Office applications
The Fiery 3850C 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 processors,
spreadsheets, and presentation applications. These applications use Windows Graphics
Device Interface 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 display. 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 3850C. (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, keep in mind that:
• 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 colors your printer can
produce.
• Office applications send only RGB data to the Fiery 3850C. You control the
rendering style of the color conversion with your selection of a CRD.
Each CRD uses a different color rendering style, and therefore has a different way of
mapping unprintable colors to the color gamut of your printer. Fiery 3850C color
rendering styles are described on page 1-4.
