Hello:
I wrote the list about a week ago asking about rendering intents and
Profiling software. Since that time I have purchased ProfileMaker Pro 3.1
and so far I'm very happy with the results I've been getting, thank you to
all who responded to my initial questions.
Now, of course, I have a lot more questions. My main confusion is over
profile editing and the structure of the profiles themselves.
Here's what's happening:
Prior to creating my own output profiles I had been using supplied third
party profiles for our ink/paper combinations (printing on watercolor papers
on an Iris 3047) and the results were very good. After making my own
profiles (same ink/paper, Spectrolino/SpectroScan w/ ProfileMaker Pro 3.1,
perceptual rendering) I thought that the prints made with the new profiles
(without additional editing) showed better color, better detail and better
contrast than the third party profiles. However, when I compaired the gamut
views of my new profiles against the third party profiles (using Profile
Editor) I was shocked to see that the gamut of the new profiles appeared to
be considerably smaller that that of the third party profiles. Then, not
really knowing what I was doing, I opened a copy of my profile into Profile
Editor and simply bumped the combined CMYK curve into a slight "S" shape and
saved it as a new profile. When I viewed the gamut of this new profile
against the gamut of the third party profiles it was now significantly
LARGER!
Here are my questions:
1) Am I placing too much importance on the gamut view? So far the prints
made from the smaller gamut profile seem to look better.
2) Are there other factors at work here?
3) Why would the gamut of my profiles seem to expand significantly by simply
changing the shape of the CMYK curves? It seems that I should actually be
reducing the number of colors available.
4) Finally, I noticed in Profile Editor that when you edit a profile you can
edit the output (rendering) tables and/or the proofing tables. Does this
mean that if a profile prints correctly but does not display on the monitor
correctly that you can edit the way it displays without changing the way it
prints?
Thanks for your help!
