5-2 Working with Color in Applications
• For color proofing, use an application that writes its own PostScript and
define colors in RGB, CMYK, or choose colors from the application’s
PANTONE color library. Placed images can also be defined in RGB or
CMYK. Choose the appropriate settings for print options affecting color
output (see page 1-1).
NOTE: The iR C2100/2100S allows you to use RGB or CMYK data when
printing proofs for an offset press run. However, sending data to an
imagesetter most often requires CMYK data.
Color reference pages
iR C2100/2100S user software includes several types of color reference pages
that let you see the range of colors that can be printed on your copier/printer.
For predictable color, use the color reference pages when defining the colors
in your document.
• RGB Color Reference—a Microsoft Word file and a Microsoft PowerPoint
file that let you view the colors available in the standard palettes of office
applications and see how those colors print on the iR C2100/2100S (see
page 5-4).
• CMYK Color Reference—an 11-page downloadable PostScript file of
CMYK color patches (see page 5-6).
• PANTONE Coated Color Reference—a 19-page downloadable PostScript
file of color patches showing CMYK equivalents of PANTONE Coated
colors. This file prints differently depending on the setting of the Spot
Color Matching option (see page 5-6).
In addition, you can print RGB, CMY, and PANTONE color charts from
the iR C2100/2100S Control Panel.
