Digital BW, The Print

Great information. Thank you. I actually did a color calibration of the
iPF6300 about two  months ago, so I think I am good there. You say that non
Canon papers are not optimized fully in the Canon plug-in for the ABW
equivalent, perhaps that is part of my problem here. Maybe the custom
profiles made for me on the Epson papers are not going to give me good
results across the board. I have not mentioned this, but I am having some
trouble matching my color prints also. When soft-proofing I have to make
significantly more changes than I think I should to more closely get a
match. That being said, I have soft-proofed with the Canon RC photo paper
equivalent and do not see any improvement. Can I safely say that because the
Canon profile does the same thing that my Epson profile is good?

Lastly, from what I have read, it looks like QTR does not support Canon
printers. Am I to assume that the QTR-Create-ICC utility will work with the
Canon?

Jim, I do almost all of my printing through the QTR Print program Roy wrote.
I have not let PS manage the colour conversion since CS3. I use the Canon
print plug-in occasionally, but I do the colour conversion manually and set
the plug in to "No Color Correction" (Output Profile). The custom profiles
for your Epson papers should be fine, assuming they were made correctly.
Perhaps you are running into colour management issues.

Try this. . . .  Use Edit/Convert To Profile in Photoshop to apply the
profile for your printer to your image. Use the Adobe engine, Black Point
Compensation and the rendering intent you prefer (Perceptual or Relative
Colormetric normally) during the conversion. Then, take the image into the
Canon print plug-in, set the Output Profile to "No Color Correction", and
print as normal. Let us know how that turns out.

When I suggested you use QTR I was referring only to the profile creation
component. The main body of QTR (the "RIP") will not work with anything but
an Epson printer. The QTR-Create-ICC will work with anything. You print a 21
step wedge (included) using the Canon ABW equivalent. You measure that wedge
with your spectro and feed the values into QTR-Create-ICC. The profile it
creates will attempt to make your output linear, and If you were in the
ballpark to start with it should nail it. You then apply this profile to
each image as I've outlined above, just before you go into the Canon print
plug-in to do your ABW-style printing.

Best,

Terry.
