5-5 PostScript applications
Generally, PostScript applications send color information to the iR C2100/
2100S as CMYK data. An exception to this is an RGB image placed in the
document, which is sent directly to the iR C2100/2100S (unless you specify
special color management settings in the application). In addition, some
PostScript applications that allow you to define colors in RGB or other color
models can also send data to the iR C2100/2100S in those color spaces.
Color controls in PostScript applications are typically designed for printing
on an offset press, and some adjustments are required for printing to the
iR C2100/2100S. Displayed versions of colors you choose in these
applications may not match iR C2100/2100S output exactly, and named
colors may not print accurately on the iR C2100/2100S, since these colors
typically require custom inks.
Choosing colors in PostScript applications
With PostScript applications, you can create colors using any of the color
models supported by the application. All PostScript applications support
CMYK; some also support RGB and other color models based on monitor
display values. PostScript applications also allow you to choose named colors
using one or more color libraries, such as PANTONE (see page 5-6).
You should use swatch color matching to ensure predictable color printing
results with the iR C2100/2100S or to match your iR C2100/2100S color
output to colors produced by other print devices.
Swatch color matching
iR C2100/2100S user software includes several color reference pages (see
page 5-2). By choosing colors from these reference pages, you can be sure of
obtaining the same color from your copier/printer. For best results, calibrate
the iR C2100/2100S before printing the reference pages.
NOTE: Swatch color matching does not match monitor colors to printed
colors. For this you must use a color management system and calibrate your
monitor.
