Ink Saving (GCR)

Gray component replacement (GCR) prevents the consequences of 
excessive toner buildup, such as flaking and cracking, and the "curling" 
effect that may occur when you print transparencies.

To set ink saving, select one of the following options:

ˆ

no GCR is performed on the file, and the printer applies 

maximum dry ink coverage.

, or 

the selected amount of CMY dry inks 

replaces the black dry ink.

Color Adjustments

The 

 list contains gradation tables that were created by the Spire 

CX250 color server’s 

tool. Each gradation table contains specific 

settings for brightness, contrast, and color balance.

When you select a predefined gradation table, your job is adjusted 
according to the specific table’s settings. 

Tip:  For optimal printing performance, use the Normal calibration setting 

with Ink Saving (GCR) set to Medium.

Note:  There is no change in the color quality of the printed image even though 
the gray component of each color is replaced by black

Tip:  Select High for minimum ink coverage and thus save on toner. High also 
prevents curling effects.
