Linearization
As the density of an image varies from highlights to shadows, or from lighter tints to darker tints, the
printer should accurately reproduce these areas in a predictable, or linear, fashion. The process of
linearization (or color calibration) involves printing and reading color test patches, and calibrating the
printer to ensure that the expected and printed densities will match. This in turn will ensure optimal color
matching.
You should perform a color calibration when:
● You notice a shift (change) in color output
●
Changing media types
●
Changing print mode (only if the most precise color matching is required)
●
You are about to begin a long run of many copies of the same print
● You are about to print a job that you may have to print again at some point in the future and match
the original color
Color calibration is a feature of the RIP connected to the printer. Refer to the documentation that
accompanies the RIP for further information.
For maximum accuracy, the photodiode must be cooled by its fan before reading color patches. The
control panel displays a countdown timer while the photodiode is being cooled by the fans.
