Keep the color quality high
About calibration
Calibration is very important in keeping the print quality high for color reproduction. The
environment of your print system influences the print quality. A constant temperature and
humidity are essential for consistent color output.
PRISMAsync automatically keeps the print quality as high as possible. However, additional
calibration is essential to keep the color reproduction level stable for all the media types you use.
PRISMAsync offers a structured workflow and feedback mechanism to integrate calibration into
your daily work.
There are two methods of calibration: the 
printer calibration and the media family calibration.
Printer calibration
Printer calibration has two procedures:
Shading correction
The shading correction includes precise adjustments of slightly uneven color densities in color
planes.
Automatic gradation adjustment
The automatic gradation adjustment includes precise adjustments of the gradation, density
and color quality of the primary colors.
The printer calibration settings on the control panel show which printer calibration procedures
are configured for your print system. The dashboard of the control panel will show the printer
calibration indicator   when printer calibration is required.
Configuration of printer calibration
IMPORTANT
It is strongly advised to configure the shading correction and automatic gradation adjustment for
the 
daily printer calibration.
A test print is used to scan and correct the irregularities automatically.
To find the configuration for shading correction and automatic gradation in the Settings Editor:
[Color] -> [Color calibration].
Media family calibration
PRISMAsync provides, as default, the 
coated and uncoated media families. A media family is a
set of media with the same output profile (one per halftone) and calibration values.
Before you start a media family calibration, always perform the printer calibration.
A media family calibration is necessary for the following situations:
• After the installation of the print system, for the default media families coated and uncoated.
• When a new media family is created.
• When your service representative replaces system parts.
IMPORTANT
Besides the listed situations it is advised to perform the media family calibration regularly.
Media for calibration
The printer and media family calibration need media.
