Bleed Limit
A bleed is a printing term that refers to extending large swatches
of color, as in a rectangular background, past the physical borders of
the document page. You do this so that the block of color will extend
all the way to the edge and a little bit beyond. That way, when
the page is printed and trimmed, the ink is sure to go all the way to
the edge, as intended.
Normally, a bleed extends as far off the page as determined by the objects
you created and where you created them. But sometimes you may not want
thisfor instance, when printing multiples of objects on a single
printer page, as in label printing. Perhaps you drew the bleed so large
that it overlaps into the next label. Bleed Limit lets you specify the
maximum amount of bleed for the entire drawing.
Imposition Layout
Up to this point, weve been discussing print options in terms of
a full-page layout, with one or more pages. The Signature and N-Up options
from DRAW 8 have been combined into one drop-down list in DRAW 9 called
Imposition Layout. The Imposition Layout drop-down list offers quick access
to more commonly used layouts and impositions. Additional imposition options
and the ability to save custom presets are available from the full Print
Preview window, and we will discuss these in more detail later in the
chapter.
You can get a good sense of how Imposition operates just by scrolling
the list and watching the Mini-Preview. We created a simple four-page
booklet, but in DRAW we were lazywe just created each page as a
standard page, without regard for how they would have to be placed to
be printed as a booklet. As you can see in Figure 26.5, DRAW forgave our
laziness, thanks to the Side-Fold Card imposition, which automatically
created the proper signature for these four pages.
FIGURE
26.5 We didnt create these four pages
as required for proper signature printing, but DRAW did it for us.
Printing Signatures
Signatures are commonly used for high-volume book and magazine
printing. Pages are ganged together on a single sheetmuch
like our side-fold cards, but the sheet is printed on both sides.
After printing, the signature is folded and trimmed, producing a
set of pages ready for binding in the book or magazine. Layout Styles
are typically used for production of camera-ready masters for output
to an imagesetter, but you can use it with any output device. Thus,
you might use a laser printer to proof signatures before sending
the project to film.
You begin, as always, by defining the document page size in Page
Setup. Choose the size of one regular page (not a full signature).
Next, create the document, making sure to use the right number of
pages, be it 4, 8, 16, etc.
Printing signatures works something like creating a side-fold card.
In the example shown here, the signature has four pages, so each
block of eight pages in the document will represent the front and
back of a single signature sheet.

| WARNING DRAW
gets very confused if you try to print multiple copies of a two-sided
signature. If you are proofing signatures on your desktop printer
and need more than one set, its better to do just one and then
simply repeat the process. Either that, or take a trip to your neighborhood
copy shop.

Separations
This page of the Print dialog is devoted to the needs and requirements
of creating film for conventional printing. Making film requires that
each color used in a drawing be represented separately from the others.
And while it may seem obvious to some, color separations themselves are
not printed in color. Each separation is black and white, usually negative
film, from which your printer burns a plate for the printing press. Thats
when the specified ink color for each plate is applied, resulting in the
composite color product.
If you are serious about color work, sooner or later you will need to
create color separationsusually image-set film destined for the
commercial printer. You can also print color separations from a desktop
laser printer, but the quality is not sufficient for commercially printed
process-color work. Six hundred dots per inch is fine for many applications,
but making negatives requires that a whole lot of toner be put down, and
we have yet to meet a laser printer that can do it solidly and uniformly.
Silk-screeners sometimes use desktop printers for process separations,
because they typically dont require high resolution and halftone
frequencies (more on this later). Simple spot-color separations are not
as demanding as process-color work and can often be handled by a good
laser printer (as long as you avoid extensive use of subtle blends and
fountain fills). But whenever you want commercially produced process-color
printing, you are destined for a trip to a service bureau, and youll
become quite familiar with the Separations page shown below.

The Value of PostScript
Nearly all imagesetters are PostScript devices, as are many of
the high-end color proofing devices. So if you are likely to be
using service bureaus frequently, its advisable to own a PostScript
laser printer (or at the very least read Chapter 28, Publishing
to PDF, to learn about using PDF files as a PostScript preflight
option).
At $10 or more per plate, mistakes at the service bureau can be
very costly. Proofing on a PostScript laser printer cannot eliminate
all possible errors, but it can help minimize them. For instance,
after we prepare a .prn file using a Linotronic print
driver, we often copy the prepared file to a desktop laser printer
to verify the condition of all our plates. The pages look clipped
and sometimes rather ugly, but at least we know all the pieces are
there.
Without a PostScript printer, we wouldnt know this. We could
print separations, but they would not be fully representative of
the .prn file bound for the service bureau.

To create separations, you simply check the Print Separations check box.
When you issue it, many elements of this page come to life and you will
be faced with numerous decisions.
The most important part of this dialog is the bottom portion, where the
colors that are used in the drawing are shown. If nothing else, this dialog
is an excellent troubleshooting tool: if you are creating a two-color
jobBlack and Pantone 342 and Magenta and Yellow appear when
you click Separations, you know that there is some object hiding somewhere
with wrong color assignments. The preview can help you isolate them, because
you can preview each color separately. In the graphic on the previous
page, you are seeing the parts of a full-color butterfly that will be
printed in Cyan.
Normally you will print all separations at once, but you have the option
of deselecting any colors you dont want printed. You can also tell
DRAW to print a plate for every color, even if it is empty for a given
page (using the Print Empty Plates option).
Here are some other notable options on the Separations page.
