Hi, I have been very successful at creating proofing queues for
ProofMaster 2. I create them using the built-in calibrator and
MonacoPROFILER Gold.
However, when I try to create photo queue profiles I am very unhappy
with the results no matter how I approach it. When I let ProofMaster
carry out the conversions the shadows are plugged and the color is
flat. If I do the conversions in an Adobe application, the shadows are
great, but the color is flat.
The shadow problems are due to (lack of) black point compensation in
Proofmaster. I'm guessing you are using Relative colorimetric. The
problem is that you are converting from a colourspace with a black
point of (Lab) L-0 [RGB] to a printer space with a maximum achieval
black of, say, L15 (Could be as low as L6). Using relcol without BPC
will clip any shadow value under L15 to L15. Changing intent to
Perceptual will fix this. In a proofing queue you will usually convert
from CMYK where the black point already is around L15 (give or take).
In regrad to the colour if it is flat it is either you Profile,
linearisation and or media/ink that's the problem. Or it could be you
are sending images without profiles mebedded and have sat of assumed
profiles to a different profile space. for example there is a great
deal of difference of what you can achieve on a HP 5500 and an Epson
9600 (both pigmented) and Hahnemuhle paper. One is vastly superior
while the other can't take enough ink, thus inklimit must be reduced in
linearisation and/or profile app. resulting in good (non wet) blacks
but inferior colour.
Does anyone have any experience making photo queue profiles for
ProofMaster 2?
Plenty - it usually works a treat given the above limitations.
