For years I had printed grayscale images in RGB mode on my Z3100 with a Z3100-made profile for Epson Premium Luster paper. In adjusting the softproofed image I was always able to return it to neutrality by using the Color Balance tool, basically adding yellow in an adjustment layer (I use "simulate paper color" in the softproofing).
I just got an Epson 4900 and found it very difficult to come close to neutralizing the softproofed version of the image, as the color shift is not uniform across levels, and it seems to be off in more than one color, using the same Premium Luster paper. The actual print is very close to the softproofed image.
1) Does this seem like a problem with Epson's profile?
2) My only profiling equipment now is the Color Munki. Am I likely to get a more accurate profile for B&W printing than Epson's own?
3) If so, is there any Munki procedure that would be more accurate? (I have only the Munki software).
and, even though I'm afraid I know the answer,
4) Is there any way, using the softproofed image in CS5, to measure the color shift with eye dropper, color sampler, or other tool, and use the gray eyedropper in the levels or curves adjustment layer, to try to neutralize the appearance of the softproof?
