Painting
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. Manufacturers 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, or process color, plates in every image mode
except Duotone. To print true spot color plates,
create spot color channels. (See “Using spot
channels” on page 245.)
To choose a custom color:
1
Open the Adobe Photoshop Color Picker, and
click Custom.
The Custom Colors dialog box displays the color
closest to the color currently selected in the Adobe
Photoshop Color Picker.
2
For Book, choose a color system described in
the next section.
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.
5
Click OK.
Choosing a custom color system
The Photoshop Color Picker supports various
color systems:
PANTONE ®
Used for printing inks. Each
PANTONE color has a specified CMYK equiv-
alent. To select a PANTONE color, first determine
the ink color you want, using either the PANTONE
Color Formula Guide 747XR or an ink chart
obtained from your printer. PANTONE books are
available from printers and graphic arts supply
stores.
You can select from PANTONE Coated,
PANTONE Uncoated, PANTONE Process,
and PANTONE ProSim custom colors. (Contact
PANTONE, Inc. in Carlstadt, New Jersey, U.S.A.)
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 image-
setters. In addition, four-color grays using
different hues are included. (Contact
