Re: [datacolor_group] Spyder3 used to create Photo Rag profile - Gamut Problem?

2010-05-24 by C D Tobie

>>Now I notice that if I load a Colour Test image in photoshop and compare the out of gamut areas that are shown when soft proofing with the Hahnemuhle provided profile (from their website) vs the profile I created there are a lot more out of gamut areas in the darker colour areas. I am attaching a screenshot of what I see. The Hahnemuhle profile is applied to the left image and the Spyder3 built profile to the right image. Is this going to cause me some issues later? Will the printer have to make guesses about how to fit the non-gamut regions? I must admit the areas which are not out of gamut do look slightly better on the screen in the Spyder profile version...

The difference is more about how the two profiles measure the dark gamut of the combination than anything else; since the custom profile is actually measuring the combination at hand, it's results should be at least as good. But judge this from prints, not from soft proofs...
