Color separation modes
Illustrator supports two common PostScript workflows, or modes, for creating color separations. The main
difference between the two is where separations are created—at the
host computer
(the system using Illustrator and
the printer driver), or at the output device’s RIP (raster image processor).
In the traditional host-based, preseparated workflow, Illustrator creates PostScript data for each of the separations
required for the document, and sends that information to the output device.
In the newer RIP-based workflow, a new generation of PostScript RIPs perform color separations, trapping, and even
color management at the RIP, leaving the host computer free to perform other tasks. This approach takes less time
for Illustrator to generate the file, and minimizes the amount of data transmitted for any given print job. For example,
instead of sending PostScript information for four or more pages to print host-based color separations, Illustrator
sends the PostScript information for a single composite PostScript file for processing in the RIP.
Emulsion and image exposure
Emulsion
refers to the photosensitive layer on a piece of film or paper.
Up (Right Reading)
means that type in the
image is readable (that is, “right reading”) when the photosensitive layer is facing you.
Down (Right Reading)
means
that type is readable when the photosensitive layer is facing away from you. Normally, images printed on paper are
printed Up (Right Reading), whereas images printed on film are usually printed Down (Right Reading). Check with
your print shop to determine which emulsion direction it prefers.
To tell whether you are looking at the emulsion side or the nonemulsion side (also referred to as the
base
), examine
the final film under bright light. One side appears shinier than the other. The dull side is the emulsion side; the shiny
side is the base.
Image exposure
refers to whether artwork prints as a positive or negative image. Typically, print shops require
negative film in the United States and positive film in Europe and Japan. If you are unsure about which image type
to use, consult your print shop.
To print an object on all plates
If you want to print an object on all plates in the printing process, including spot-color plates, you can convert it to
a
registration color
. Crop area marks and trim marks are automatically assigned registration colors.

Select the object.

In the Swatches palette, click the Registration color swatch
, located in the first row of swatches.
To change the on-screen appearance of the registration color from the default black, use the Color palette. The color
you specify will be used for representing registration-colored objects on the screen. These objects will always print as
gray on composites and as an equal tint of all inks in separations.
