To ensure that the final printed output is the color you want, consult your printer or
service bureau and choose your custom color based on a printed color swatch. Manufac-
turers recommend that you get a new swatch book each year to compensate for fading
inks and other damage.
Important: Photoshop prints custom colors to CMYK (process color) plates in every
image mode except Duotone. To print true spot color plates, create spot color channels.
(See "Adding spot colors (Photoshop)" on page
To choose a custom color:
1 Open the Adobe Color Picker, and click Custom.
The Custom Colors dialog box displays the color closest to the color currently selected in
the Color Picker.
2 For Book, choose a color system. (See
on page 264.)
3 Locate the color you want by entering the ink number or by dragging the triangles
along the scroll bar.
4 Click the desired color patch in the list.
Choosing a custom color system (Photoshop)
The Adobe Color Picker supports various color systems:
PANTONE Used for printing solid-color and CMYK inks. The PANTONE MATCHING SYSTEM
includes 1,114 solid colors. To select a color, use a PANTONE Color guide, printed on
coated, uncoated, and matte stocks.
To simulate a PANTONE solid color in CMYK, use the PANTONE Solid to Process Guide,
which displays a visual comparison of 1,089 solid PANTONE colors beside the closest
process color match.
PANTONE process guides let you choose from over 3,000 CMYK combinations, printed
coated and uncoated stocks.
TRUMATCH Provides predictable CMYK color matching with more than 2000 achievable,
computer-generated colors. TRUMATCH colors cover the visible spectrum of the CMYK
gamut in even steps. The TRUMATCHCOLORFINDER displays up to 40 tints and shades of
each hue, each originally created in four-color process and each reproducible in four
colors on electronic imagesetters. In addition, four-color grays using different hues are
included.
FOCOLTONE Consists of 763 CMYK colors. FOCOLTONE colors help avoid prepress
trapping and registration problems by showing the overprints that make up the colors.
A swatch book with specifications for process and spot colors, overprint charts, and a chip
book for marking up layouts are available from FOCOLTONE.
TOYO Color Finder 1050 Consists of more than 1000 colors based on the most common
printing inks used in Japan. The TOYO Color Finder 1050 Book contains printed samples of
Toyo colors and is available from printers and graphic arts supply stores.

Newspaper Color Ink Book contains samples of the ANPA colors.
