Wim,
I've profiled my Epson 3880 (pigment ink printer whereas the Canon printer
you have is dye based) for seven papers (combination of matte and gloss)
that I regularly print on using Argyll. After reading Graeme's tutorial, I
went down the simpler route and did not do the calibration step so I didn't
get involved with doing that and then the subsequent printing and linking of
the two files. My profiles turned out well as judged by both the gamut map
and how they worked on a test print image (see:
http://www.outbackprint.com/printinginsights/pi049/essay.html for the test
image). I used an 1848 patch set with an i1 pro (four letter size pages)
that included a 21 step gray wedge. Since I print on a Win7 system and
Epson only supports 8 bit printing, my charts were prepared as 200 dpi, 8
bit TIFFs (most commercial profile solutions have their targets in that
format so I didn't go to higher dpi).
Photoshop softproofing works fine with these profiles and I don't see any
difference between what is on my calibrated monitor and what comes out of my
printer.
I can't offer any solution to your profile preparation given I don't do the
calibration step. One thing you might do is compare your Argyll profile
with the available profile from the manufacturer of the paper you are trying
to profile. I've found that for the papers I print on the Argyll profiles
are better than those available from the manufacturers website.

Subject: [argyllcms] Create RGB printer .ICM to use in Photoshop CS5
Hi all,
I'm not new to argyll, but I'm quite new to the printer section of it.
I'm struggling a bit to create a normal icc profile for my canon i9900.
I'm using Photoshop CS5 to softproof and print my images. My workflow
for a "trial profile":
-> calibration
- Create CMY + grey step-wedge target for RGB printer
- Print target to 300 DPI 16 bitt TIFF
- Print on printer using the Adobe printing utility that disables all
color management
- read target
- create .cal file
-> Profiling
- Create full target for RGB printer
- Print target applying the earlier made calibration (K flag)
- Print on printer using the Adobe printing utility that disables all
color management
- read target
- Generate ICM file using colprof
-> Linking both
- Add .cal file to the ICM file
I'm not really used to this workflow as other profiling packages (PM5
etc) create an icc profile that has these correction curves included. Or
am I missing something?
Now, the above workflow results in some strange outcomes: the colours of
the softproof in photoshop are completely off (the same happens when I
convert to above generated icc file). The image prints ok (ok doesn't
mean as good as I want though), nothing like the softproof shows.
However, when I don't add the .cal file to the icm (last step), the
softproof is perfect but the actual printed image is horribly wrong.
I have the feeling I'm somehow applying the profile twice or so. Could
someone push me in the right direction? A basic workflow example of how
to generate a fully functional profile to use in Photoshop that shows
the softproof correclty and prints correctly would be very very welcome.
Many thanks,
Wim
