    If I understood correctly that Perceptual is best if color gamut is critical and Relative Colorimetric is best for tonal range then would RC be better for Monochrome Prints?

    Very good discussion.

    I don’t believe there are reliable rules for this. These Rendering Intents are designed to deal with out of gamut colours. They each do it differently and the image appearance depends not only the formula but the character of the photo itself. The correct Rendering Intent is the one which makes the photo look best in your mind’s eye.

    ICC profiles and rendering intents know nothing about images or color in context. They ‘see’ and treat an image, one pixel at a time. On top of that, there are no rules in how a profile manufacturer produces a  perceptual rendering. Just like there are no rules in how one renders an image on transparency film. Velvia is no more accurate or correct than AgfaChrome as an example.

    Image creators can soft proof and pick an RI and select one based on the colors in context and what they visually prefer.

    Yes, printing monochromatic images with little or no color would best be done with RelCol…thats what I do.
