Summary

International Color Consortium (ICC) Version 4 differentiates clearly between perceptual rendering and colorimetric rendering so that the applications appropriate for each of these rendering intents are clarified. Improved workflows can be achieved by exploiting these definitions of clarified rendering intent. An understanding of image state concepts will assist in understanding and applying the ICC perceptual rendering intent. The distinction in the perceptual rendering intent is now explained: it provides a means to transition from one image state to another image state, preferentially adjusting color appearance for differences in any or all image state characteristics. In any ICC PCS-to-device transition, resulting in an actual output-referred image state, the selection of perceptual rendering intent versus one of the colorimetric rendering intents must take into account the image state of the image in ICC PCS and the similarities and differences between that ICC PCS image state and the targeted actual output-referred image state.
