Calibration is very important to keeping the quality of the color reproduction high. 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 types of calibrations: the 

printer calibration and the media family calibration.

Printer calibration has two procedures:
•

Automatic gradation adjustment
The automatic gradation adjustment includes precise adjustments of the gradation, density
and color quality of the primary colors.

•

Shading correction
The shading correction includes precise adjustments of slightly uneven color densities in color
planes.

There are two modes available for the automatic gradation adjustment:
•

Standard
This recommended mode guarantees a high print quality for most print environments.

•

Professional
This extended mode is advised when you frequently use heavy and extra heavy uncoated
media or when you frequently use coated media.

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.

If required, consult a color expert to decide what you need to configure for printer calibration to
achieve the required color quality:
• The standard or professional mode for automatic gradation adjustment.
• How often to perform the shading correction.

IMPORTANT

It is strongly advised to perform the shading correction at least once after the installation of the

print system.

IMPORTANT

It is strongly advised to configure at least the automatic gradation adjustment for 

daily printer

calibration.

You can configure the required printer calibration procedures in the Settings Editor. Then, the
operator receives a daily reminder to perform the printer calibration.(See 

)

PRISMAsync provides default 

coated and uncoated media families. A media family is a set of

media with the same output profiles (one per halftone) and calibration curves.

Before you start a media family calibration, always perform the printer calibration.
