SHADES for PageStream
Introduction
Welcome to SHADES. "What is SHADES?" you may ask. SHADES is simply
a collection of gradient-shaded, object-oriented, clip art. SHADES uses
a hundred steps for each clip, meaning, to get from 0% color (white) to
100% color (black, red, blue, etc.) there will be one hundred different
shades in the clip. Bitmapped images, i.e. DeluxePaint and Digi-Paint,
use only 16 steps for a shaded object. 24 bit bitmapped images, i.e.
DCTV, can have up to 256 steps for shading, but file sizes tend to be
very big (too big to load on a two megabyte machine running PageStream!).
SHADES uses PageStreams' screen object fill to create its shaded objects,
this also keeps file sizes down (most under 6k after being loaded). In
determining what types of shades to include, we decided to take an
artist's point of view, that most everything can be visualized as a
simple shape. Example: a building can be seen as a cube that is
stretched; or, more complex, a human figure can be seen as a collection
of tubes and spheres. So most of the clips in SHADES are simple shapes,
but a few shapes, designed specifically for desktop publishing, i.e.
gradient backgrounds and picture frames, have been included. You will
also find that most shapes have reverse versions to be used as shadows.
Another advantage of object-oriented clips is that they can be
stretched, rotated, separated, and recolored. SHADES was designed to be
a fast versatile professional tool to assist you with your publishing
needs. We indeed hope that it does just that!
SHADES requires: an Amiga (any model) with at least 1 megabyte of
memory (2 megs recommended); Soft-Logik's PageStream 2.1 or newer
version. Recommended: two disk drives; hard-drive; laser printer
300 dpi or better.
o As always make a back-up of your SHADES disk before starting!
Getting Started
1. Load PageStream as you would normally open it. Open a document or
start a new document.
2. Pull down the File menu and select Append. A file request window
should open.
3. Insert SHADES disk into drive 0 or if you have a second drive use
that if you wish.
4. Hit ESC and type in the name of the drive that the SHADES disk is in.
Example: if you just have the built in drive that is on your Amiga,
then you would type in "df0:" (See the PageStream manual if you have
any problems Appending a document).
5. You should see the SHADES directory; click once on that. You should
now see a list of clips. Click on the clip you would like to use.
The name will show up in the lower dialogue box. Click on the "OK"
button.
6. You will notice that you can't see the clip yet. That's because
PageStream puts the appended document at the end of the current
document. Advance to the last page of your current document and
you should see the clip you selected (most clips are at least one
quarter to one half of a standard page in size). The appended page
is now part of your current document. So if you started with a one
page document you now have a two page document. Also you will notice
that the clip appears to be made up of only 8 or 9 different shaded
objects. This is because PageStream can't show all 100 screen
percentages on the screen. So it groups ranges of percentages.
7. Most likely you won't use the clip in its present position or size.
So lets play with it a little. To move the clip to the page you
want to use it on, click on the clip. Then, from the Edit menu
select Copy. Now, go to the page that you want to place the clip
on and select Paste, also from the Edit menu. Paste clip by holding
the left mouse button down on the page where you want the upper left
corner of the clip to be positioned. Move the mouse down to where
you want the lower right corner to be and release mouse button. To
keep the clip's same proportion, hold down the shift key while
pasting clip onto page.
8. You will notice size handles on the clip. You can stretch, rotate,
slant, twist, and resize the clip just like any other object in
PageStream.
9. When you load a clip its color is set at black shaded to white. There
will be times that you will want to change the color of the clip,
even if you are printing in black & white. First lets look at what
a clip is. The clips in the SHADES collection are made up of a
hundred slightly different objects of the same shape. When you load a
clip it is grouped together to make it easier to work with. Click
on a clip and select About from the File menu. It will show "101
objects" if you only have one clip and nothing else on the page. Why
101? Because PageStream counts the 100 individual objects plus all
the objects grouped as another object. To change the color you must
first ungroup the clip using Ungroup from the Object menu. Select
Fill Style from the Object menu. Select a color and click on "OK".
Important: Do Not select anything else from the Fill Style window
while the clip is ungrouped!!! Select Group from the Object menu.
It's important to follow these steps exactly to avoid losing or
moving part of your clip. "Why not just change the color when the
clip is losing or moving part of your clip. "Why not just change
the color when the clip is grouped? PageStream doesn't allow you
to change the color of grouped objects.
Tips
1. Use the "Rev" (reverse) version to create shadows underneath clip
for solid 3D effect.
2. To give a clip a lighter appearance without removing objects from the
clip, change the color as described above. This will work even if
you are printing in B & W.
3. To lighten a clip without changing the color (for professional two
and three color process printing), you can remove a few of the darkest
objects of the clip. Ungroup the clip, then unselect the group.
Select the five (or as many as you wish) darkest objects and hit the
delete key. Regroup clip and resize. This will give the clip the
appearance of being lighter and save you the expense of another
process color.
4. When combining clips, select the clips you want to combine. Then
ungroup all of the selected clips. Now select Group from the Object
menu. You should now have one object. If you don't do this
PageStream will get the clips out of order when you move them on or
to another page.
5. PageStream will print out all of the SHADES clips on a regular printer,
but it is highly recommended that you print to a PostScript device
i.e. laser printer, slide-recorder or imagesetter with 300 to 4000
dpi output.
Addendum
Printing
The smoothness of the shaded object(s) depends on the type of device
being used. For the most professional results a 1200 (or 1270) dpi
(dots per inch) imagesetter is recommended. For most, a 300 dpi laser
printer output is adequate. There may even be cases in which a dot
matrix or thermal printer output will be fine.
To print using a dot matrix or thermal (or inkjet) printer, just follow
the directions laid out in the PageStream manual. For those of you using
a PostScript device you may choose to use the tips listed below to obtain
smoother gradient output.
1. 300 dpi users: Change the number of lines per inch (lpi): Select
Configure Printer from the Global menu. Type in the following in the
Special dialogue box "f[35],a[45]". Select OK. Now print the page
like you would normally do. The initial "f" stands for frequency and
the "a" stands for angle. We found that setting the frequency at a
range of 25 to 45 works well when the objects are full size or full
page. You may have to experiment a little on your system. Note that
the smaller the frequency the larger the dots will appear and be
printed. Also the larger the object is, the more you have to decrease
the frequency from the original of about 65 lpi. The 45 degree angle
is standard for screens, but any angle can be used.
2. 1270 (or 1200) dpi users: Follow the same instructions dpi users:
Follow the same instructions above to change the lpi. Since the
Accuracy of the device is higher, the amount of change needed is less.
A 1270 dpi imagesetter outputs at about 133 lpi. The range we
found to work best is between 100 and 130 lpi. For smaller objects,
we found the default setting to be fine.
As you increase the dpi (2400, 2540, 4000, etc.) the amount you have
to adjust the lpi decreases. As stated before, the quality depends
upon the device being used.
