HP 72SR manual Linearization

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 ink types or sets

◆Changing media types

◆Changing print mode (only if the most precise color match- ing is required)

Color calibration is a feature of the print server or RIP con- nected to the printer. Refer to the documentation that accompa- nies the print server for further information.

Tip	For best results, be sure that the color calibration
	patches are dry before taking readings.
Tip	If the camera height is not reset after changing the
	head height, a resulting color shift could necessitate
	performing a color calibration or creating a new
	color profile (with the ColorMark+ advanced color
	management system or third-party RIP). To avoid
	this, always reset the camera height after changing
	the head height.
