Color Management

This appendix provides information on controlling and managing color output in 
order to achieve predictable color results. It also discusses the basics of color 
management.

Controlling printed color

When working with color materials, whether they be presentations, illustrations, or 
complicated page designs, you make aesthetic decisions about the colors you use. Once 
you have decided on your goal, you then need to realize it in print. Your color printing 
system becomes an ally in this creative process to the extent that results are predictable

• If you designed a poster to print on the Fiery 3850C, you want the printed colors to 

match the design specification.

• If you are printing presentations on the Fiery 3850C, you want to preserve the vivid 

colors you see on your monitor.

• If you are working with color that will be printed on an offset press, you want the 

Fiery 3850C output to match other prepress proofs or PANTONE color swatch 
books.

The type of print job and the final print device, Fiery 3850C or offset press, determine 
the methodology you use to achieve the best results.

No matter what your goals are, two factors always impact color print output: print 
device consistency and the range of colors the device can print, known as its gamut. 
These concepts are covered briefly in this chapter. Creating successful color documents 
and presentations also requires an understanding of color management software as it is 
implemented by the Fiery 3850C and on your desktop computer. Most of this chapter 
is devoted to discussing the various elements of color management that contribute to 
predictable color results.
