First of all I want to excuse my very basic English language. Since some
days ago I have a problem that I don't know how to solve. I think that
someone could help me if I am able to express correctly. I hope that you
understand my first post on an English language mailing list,  and excuse
some incorrect words and incorrect expressions.


I have a printer Canon Pro 9000MKII, with third party inks (hobbicolor),
that I profile correctly (each one has different results but all are
acceptable) with the next combination of hardware and software:

-Datacolor 1005 Spectrocolorimeter + SpyderPrint

-Datacolor 1005 Spectrocolorimeter + MonacoProfiler



After reading some nice opinions, I have downloaded the latest verssion of
ArgyllCMS, the 1.4.0 verssion for Windows.


After some learning tests, I have understood how it works and reading some
examples of other users, I have started with a chart of 210 patches having
16 of the gray ramp.

The results were not acceptable when I use the perceptual intent due to a
very muted or washed blue color and a slight magenta cast. Blacks are deeper

If I print using the same profile, and the same paper, but using the
relative colorimetric intent, the blue color is perfect (not washed or
muted), but the blacks are more dark greys than blacks. Also I loose the
shadow detail.


Thinking that I will improve blacks and shadow details on relative
colorimetric, I have do charts with more patches: 396 patches with 48 greys
and 3 whites, 1188 patches with 128 greys and 3 whites and 1980 patches with
256 greys and 3 whites.


Using colorimetric relative intent, the blacks and the shadow details are a
little better than using the 210 patches chart, but incomparable to the 210
patches chart using perceptual intent. 


Using perceptual intent, the increase of the number of patches affects with
a slight intense blue color in comparison with using the 210 patches
version, but also inacceptable saturated blue color.


Using the other different combinations of hardware and software that I have,
and using perceptual or relative colorimetric intents, with the same ink and
paper, the blue color is intense, perfect,  the black are deeper and I see
details on shadows.


I think that I am doing something incorrect with ArgyllCMS or my process
need some tweak because as commented, using the Colormunki with their 25+25
patches I can use the perceptual and the relative colorimetric intents with
deeper blacks and correct shadow details and less out of gamma colors.


I want to mention that this issues are visibles on my print tests but also
visible softproofing on Photoshop. When I apply the softproof I see the
commented issues on the screen.


You can visually check here:

I have revised a lot of times all my process. From start to the end. I have
also added different options and/or changed others but without success.


I wish to explain here the process that I do, that is really very simple, to
try to detect what I am doing incorrectly.


I will use, as example, the case of the 396 patches chart, read by a

The other cases are the same but with more or less number of patches:


*targen -v2 -d2 -G -e3 -g48 -f396 Argyllv140_396parxes48Gris3Blanc


*printtarg -v -iCM -h -a0.83 -b -T360 -m3 -M3 -P -p220x338


I print, with Photoshop CS4, the generated TIFF using the latest version of
the XPS driver, with no color management on Photoshop and on the printer,
and using the same media settings that I use to create the profile with the
Colormunki soft. I do not assign nor convert the TIFF file to a color space.


I also have used ACPU to print the patches (without altering them) obteining
the same results.


*chartread -v -H -T0.4 Argyllv140_396parxes48Gris3Blanc


*colprof -v -qu -iD50 -o 1931_2 -S AdobeRGB1998.icc -cmt -dpp -D"Description
Profile" -O"NameProfile.icm" Argyllv140_396parxes48Gris3Blanc


I print or I softproof using the ICM file on Photoshop CS4 or CS6.


I think that the process is very simple but I am not able to find where is
my error.


I will post all the data that can affect the overall results:


O.S.: Windows 7 x64 Ultimate Edition

Printer: Canon Pro 9000MKII

Ink: Hobbicolors UW-8

Paper: HP Everyday Photo Paper (Cheaper paper to do a lot of tests)

Media Settings: XPS Driver, Paper Foto ProII, Quality 2, Difussion, 

Spectrophotometer: Colormunki

Software: ArgyllCMS v1.4.0 / Photoshop CS4/CS6

Intents used: Perceptual and Relative Colorimetric with black point
compensation enabled.


I will be so grateful for any advice you can give.


Thank you !
