Visual Linearity

Visual Linearity calibrates your printer so that it produces the correct
density. Use the

Kodak Digital Science Calibration Utility

Reference Card (reference card) included with the calibration utility to
select a cluster for each of the six density ranges. Visual Linearity
calibration prints look similar to the following examples.

NOTE:

For best results, do a Visual Gray Balance calibration before you
start the Visual Linearity calibration.
