My understanding of the purpose of a well-made print profile is that,
theoretically, it is supposed to allow an image to be printed with colors as
close to the original image as possible on that printer. But, I'm finding
that there are color shifts when using many profiles, shifting colors the
printer is perfectly capable of producing towards some other color -- reds
toward orange, yellows towards green, blues towards purple, etc. Not all
those shifts are in the same profile.
Just to pick one as an example: a pro lab I'm working with provides a
profile that shifts the reds slightly orange and the blues quite purple. The
printer is quite consistent this way and it is also visible in PS
softproofing. (Yes, I can adjust colors while softproofing, but...) Not to
pick on any particular profiling software, but this one happens to have the
name Praxisoft in it. Oh -- and they tell me that they calibrate several
times a day & this profile has always had these results.
Is there anything that accounts for such shifts? Limited profiling software?
Target? Spectrophotometer? All of the above?
In other words: is there a way to get more correct profiles, or are these
shifts just a well known [except to me :)] fact of life that you learn to
compensate for?
