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

Normal.

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:

ˆ

None: no GCR is performed on the file, and the printer applies maximum dry 
ink coverage.

ˆ

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

The 

Gradation list contains gradation tables that were created by the Spire CX260’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 145.

¾ In the Gradation list, select one of the defined gradation tables. 

Use this option to make last-minute adjustments to the print job after proofing.

¾ To select a brightness level for a job, move the Brightness slider to the required 

brightness level (the range starts from 

Light, which applies 

-15%, to 

Dark, which applies +15%). 

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

No GCR

Low GCR

Medium GCR

High GCR

Tip:  Select 

High for minimum ink coverage and thus save on toner. High also 

prevents curling effects.

Note:  The default setting is 

None. No gradation table is applied to your job.
