Printing 571

4) Registration stars

These are a further check that the separations are lined up.

5) Grayscale bar
This shows that the imagesetter or printer has rendered the full range of gray tones from
10% to 100%. It also provides the print shop with useful information during printing.
Useful for both monochrome and color work.

6) Progressive color bar

Similar to the grayscale bar. Provides the print company with useful information when
printing multicolor work.

7) Long registration targets (Not shown in the example)

These are an alternative form of registration targets. Some print companies may prefer to
work with this type of target. They replace the registration marks shown (option number
three) with this target type:

8) Overprinted color bar

Similar to the grayscale bar. If your document uses overprint, this provides the print
company with useful information during printing.

Print films

Films used to be used for press printing, but have been phased out by most print
companies in favor of PDF/X. But if you need to create films, these settings may be
relevant, and again only change them if asked to do so by your print company.

Emulsion down (reflect image): Creates a mirror image. This option, if enabled, will only
work when outputting to PostScript printers. The imagesetting material is coated with
photographic emulsion on only one side. With this option off, the emulsion is on the top of
the film when you can read it normally. This may be known as "right reading, emulsion
up". With this option on, the emulsion is on the back of the film as you read it. Called
"right reading, emulsion down" or "wrong reading, emulsion up".

Negative: Produces a negative image. This option, if enabled, will only work when
outputting to PostScript printers. Leave off if you are asked for "positive" or just "pos".
Turn on for "negative" or "neg".

Always overprint black: Overprints any objects that are over 95% Key (CMYK black).
Black is a relatively opaque ink and overprinting reduces registration problems. This
option is particularly useful if you have a lot of black text. If your document has large
areas of solid black, overprinting all black can cause problems with over-inking on the
press. Overprinting is described later in the chapter.
