Hello Diego.
Sorry to inform you that I obtained the same results that you describe.
I also have tried the option "-e AdobeRGB.icc" that Nikolay suggested, but I
obtain very simmilar bad results. 
I don't know what we are doing incorrectly.
I have tested a different printer profiles with different JPG with diferrent
color space tag, and I obtain the same result. Is a similar result when you
softproof with PhotoShop with the option "maintain RGB values" enabled.
The command used was:
.\collink -v -ila -G -qh -cpp -dmt
ACPU.icm AdobeRGB1998.icc

.\cctiff -e AdobeRGB1998.icc
ACPU_v.icm PDITestImage.jpg PDITestImage_v.jpg




.\collink -v -ila -G -qh -cpp -dmt
ACPU.icm AdobeRGB1998.icc


ACPU_v.icm PDITestImage.jpg PDITestImage_v_no_e_option.jpg




I attach the JPG obtained using the "-e Adobergb.icc" option and the JPG
obtained without this option. Also I attach the original ICM and the
obtained ICM after using the collink.
If you need a freeware test image I think that you can use any of this
webpage: http://www.northlight-images.co.uk/downloadable_1/DL_page.html
I use the PDI Test from photodisc.com that also I attach you with their
license file on PDF format.
Best Regards,

Asunto: [argyllcms] collInk for softproofing

Hello recently our belowed Graeme Gill posted these command to user Xavi
telling could be good for softproofing
# Create proofing transform from output to AdobeRGB collink -v -ila -G -qh
-cpp -dmt Argyllv140_396parxes48Gris3Blanc.icm AdobeRGB1998.icm

# Create proof image back in AdobeRGB space cctiff
Argyllv140_396parxes48Gris3Blanc_v.icm skin_sky_p.jpg skin_sky_pv.jpg
So I tried these command but probably unfotunately i miunderstand the real
power of these command
Now I tell you what I did.
I though to use all the two command with an image of mine and using .icm
file created for a backlit panel to arrive to a jpg file show me the
But Unfortunately the jpg I arrive is really jellowish and tint uncolored.
(unfortunately I can't show you becouse is publish protected copyrith)
So I ask you the ICM profile I arrive with collink could be used in
photoshoph to soft proof? 
In any way normally I use the Icm file I create with argyll with colprof to
make my softproof in photoshop, Is this procedure correct? Or not at all.
tahnking you for any help I send you my best regards.
