Color Reference Guide for C9800 - 23
The ColorWise color management system provides complete color management for
jobs printed from office applications and other applications that do not generate
PostScript. This chapter provides instructions for printing color documents from
Graphics Device Interface (GDI) and QuickDraw applications, such as presentation,
spreadsheet, and word processing applications. Use these instructions with the
Microsoft Office applications.
Using office applications
The Fiery must receive PostScript instructions to print an image or a document. Many
applications do not create these PostScript instructions, relying on the printer driver to
create them. Included in this category are most word processing, spreadsheet, and
presentation graphics applications. These applications use Windows GDI to display
and print when running Windows, and Apple QuickDraw to display and print when
running Mac OS. We refer to these GDI and QuickDraw applications as “ office
applications .”
All office applications handle color similarly, using the same RGB color model used for
the color monitor. Most office applications allow you to choose colors from a palette of
preselected colors; some allow you to add new colors to the palette using a color picker.
Although some applications allow you to specify color using the CMY, HSL, and HSV
color models, these applications always send RGB color data to the Fiery.
(An exception to this is a CMYK EPS file placed in the document, which is sent as
CMYK data.)
When working with color in office applications, consider the following:
• The range of colors that can be displayed in RGB on your monitor is much larger
than the range of colors that can be printed on your printer. When you print the
document, out-of-gamut RGB colors are mapped to the colors your printer
can produce.
• Office applications send only RGB data to the Fiery. You control the rendering style
of the color conversion with your selection of a CRD .
Each CRD uses a different color rendering style and has a different way of mapping
unprintable colors to the color gamut of your printer. For more information on
color rendering styles, see the
Color Guide Chapter 1 .
