Ensure high print quality
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 for print operators
Printer calibration has two procedures: shading correction and the automatic gradation
adjustment . In the Calibration window of the control panel, you can see which calibration
procedures you must perform. The control panel reminds you when to start a printer calibration
with an indicator. Color charts are printed during calibration. Load the media for the color charts
as configured in the Setting Editor (see below).

Configuration of the daily printer calibration
You are strongly advised to configure the shading correction and automatic gradation adjustment
for the
daily printer calibration. The shading correction assures consistent color planes on the
print. The automatic gradation adjustment includes precise adjustments of the gradation, density
and color quality. 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]
In the Settings Editor you can find the latest color calibration report.
To find the latest color calibration report in the Settings Editor: [Support] -> [Troubleshooting].
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 a service replaces system parts.
• When you want to increase the print quality for frequently used media families.
For the media family calibration you need the Eye-One spectrophotometer.
