Specifying which colors to create separations for
In the Separation Setup dialog box, each separation is labeled with the color name that
Illustrator assigned it. If an icon of a printer appears next to the color name, Illustrator
creates a separation for the color.
Illustrator assigned it. If an icon of a printer appears next to the color name, Illustrator
creates a separation for the color.
To specify whether to create a separation for a color:
1 Do one of the following:
•
By default, Illustrator creates a separation for each CMYK color in the art. To create a
separation, make sure the printer icon is displayed next to the color name in the
Separation Setup dialog box.

•
To choose not to create a separation, click the printer icon next to the color’s name.
The printer icon disappears, and no separation is created.
Separating spot colors as process colors
You can separate spot colors or named colors as equivalent CMYK process colors in the
Separation Setup dialog box. When spot colors or named CMYK colors are converted to
their process color equivalents, they are printed as separations rather than on a single
plate.

A four-color process icon appears next to all the spot colors in the artwork.

Specifying the halftone screen ruling
The Halftone menu displays one or more sets of line screens (lines per inch, or lpi) and
resolutions (dots per inch, or dpi) available on the printer or imagesetter that prints the
color separations.
resolutions (dots per inch, or dpi) available on the printer or imagesetter that prints the
color separations.
A high line-screen ruling (for example, 150 lpi) spaces the dots used to create an image
closely together to create a finely rendered image on the press; a low screen ruling (60 lpi
to 85 lpi) spaces the dots farther apart to create a coarser image. The size of the dots is also
determined by the line screen. A high line-screen ruling uses small dots; a low screen
ruling uses large dots. The most important factor in choosing a line-screen ruling is the
type of printing press your job uses. Ask your print shop how fine a line screen its press can
hold, and make your choices accordingly.
