Setting Parameters in the Job Parameters Window 189
To select a calibration table for a job:
¾
In the Calibration list, select a calibration table. The default calibration
table is
Normal.
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.
¾ To set ink saving, select one of the following options:
None: no GCR is performed on the file, and the printer applies
maximum dry ink coverage.
Low, Medium, or High: the selected amount of CMY dry inks
replaces the black dry ink.
Color Adjustments
Gradation
The Gradation list contains gradation tables that were created by the Spire
CX250 color server’s
Gradation 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.
