Hi All. I just got a Canon MP830 (replacing an HP printer) and am having problems with a very slightly (but noticible) dark-yellow cast to the prints that I didn't have with my HP.

Though I have Photoshop CS2, my wife will mainly be using Photoshop Elements 4 for printing, so I need to concentrate on getting the latter right.

I've read through as many posts / stickies / FAQs I could find (including the Tech Corner ones). Here's what I've tried so far:




I've calibrated my monitor with Huey (hardware).

I've set PE4's color management to Optimize for Printing.

I've set the paper for Plus Glossy (Canon paper).

In the printer driver, I've tried setting Color/Intensity to Auto. This gives slightly washed-out/faded color pictures compared to the HP. I then tried setting Color/Intensity to manual and turning on ICC. That helped a bit, but still the prints come out a bit yellow compared to the monitor. I've even turned the yellow down in the printer driver a bit. My whites still are not as white as they should be. I've even played around with the Effects menu (Vivid options, etc) to no avail.

(BTW, I've also tried going to Photoshop and letting it do the color management, with the printer's ICC turned off. I used Canon's supplied ICC (the one that corresponds to my glossy plus paper) but that made things look abnormally pink; worse that just using the printer driver. I've even tried soft-proofing-- it looks great on my monitor, but comes out slightly yellow in the prints. I'm not sure it matters, but I did set the workspace to Adobe RGB.)

What am I doing wrong?? How do I get my prints to look like what I see in my monitor (using Photoshop Elements 4)?


thanks,

-- Frank

Check out my post on the MP830's ICC Profile color management http://stevesforums.com/forums/view_...mp;forum_id=40. There are a couple of good links which may help you solve your problem.

I am just starting to learn about color management and workflow. There are many causes for poor color management starting with your camera to the video card, monitor and printer you have. In addition, your choice of software for post-processing influences results. There are software and hardware solutionsfor calibrating everting from your camera to the printer. Also, temperature, humidty and ambient light differences from when you calibrated will affect color management/workflow. Changing inks and/or paper, usually meant as different brands than the OEM,will also require recalibration.

What monitor do you have. Whattemperature is it set at? IS your video card LUT capable? I don't know much about the huey, but from my reading, not all monitor calibration tools are equivalent on a specific monitor. Even withwell functioningmonitor calibration equipment, your monitor may not respond properly due to age (some say aCRT starts to deteriorate in two years) or difficulty withprocess of calibration itself (LCD's don't suffer from CRT's deterioration, but they may be difficult or imposible to calibrate due to lack of external controls during calibration or deformity of the screen from the puck). Some people complain that the "inexpensive" monitor calibrators just won't do a great job, close but not close enough. and that there is no way to edit/optimize the profile that results. I see that huey CAN edit a previously done profile - cool!

For your Canon printer used in conjunction with Canon paper, the Canon ICC profiles are probably the best bet in general. If the printed images appear off, the problem might beimproper ICC Profile selection (the default Canon ICC Profile is notnecessarily the best choice. See the link of my post to try selecting a better Canon ICC Profile.), conflicting color management (using PE4's color management which is not optimized for your Canon), conflicting software setup of printing parameters (do you need to turn off Adobe Gamma before installing/using huey?), improper printing (clogged printhead, misfired color or aftermarket inks - try a nozzle check or cleaning) or any of the other things I mentionedbefore. Reading through numerous posts, it seems that when the printed images do not match up with what's shown on the monitor, then the problem is monitor calibration (if inks and paper are OEM and the printer and monitor are setup and working properly). Sometimes it's just that the printer itself will not give the desired output no matter what tweaking you do - I hope not since I have the MP830 also!

There are so many things that can prevent a good workflow that it seems overwhelming at times. Do you need to calibrate your printer and camera?Hopefully notif you are using only Canon inks and papers, but your like/dislike of the output will dictate your decisions.

Other wesites that may offer guidance are:

http://www.northlight-images.co.uk/r...tone_huey.html (positive review. checkout the "Conclusions" section particularly the chart about Setting, Illuminant and Gamma and then the "hypothetical example" that follows.)

http://www.canphoto.net/articles/index.php?art/id:2 (not so positive review that may or may notbe relevant to your issue)

http://www.epinions.com/Pantone_Huey...splay_~reviews (the third review is negative but he has the same issue as you - too pink.)

http://dgrin.smugmug.com/gallery/1174347 (small review but the link at the end of the review that goes to Digital Grin Forumsmay help.)

http://www.northlight-images.co.uk/a...to_screen.html (this does a better detailed job dealing with your question than I could!)

http://www.normankoren.com/makingfineprints1A.html (back to the basics!)

http://www.microsoft.com/downloads/d...displaylang=en (a workaround? some like, some don't)

http://www.kenrockwell.com/tech.htm especially http://www.kenrockwell.com/tech/ps.htm (Ken Rockwell is THE man)

http://www.drycreekphoto.com/ (too bad they don't do custom ICC Printer Profiles anymore)

Last, if your monitor is calibrated correctly and you are happy with the printer but not the printouts, and you are end the end of your wits, do a google on "custom ICC Printer Profiles".

Let us know what you come up with.

Thanks for the detailed info.

I still haven't figured out why I'm having problems. The HP printer I had just replaced worked fine.

I did note that printing directly from a memory card (bypassing any software) gave good results. I thought that letting the printer do the color management (a choice in Photoshop) would do same thing, but there seems to be something else going on. I tried turning off/on ICM in the printer driver but that didn't seem to do it either.

Does PE2 load any drivers at boot, such as Adobe Gamma? If so, you might want to disable them (using msconfig maybe?), recalibrate and test print again.
