Setting Parameters in the Job Parameters Window 189

To select a calibration table for a job:

¾In the Calibration list, select a calibration table. The default calibration table is Normal.

Tip: For optimal printing performance, use the Normal calibration setting with Ink Saving (GCR) set to Medium.

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.

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

¾To set ink saving, select one of the following options:

ˆNone: no GCR is performed on the file, and the printer applies maximum dry ink coverage.

ˆLow, Medium, or High: the selected amount of CMY dry inks replaces the black dry ink.

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

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.

For more information about creating gradation tables, see Gradation Tool on page 131.
