Thanks for the quick answer, CD! But there seems to be something else
going on. Here's what I did:
1. Printed the TIFF targets (225 patch and grayscale) through Photoshop,
using the Export Module. I made sure the TIFFs had no imbedded
profile. In the module, Output Profile was set to "None (No Color
Correction)". All other color settings in module were set to default
(zero) positions. For good measure, I opened the Print With Preview box in
Photoshop and set Color Handling to "No Color Management" before opening
the module. (Don't know if that matters.)
2. Read the patches and built profile in Spyderprint 3 as
usual.
3. Printed thru the module, choosing my new profile as the Output
Profile. No other changes to any setting in module.
Result: Just like before! (Colors pale and lifeless, especially
purples and yellows.) The profile made thru the module may well be a tiny
bit different from the one made thru the driver, but it's not
obvious. The result is still obviously different from the print
made thru the driver, though, where colors are fine.
Any other ideas? Is there perhaps a hidden, low-level profile being
associated with the Canon 5100 somewhere else? Should I delete the
printer's "associated profiles" using Windows? I hear there's an issue
with the Canon module not liking Version 4 ICC profiles (though it doesn't sound
the same... that crashes the module). Are the Spyderprint 3 profiles
Version 4 or 2?
Thanks!
