Optimizing the Color Printing
Optimizing the Color Printing — Overview
Introduction
The colors can be manually tested by using the 'Color check' menu. In doing so the full
and half tone of each individual color is measured and optimized using a reference test
print job. This mode can last up to 20 minutes. When optimization is complete, normal
print operation can be restarted.
All the colors used in the printing system can be calibrated and as a result the active raster
kit adjusted by using the 'Calibrate color' menu. Two different types of color calibration
are supported:
■
Manual Calibration
Print samples are taken and manually tested using a handheld measuring instrument.
The measured data is then used to adjust the active raster kit.
Manual calibration can be carried out either on the console of the operator panel or
on an external measuring station.
■
Automatic Calibration
The measured values from the control strips, which are determined automatically
during the print operation, are used to calculate the new raster kit.
Note:
In the standard version, the 'Calibrate color' menu can be displayed from the "Key
Operator" user group. If necessary, a "Key Operator" for the "Operator" user group can
activate the menu.
Overview
The following tables display various applications for which optimization is recommended:
Note:
In many cases the cause of non-optimal print results may be due to non-optimal data
preparation.
