Summary

ICC input and output profiles contain transforms between device data encodings and the ICC PCS. This chapter provides recommendations to assist in the evaluation of the colorimetric and perceptual rendering intent transforms in ICC v4 profiles. The three types of test discussed in the chapter are roundtrip tests, device model tests and subjective tests. The chapter provides a procedure for applying these tests. It should be noted that in general preview tags should not be used for testing roundtripping errors. Roundtripping results may be affected by the device characteristics, the profile, and the CMM. Profiles should be evaluated using several CMMs, preferably those that will be used in practice. For improved interoperability with v2 source profiles, it may also be desirable to subjectively evaluate BToA0 transforms using images that are in color encodings with reference media different from the perceptual reference medium (PRM).
