OS compatibility, it remains 
substantially the same as the original. 

Revised software for the improved 
Scan-Light Plus package is nearing 
completion as this newsletter goes to 
press. It is now fully RISC-OS compatible 
for consistency with other Archimedes 
software. However, it has improvements 
far more significant than this, providing 
image enhancement facilities unrivalled 
in the Archimedes world. 

Images can come from several 
different sources: scanners, digitisers, 
paint programs, etc. and Scan-Light Plus 
is designed to cope with them all. It can 
even support different types of scanners 
with minimal problems of interfacing. 
Advanced sampling techniques allow 
images to be converted from one set of 
grey-scales to another. By converting 



Acorn User Show 

See us at the BBC Acorn User Show 



The most important show this year for 
Archimedes users will undoubtedly be 
the BBC Acorn User Show, to be held in 
September. As always, it looks set to be 
the major launch venue for new products 
from a range of vendors. 

At Computer Concepts we have been 
working for many months to complete 
Impression 2 for its major debut at the 
Acorn User Show. If at all possible, we 
will have finished product on sale, and 
even hope to be giving away free software 
upgrades to registered Impression 
owners. Bring along a note of your serial 
number and, all being well, you can take 
away your upgrade. 

Other products will be on display in 
their current stages of development. 
We're working on a range of products, all 
of which will be on demonstration at the 
show. Now's your chance to see all of 
them together in operation, and to 
compare them with offerings from other 
manufacturers. 

Our technical support staff and 
programmers will be available on the 



stand to demonstrate products and 
answer your questions. Sorry, but there'll 
be no scantily clad ladies handing out 
leaflets - you'll have to go to the Motor 
Show for that!

spare resolution capacity, images can be 
changed to higher numbers of grey-levels, 
e.g. from 16 levels to a 256 level picture. 

The new software operates with two 
main windows, one showing the original 
image and the other showing the image 
interactively as it is modified. In all cases, 
the original is retained, so changes are 
only saved when you're satisfied. 

One of the main problems with 
scanned or digitised images centres 
around contrast and brightness. 
Consequently, one of the best features of 
Scan-Light Plus is its ability to adjust 
contrast and brightness, using an 
interactive grey-map edit tool. This 
enables fine control of all intensities 
within an image, according to the number 
of grey-shades present. Special effects 
such as negatives and posterising can also 
be achieved. 

No compromise has been made over 
speed of operation; the program is written 
in ARM Assembly language, and you 
can't go faster than that. Image rotation 
benefits particularly from the speed 
advantage. IPaint is one of the few 
programs which can rotate images, but it 
makes watching grass grow seem 
positively exciting! As an example, we 
rotated the 160K screen image pictured 
above by a simple 90 degrees. This took 
Paint an astonishing 12 minutes, 
compared with under a second taken by 
Scan-Light Plus. 

The effects of cumulative distortion to 
images can be very destructive. When 
rotating an image by an amount other 
than 90 degrees the pixels are modified. If 
you rotate it back to its original angle, it 
will have become distorted in the process. 
However, Scan-Light Plus always acts 
upon the original image, so no cumulative 
errors can occur, no matter how many 
rotations you apply to the same image. 

Scan-Light Junior retails at £189 + VAT 
Scan-Light A4 retails at £399 + VAT

Ever since the first version of Impression 
we have been working to improve exist- 
ing facilities and to add new ones. When 
we first released Impression we hoped 
that we had produced a bug-free program 
with all the features necessary at the 
targeted level. That's what we hoped - but 
after being nearly ten years in the busi- 
ness we knew the inevitability of bugs 
and the need for new features ! 

So we made a promise to provide a 
free upgrade to version 1.1, intended as a 
relatively minor upgrade, just to ensure 
that after the first few months of use, any 
bugs which had appeared would be fixed, 
and any new features which were desper- 
ately needed could be added. However, 
we should have remembered how dif- 
ficult it is to stop adding features once we 
start. The upshot of this is that bug-fixes 
were implemented and released 
piecemeal, ending at the current 1.07, 
which is really what we intended as the 
promised version 1.1 

Rather than honour a promise to 
provide a 1.1 upgrade, we are instead 
offering to upgrade every registered user 
to version 2 software. This goes far 
beyond our promise, providing a large 
range of advanced new features. 

There are so many enhancements and 
new features that we can't possibly 
describe them all here. Of course if you 
already have Impression, you'll see all the 
features when you get your free upgrade. 
We expect Impression 2 and your free 
upgrades to be available to registered 
customers quoting a serial number at the 
Acorn User Show, but please check avail- 
ability before you come specially! 

Upgrading to Impression 2 

The free software upgrade can be 
supplied to any registered owner of 
Impression. This free upgrade consists of 
a disc and notes detailing the differences. 
However, full packages of Impression 2 
will contain additional fonts which were 
not included with the original Impression, 
but the price of Impression 2 will rise to 
£169 + VAT. As a special offer, for just £20 
+ VAT registered users can obtain an 
extended upgrade containing:- 

• A new manual to fit the existing 

ring binder 

• The new Pembroke font, 

including regular, italic, bold 
and bold italic variations, PLUS 
a new Dingbats font 

• Outline compatible system fonts 

• New Clip art and updated utilities 



You can obtain a free upgrade if you are 
registered on our database simply by 
phoning and quoting your name and 
Impression serial number. Alternatively, 
quote a credit card number or send a 
cheque for £20 + VAT if you would like 
the complete upgrade including manual 
and fonts. 

If you are not registered, please com- 
plete your registration card and return it 
to us. If you have lost your registration 
card, just send us proof of purchase and a 
note of the serial number, name and 
address, together with the order. Remem- 
ber, only registered users are entitled to 
benefits beyond those guaranteed by your 
statutory rights, such as upgrades, techni- 
cal advice and, not to be forgotten, free 
issues of The Archimedean. 

We plan to make upgrades available 
from our stand at the Acorn User Show, 
subject to successful completion within 
the available time. If you intend to visit 
only to collect an upgrade, please check 
availability first - we'd hate you to be 
disappointed! Upgrade priority at the 
show will be to users who are already 
registered on our database. 

Impression 2 Features 

First, a few words of caution. As features 
are added to a program, it gets bigger. 
Impression 2 is therefore larger and 
requires more memory than the previous 
version, although still considerably less 
than any of its competitors. It is possible 
that some documents which loaded in the 
original version may be too large to load 
with Impression 2. 

At this stage the increased memory 
requirement is not terribly severe, but we 
would like to take this opportunity to 
warn that requirements will continue to 
rise in the future. All software suppliers 
enhance their programs and they will all 
require more memory as time goes on. 
Increasing your range of fonts and utili- 
ties will also exacerbate the problem. 

Compatibility 

Documents created in previous versions 
can be loaded straight into Impression 2, 
retaining the complete layout. However, 
as is usual for major upgrades, files saved 
cannot be loaded into earlier versions. 

Multiple frame selection 

One of the most significant enhancements 
is the ability to select and operate upon 
several frames at the same time. Just select 
the first frame as usual, then Shift-click on 
others. You can then drag, cut, copy or 
paste the entire set of frames in one action. 



1 




Multiple selection will greatly increase 
productivity, allowing whole sets of 
related text and graphics frames to be 
moved from one position to another, and 
even from document to document by 
copying and pasting. 

Grouping of frames 

A selection of multiple frames can now be 
grouped such that it is treated as a single 
item. Drag, cut, copy and paste operations 
will be applied to the whole group. 

Grouping has many uses, primarily 
allowing related items to remain together. 
Grouping a large headline with the 
columns of text to which it relates permits 
the whole story to be moved as one unit. 

Effects menu 

Although the style system in Impression 
is uniquely powerful, especially for long 
documents, there are times when it can be 
unnecessarily tedious to define styles for 
'one-off cases. 

As the Impression manual says, it is 
poor design to have a document contain- 
ing many different type designs and sizes. 
Indeed the Impression style system delib- 
erately encourages the use of a consistent 
set of styles throughout a document. 

Impression 2 provides a shortcut to 
style definition, in the form of a com- 
pletely new Effects menu. This lets any 
text effect be applied to any region of text 
directly, without having to define a style. 
For example it is possible to select a word 
and set it to 24pt size, or to any particular 
font directly. 

Since implementing the effects menu 
we have made it easier for users to make a 
mess of the document. It is now very easy 
to use lots of different effects all over the 
document and only realise later that this 
was probably a mistake, and that a style 
would have been better. With this in mind 
we have made it possible for effects to be 
changed into styles. 

Instant rotation of graphics 

Fast rotation of graphics, originally part of 
the development work on Scan-Light 
Plus, is incorporated in Impression 2. Not 
only does it rotate Draw and Sprite files, 
instantly, but it also uses a screen dither- 
ing technique to enhance display quality. 
It is now possible to see grey-level and 
colour sprites in monochrome modes and 
to obtain near -perfect smooth shading in 
colour screen modes. For example, 16 
colour screen modes can now represent 61 
grey-levels. Rotation in Impression 2 is so 
fast that you can point and drag to rotate 
in real time. 




New repeating frame type 

A new type of frame has been imple- 
mented specifically for items which need 
to be repeated on two or more pages, such 
as headers and footers. A frame can be 
created on any page and will automati- 
cally appear in the same position on 
following pages. 

Local rulers 

Just as Effects have been provided as a 
means to quick style changes without 
defining styles, so too have local rulers 
been provided to avoid the need to define 
a style for one-off use. Any area can be 
selected and new ruler settings applied. 
This makes it much easier to include 
occasional tables of figures and the like. 

Hierarchical font menus 

As it becomes more usual to have a large 
number of fonts, the length of the font 
menu is also getting far too long. In readi- 
ness for even greater numbers of fonts, we 
now use hierarchical font menus. This 
lists only one name for a font family in the 
main menu list, with a sub-menu listing 
the variations. So for example, Pembroke 
would be listed in the main menu, but the 
variations medium, medium italic, bold and 
bold italic would be listed in a sub-menu. 

As a further enhancement, the limit 
on the number of fonts in the font direc- 
tory has now been removed - you can 
have as many as you want (or as many as 
you can afford). 

Fonts are a major growth area for 
Archimedes DTP in the coming year. We 
have been working to increase the num- 
ber of fonts available at reasonable cost 
and can now offer three new ones. See the 
back page for further details.

Impression 
Junior 

If your needs are for basic 
DTP and word processing, 
Impression Junior offers a 
simple alternative 



Impression 2 offers a vast array of facili- 
ties for the widest possible range of 
publishing and word processing needs. 
However, not all users need such a high 
level of sophistication. 

If your needs are for little more than a 
word processor with some page layout 
and graphics facilities, it may be that 
Impression Junior is sufficient. 

Impression 2 sells at £169, whereas 
Impression Junior is just £89.95. So if price 
is your main concern, Junior fits the bill. 

What's the difference ? 

Impression Junior looks and feels very 
much like Impression, but with fewer 
menu options and overall simplification 
throughout. 

In choosing what features it should 
have, we cut out those which were com- 
plicated or only applicable to advanced 
page layout and professional publishing. 
If you just want an advanced word pro- 
cessor, you won't be disappointed with 
Impression Junior. Listed below are some 
of the major differences between Junior 
and Impression 2. 

• Simplified Master page system. 

• Basic printing options only: no pamph- 

let, collated, reverse, right/left only, 
no picture options. 

• Manual hyphenation only, no auto- 

matic hyphenation. 

• In-memory operation only - the maxi- 

mum document size is restricted to 
available memory. 

• Greatly simplified styles. 

• Limited attributes only - no double 

underline, strike-out, rule-offs, tab 
leadering. 

• Limited colour control - no CMYK and 

HSV colour control systems. 

• No abbreviation expansion. 

• Limited facilities for long documents - 

no automatic contents or index 
generation. 

• Simplified spelling check options. 

• Just one simple window per 

document. 

• Simplified preferences, alter frame, 

info, alter graphic dialogue boxes. 

We aim to have Impression Junior ready for 
release at the Acorn User Show. 




Hints & Tips * Hints & Tips 

This selection of hints and tips is confined to Impression and has been gathered from recent months of 

telephone calls and letters to the Computer Concepts' technical support engineers. It reflects a broad 

range of topics and, dare we say it, levels of user's knowledge! To these we have added some hints and 

tips which we think will prove useful. 

In future issues we would like to include answers and hints on other Computer Concepts' Archimedes 

products and welcome your suggestions by letter, addressed to "The Editor". 







uave Your Phone Bill 
... Read the Manual 

We know that the Impression manual 
doesn't make the most interesting bed- 
time reading, but it's worth taking the 
time to read it nonetheless. 

You'd be amazed at the number of 
letters and phone calls we get which are 
clearly answered in the manual! It's a 
waste of your time and your phone bill 
calling us with these questions. But it 
wastes technical support resources too, 
and that means less time for genuine 
problems. So please, before you call us for 
support, make sure you have checked the 
relevant sections of the manual. 

Sometimes a problem comes to light 
after the manual has been printed. Such 
problems are usually not directly related 
to our software, but if we keep being 
asked then we try to provide information 
anyway. Hints and Tips which are not in 
the manual can be found in a document 
called ! Hints on Impression disc 2. Please 
read this briefly, but then check it again 
when a problem arises. It's often the case 
that maybe weeks later you'll encounter 
one of the problems described, but you're 
likely to have forgotten the answer. 

Some of the more commonly asked 
questions are covered below. Some of 
these have appeared in the Hints file of 
recently purchased copies of Impression, 
but we still receive a lot of questions on 
these same topics. 



Unwanted line breaks 

Sometimes it is undesirable to break a line 
between certain pairs of words, or 
symbols. Usually Impression is liable to 
split words at any space character, but in 
circumstances where you wish to avoid it 
you can instead insert a hard space. This 
looks just like an ordinary space, but will 
never permit a line break. To enter one, 
position the cursor where it should be, 
hold down the Alt key and press the 
Space key. 



What is the new 
SuperSample module? 

When the !Fonts directory is double- 
clicked on for the first time it causes two 
modules to be automatically loaded. One 
is called FontManager and the other is 
SuperSample. The FontManager super- 
sedes and replaces the one present in the 
RISC OS ROMs. The other new module, 
SuperSample, can be seen at the bottom of 
the module list. This is just part of the 
enhancements to font handling which 
Acorn provided as an update - this is of 
no direct use to you - it has no interesting 
commands to play with, but please don't 
delete it !

'ocument renaming 

If you use the rename option on the filer 
window to rename an Impression docu- 
ment, the usual icon will be replaced by 
the standard application icon. 

This is due to the way Impression 
documents are stored, with an Impression 
Icon named the same as the document 
when saved. This icon will only appear if 
its name matches the document name, so 
if you rename the document, you will also 
have to rename the icon. You can do this 
by first holding down the shift key and 
double clicking on the document, which 
opens the document directory and shows 
the files within. Then double-click on the 
!Sprite file which will cause it to be loaded 
into !Paint where you can rename it to 
match the new document name. Alterna- 
tively, it's much easier to load the 
document into Impression and then save 
it with the new filename.

treating a custom 
setup for your own 
printer 

Inside each printer driver, accessed by 
holding down the shift key and double 
clicking on the printer driver application, 
there is a file called PrData. This contains 
details such as default paper sizes and can 
be examined or changed by loading it into 
a text editor such as !Edit. 

The file also contains two sequences 
called job_epilogue and job_prologue 
which enable commands to be sent auto- 
matically to the printer before and after 
printing. By editing the file you can create 
your own customised actions. One exam- 
ple of its use is to set the printer's form 
length for the size of paper in use. The 
codes for this and many other settings can 
usually be found in your printer's manual. 



Xrinting on A4 paper 

At the bottom of each page Impression 
sends a form feed command to the 
printer. This causes the printer to advance 
the paper feed to where it expects the start 
of the next sheet to be. Printers with sheet 
feeders are generally easy to handle, since 
their page size is not so critical. However, 
most dot-matrix printers are set as they 
leave the factory to expect continuous 
stationery with pages 11" long. In this 
state, the printer will advance to complete 
an 11" section when given a form feed 
command. If A4 paper is installed, having 
a length of 11.7", printing will be out of 
phase with the page start. 

Some printers have a small switch to 
set, indicating page length. For others it is 
necessary to send an instruction code. 

Referring back to the previous hint, 
form length on a Panasonic KXP1081 
printer can be set by modifying the 
PrData file in!PrinterDM, entering:- 
job_prologue = "<27>C<70>" 
This sets page length to 70 lines, which at 
the standard 6 lines per inch spacing will 
provide the correct size. Check in your 
printer manual for the codes relevant to 
the printer in use. 



Hints & Tips * Hints & Tips 



Linking frames 

There seems to be some confusion over 
the linked frame features of Impression, 
making them worthy of explanation. 

Linking text frames:- When some text 
has to continue across more than one 
frame, you don't have to treat them as 
separate stories. Instead, you can link the 
frames together in any desired order, and 
Impression will automatically flow a story 
from frame to frame. To create a series of 
linked frames, first create new frames in 
the required positions (although you can 
of course move and resize them later). 
Then click in the first frame to select it 
and Adjust-Click in the next frame in the 
required order. Continue to Adjust Click 
in each subsequent frame to add it to the 
linking order. Now, when you click in the 
first frame and type, or otherwise enter 
text, it will automatically overflow from 
one frame to the next. 

Note that you cannot add a frame 
already containing text to a different 
linked series. If in doubt, create a new 
frame or even a new set of frames, then 
you can be sure they're empty. One slight 
difficulty is that you cannot easily identify 
the linking order of frames. Just about the 
only way to see what you've linked 
together is to flow some text in and see! 
This doesn't usually pose a problem in 
operation. 

Graphics Frames:- Few users seem to 
be aware of - and even less make use of - 
Impression's feature which enables a form 
of linking of graphics frames. 

Two or more graphics frames can be 
linked by the same method as text frames: 
select click in one and then Adjust-Click 
in the second blank frame, and so on. 
What this achieves is to display a copy of 
the first frame's graphic in the second and 
subsequent frames. This is not only con- 
venient for duplicated graphics, but can 
also make considerable savings on disc 
space and memory, since only one copy of 
the graphic exists. The alternative is to 
copy a whole frame and its contents, but 
this is just a waste of time if all are to be 
based on the same graphic. 

Each linked copy can have its own 
independent aspect ratio, x/y offset, and 
scale. If a new graphic is put into the first 
frame, all of the linked frames will 
instantly show the same. This is a great 
time saver for repeating items, making it 
really quick and easy to change your 
mind at a later stage. As an example, each 
triangle graphic used as a page number 
holder in this newsletter comes from just 
two pictures - one for the left and one for 
the right, but there are fourteen of them 
shown in total. This saves on space and 
makes it easy to change in a later issue. 



iYdjust clicking 

It's often the case that the most useful 
little tricks are the least known, and mak- 
ing full use of the Adjust button certainly 
falls into this category. 

Adjust clicking on a dialogue box 
button or menu option will apply the 
operation, but won't remove the dialogue 
box or menu. For example, you can select 
a piece of text and bring up the style 
menu, then Adjust click on one style after 
another, seeing each applied without 
having to bring up the menu every time. 

If you want to set the widths of two 
frames to the same amount, you can select 
the first frame, bring up the Alter frame 
dialogue, and enter the width. But now 
instead of Select-clicking on the OK but- 
ton, Adjust-click on it. The change takes 
effect, but the dialogue remains on screen. 
Now click on the second frame, and the 
dialogue updates to show the correspond- 
ing settings. Now you can make changes 
to that frame, and then others if you wish. 

When copying frames from one page 
to another, and they need to be in the 
same position, bring up the Alter frame 
dialogue box, click in the original frame, 
make a note of the x/y measurements, 
then click into the pasted frame and 
change the measurements to match. If 
you now Adjust click on the OK button 
the changes will be made, but the 
dialogue remains. So you can click on the 
next frame on the original page, note the 
measurements, then apply them to the 
corresponding pasted frame, and so on. 
Scaling the view to approximately 25% 
allows more frames to be seen, and click- 
ing between the two doesn't involve 
scrolling. 



having disc space 

If you use the same document for a lot of 
letters, you can make use of the 'Save as 
text' option to save storage space. 

Set up a document as a template file 
with the basics of your letter structure 
such as the date, address, salutations etc. 
and load it each time a letter is required. 
Once the letter has been entered and 
printed, save just the contents with the 
Save text option, ensuring that the 'with 
styles' option is on. This keeps the text of 
the letter on disc, without duplicating the 
basic template every time. To start a new 
letter at this point, just delete the text. 

The archived text of a letter can be 
easily retrieved at a later date. To do this, 
open your default letter template, locate 
the text of the letter to be loaded and drag 
it into the main text frame of your letter. 



Xrinting side-by-side 

To print an A4 document side by side 
(A5) on an A4 page requires print 
dialogue settings:- fit lots on page, scaling 
66%, Sideways, as shown below:-

Print 



This is all that is necessary for a multiple 
page document. However, it takes a little 
more effort to print multiple copies of a 
single page document on a single sheet. 
You will need to create a new page which 
is a copy of the first. If it contains only text 
in the normal master page frame then 
mark the text and copy it, maybe using a 
'force to next page' command. If however, 
it is a more complicated page then the 
frames from the first page will need copy- 
ing and pasting one by one to the new 
page. See the earlier item about Adjust 
clicking for a time saving way to copy 
frames from page to page, whilst main- 
taining the same position. Once the page 
has been copied, set the print dialogue 
options as already described and print. 

Note: (a)entering 2 in the Copies box, 
selecting the Sideways option, and scaling 
to 66% will not give two copies of the 
same page side-by-side. Instead it will 
print two single sheets with a centered 
A5 page on each, (b) The Impression 2 
multiple frame selection feature will 
permit all of the frames to be copied in a 
single operation, (c) Impression 2 has an 
option for printing multiple copies of a 
page on the same sheet. 



Outlining Fonts 



A good selection of fonts is essential to the 
production of attractive documents, and 
the days of struggling with a few basic 
fonts on the Archimedes are well and 
truly at an end. 

When personal computers first 
started to be used for output of 'typeset 
quality' documents, traditional typesetters 
laughed at the idea, pointing to the 
extremely limited range of fonts and poor 
type quality as the reasons for their scorn. • 

Events soon overtook the die-hard 
traditional typesetters who quickly found 
themselves losing work to the few mem- 
bers of the industry with sufficient vision 
to embrace the new technology. 

At the forefront were Adobe Systems, 
creators of the revolutionary PostScript 
page description language. Adobe Post- 
Script provided the environment for 
traditional type designers to implement 
their fonts at low cost for use on small 
desktop publishing systems. Within just a 
few short years the industry has been 
turned on its head.

Adobe cornered the market, building a 
secret encription into their fonts so that no 
other pretender to the throne could 
understand and use their technology. But 
in a sudden turnabout last year, Adobe's 
position became threatened by the likes of 
BitStream, offering an even wider range 
of fonts of arguably superior quality. 

The supremacy of Adobe fonts came 
from their encripted 'hinting' mechanism. 
A straightforward rendition of a character 
outline at high resolution, such as that 
achieved on a professional typesetting 
machine at 1,270 dpi gives a perfectly 
smooth character outline, as you can see 
on this page. But at lower resolutions, 
such as 300 dpi achieved by most laser 
printers, it is difficult to avoid a rough 
jagged appearance at smaller character 
sizes. Methods which optimise the plac- 
ing of dots on such awkward points are 
called 'hinting'. The Adobe hinting

methods used in their 'Type 1 ' fonts are 
still the best around. 

Other font designers and providers 
now have wide ranges of fonts available 
in an Adobe 'Type 1' compatible format. 
For example, BitStream offer over one 
thousand fonts to choose from! However 
Acorn use their own proprietary hinting 
system which is unfortunately not com- 
patible with this industry standard 
'Type 1' format, hence the scarcity of fonts 
in the Acorn format. 

It is important now for the Archi- 
medes market to gain legitimate access to 
as many professional fonts as possible, 
and to this end we are now able to offer 
three new Archimedes outline fonts - 
equivalent to well-known traditional fonts 
- and intend to offer a much wider range 
in future. 

Each font pack is supplied as a set, 
ready to load and print. Available from 
Computer Concepts and our dealers at 
£29 +VAT per pack.

Production 

This issue of the Archimedean was created in Impression and completed in the final stages with Impression 2, using 

an Archimedes with 2MB RAM and a 20MB hard disc. All proofing and layout checks were output through 

LaserDirect. Final artwork was created by linking the Archimedes to a Linotronic 300 imagesetter running a 

PostScript RIP interface, outputting direct from Impression 2 with the PostScript Printer Driver, creating negative 

film. To maintain the highest quality, all photographs were converted to halftones and manually stripped into 

position using conventional methods, prior to making litho plates and printing.
