I'm stumped! I have done a search of the forums and all those threads that start "I am a newbie to colo(u)r management....." but may have missed something or am just dense. Here goes-

I am a newbie to color management. Don't print many images but when I do, I pretty much get what I see on the monitor (LCD comes with set-up program to use with auto calibration + always confirmed with Adobe Gamma). Once used Elements 1, then PSP 8. Having finished a trial of CS, moved on to PSE 3 and full colour management. Printer is i865. Have read (and thought understood) the Canon ICC Profiles doc from maderito's thread http://homepage.mac.com/renard/ls/Canon_ICC_Profile_Guide.pdf and also Canon's Digital Photo Style site at http://bj.canon.co.jp/english/digitalphotostyle/ (from basic to more advanced - there is good stuff in "Retouching" - all has strong Photoshop flavour).

Printing PSE 3 edited Tiffs (converted from jpegs) from my wife's Optio 330 :rolleyes: (I am a G2/Pro 1 kind of person), the prints were generally ok (except most cloudy sky detail washed out) but the maroon reds in the school uniforms (here in Aussie) had a noticeable shift to magenta cast. More odd is that the teacher's brown suede shoulder bag has turned crimson! The colour balance for the rest looks ok but the greens (grass and trees are probably a bit oversaturated).

To cut a long story short, I have tried printing with/without Adobe/printer ICM enabled, tagged/untagged/sRGB/Adobe RGB, back to untagged original jpeg, manual/auto settings etc with similar results. At some point I worked out that the print preview was giving me identical results to the prints and I finally stopped wasting paper. Doh!

Then I tried Canon Easy-PhotoPrint :oops: (cringe) on the original PSE 3 edited Tiff (EPP does not normally recognise Tiffs but it does if you go through DPP 1.5 - although LZW compression still not recognised). Bingo! Almost perfect print match to monitor - no magenta shift, no over-saturated greens, sky still too light but not washed out as before. Same with vanilla jpeg.

What Have I missed??:cry: Any help will be much appreciated.

Wishing everyone all the best for New Year, hope that none of you have been directly affected by the tragic events in Asia and may we all work together to help those that have suffered.

Cheers,

Paul

OK, to close the loop I can now answer my own question. There were two separate issues. The worst was that most of the time I had printer ICM turned on at the same time as PSE 3 color management. (Despite having read this in several sources, it had not sunk in.) After disabling printer ICM, Photo Paper Plus Glossy gave result very, very close to monitor colours. Secondly, I had been using Canon Glossy Photo Paper for testing for economy reasons - bad move. There is no specific profile for this and I didn't expect the difference to be as great between the 2 Canon papers. After testing between SP2 and SP4, settled on my own profile of SP2 magenta -8 and yellow +8. Results were much better. As I am unlikely to use Glossy Photo Paper in a color managed environment, left it there without further refinement.
