Hello:
I am new to color management and I have definitely seen its benefits. I am
printing on fine art papers using an Iris 3047. I have calibrated and
profiled my monitor and I'm using third party profiles prepared specifically
for our paper/ink combinations, so far the results have been very
encouraging. I would like to make my own profiles so I'm looking into
various color management software packages and I have a few questions:
1) When the initial ICC profile is made is it always made using Perceptual
rendering? Is there a time when you would use say Relative Colorimetric
rendering? Do you have a choice? ( I am referring to the creation of the
profile, not the application of the profile).
2) Yesterday I printed the two versions of the same file using the same
profile except that I converted ( RGB to CMYK in PS6.0) one version to the
profile using perceptual rendering and the other version using Relative
Colorimetric Rendering. Except for a very small loss of detail in the
shadows the version using Relative Colorimetric rendering was more accurate
in its color, the Perceptual version was off overall in color but had
slightly better detail. Is this a common difference between these two
rendering intents? The re-mapping of colors using Perceptual rendering
seemed fairly dramatic (and inaccurate) in its overall effect.
3) I have been looking at ProfileMaker 3.1, and Kodak Colorflow for our
profiling software. I have been leaning toward Profilemaker 3.1 . One of my
concerns is to have good control over total ink and the generation of the
black. Can anyone make a recommendation?
Thank you for your help
