AuthorSubject: Soft Proofing Versus Printer Color Space Conversion   [Go to Bottom of Page]

This is probably a question for Bruce.

Soft proofing in Photoshop shows a ‘close’ representation on screen of what the print will look like. PS does this by using the AtoB table in the printer profile does it not?

If I’m correct so far (? :)), what I want to know, is why, when I convert to the profile in PS it doesn’t look the same as the soft proof. I presume that a conversion uses the BtoA table of the profile, so they wouldn’t be identical, but they are quite different.

Furthermore, when converting profiles, my understanding was that the color numbers change, but the screen color essentially remains the same. However, when I convert from say Adobe RGB to a printer profile, the screen reorientation changes. Essentially the changes are in grey scale and slight color shifts. Obviously the RGB numbers change quite significantly, as this is now the printer color space.

I am wondering what it is that each representation shows me.
