This chapter provides guidelines for defining colors in your documents to produce the 
results you want. The following topics are covered:

• Factors affecting how you work with color

• Choosing colors in applications that rely on GDI or QuickDraw to communicate 

data to the printer driver, such as presentation applications and word processing 
programs

• Choosing colors in applications that have the ability to write their own PostScript, 

such as some page-layout programs, illustration programs, and pixel-editing 
applications

See Chapter 1 for information on the differences in color management support 

between the PostScript driver and the PCL driver.

The two main factors that influence how you work with color in the creation of 
documents are the application you use and the final print device. Applications vary in 
the methods they provide for choosing colors and in the way they transmit color data 
to the print device. 

•

 such as presentation software, spreadsheets, and word processing 

programs use the RGB color model. They typically transmit only RGB data to the 
print device.

•

 use both the RGB and CMYK color models but typically 

transmit only CMYK data to the print device.

•

 use both the RGB and CMYK color models. They also 

transmit both RGB and CMYK data to the print device.

The type of printing you plan for the document—short-run color printing on the 
Fiery versus color printing for eventual printing on an offset press—determines the 
way you define colors as well as the print option settings you choose.
