I've print out a CMYK ramp on both devices and am using a Spectrolino with
KeyWizard to bring in densitometric readings. I'll then compare what came
out on the offset that I'm wishing to simulate to what comes out on the
Epson through the offset profile. I'll then tweak the output values in the
curve to adjust the additional distortions the Epson engine is introducing.
This is the process I was wondering was scientifically sound.
I've already done this by eye well enough for production (B+ range) but want
the most accurate, measured way to adjust the curve.
I recognize I could edit the profile (which is what my curve is doing) in
Photoshop with Doctor Pro or another editor using curves (and then some!) as
well. But I'm already on my way with the in-RIP adjustment, so be it!
I'd like to dip my foot ever so nimbly into this puddle by also
suggesting users do a thorough head check and clean before emulating
these procedures.
Not to suggest I would ever do a whole lot of ramping and curving
only to discover my dampers were dirty!
