Check Gradation
The Check Gradation feature allows you to print gradated color
patch prints for each line screen on the digital press. These
gradated color patch prints are used to verify that the dry ink/toner
densities for CMYK and Grey balance are correct. If you are
dissatisfied with the appearance of any color on the print, you can
manually adjust the dry ink/toner densities for Cyan, Magenta,
Yellow, and Black using the Manual Adjust feature. It is
recommended that you begin your calibration by calibrating the
300 PG screen first. This is the basic line screen that is used, and
all other line screens are calibrated against the 300 PG screen.
Use this feature daily and compare the output of gradated color
patches to the color patch prints from the previous day. Under
normal operating conditions, there should be no difference
between them. Automatic sensors and control mechanisms in the
digital press with scanner should maintain consistent calibration.
If there is an obvious visual difference between two days’ color
patches, run the calibration process on the color server, then run
this gradation process again.
