AuthorSubject: Odd profile behaviour   [Go to Bottom of Page]
S. Stefan Jonsson
Posted on Thu Aug 28, 2003 8:31 AM

A local newspaper here in Iceland has made a press profile available to the public. While the profile produces excellent results in the final printed paper I am somewhat confused by its behaviour inside Photoshop.

When soft-proofing an RGB image using Perceptual Rendering the image becomes considereably brighter on screen and apparently more saturated/vivid than the RGB original. This seems to be contrary to the expected behaviour of gamut compression. It is however a fairly accurate representation of the final printed piece (checking Paper White really seems to destroy the soft-proof though).

A Relative Colorimetric rendering seems to give a more accurate on screen soft-proof as long as the Black Point Compensation is checked. It's much closer to the RGB original. The newspaper reccomends Perceptual Rendering though.

Is there any logical explanation why the Perceptual Rendering should produce such exaggerated colors?

I can e-mail the profile if someone wants to see for themselves.
