The first step in the process is to establish the colors you see on the monitor as being identical to those delivered to the printer. The image you see in the monitor must always appear as you wish it printed. Adobe Gamma is one simple way to accomplish this, but lacks the accuracy of a hardware "spyder" device and software intended to create ICC profiles that bias the color settings of your video card accordingly (for this you want Adobe Gamma disabled).

Assuming that the sRGB-converted image you are sending to the printer is correct, then problems are likely due to an improper printer/paper profile. You can try various tonal correction programs (the "Test Strip" PS plugin from Vivid Details is one), or you can shotgun the problem by creating a test print containing every printer/paper profile that you have, hoping one will be "on." Usually a better way is to use a program like ColorVision (Pantone) ProfilerPlus that uses a reference image that is printed, then scanned in and analyzed to create a tailored ICC profile for the specific printer and paper used. An even better and more expensive method requires a small, dedicated scanner such as included with ColorVision PrintFIX.

Doesn’t the 960 have a print driver that contains color tweaks? Maybe that would be good enough to get you going, anyway…

Use the automatic colour management feature of the printer driver and be sure you are using the correct printer profile. Then turn off colour management in PS and unload Adobe gamma from memory (Ctrl+Alt+Del under windows will give you the list. If it prints OK then… Wonder why you need Adobe’s colour management at all!

Bart’s earlier response is right on the money. I would add that it also possible you are double profiling your output, or otherwise mixing up your printer source space and any profile you may have installed with your new printer driver.

Ian Lyons’s web page has cleared up similar problems for others: http://www.computer-darkroom.com/ps7_print/ps7_print_mac.htm

You may also find the following test strip useful, though it is easy to make one yourself:

Oh that was brilliant Alvie!

Hmmmm. Whatever id double profiling? I used the Canon program to un-install the S800 stuff, then installed the i960. Other than that I hadn’t changed any settings.

Thanks for your response Bart,

I have just replaced a Canon S-800 with a Canon i960. The prints have a distinctly magenta cast.

The first step in the process is to establish the colors you see on the monitor as being identical to those delivered to the printer.

They were with the S800 last week so I have no reason to suppose that the monitor has changed.

image you see in the monitor must always appear as you wish it printed.

What I did was to make the image on screen look the same as a printed version, then corrected it in PS 7, then re-printed. After three attempts the results were just about acceptable.

Adobe Gamma is one simple way to accomplish this, but lacks the accuracy of a hardware "spyder" device and software intended to create ICC profiles that bias the color settings of your video card accordingly You can try various tonal correction programs (the "Test Strip" PS plugin from Vivid Details is one),

Went to their Website, it must be the most perfectly circular site in the known unverse. Clicking on any three links brings you back to the starting point. Never did find a link to buy, nor any indication of the price. I cannot justify the price of some of the hardware/software combos, I’m just doing this as a hobby.

Doesn’t the 960 have a print driver that contains color tweaks? Maybe that would be good enough to get you going, anyway…

Don’t know, I’ve poked around with the Maintenance and Setup but haven’t found any way to adjust the output. Have e-mailed Canon, only had the auto response so far, still hoping.

If procedure in Photoshop is to print to the Canon profile, instead of to Printer ICM, and the Canon profile is also configured to be used by the driver, that would result in what’s called "double profiling" and in some cases (Epsons for example) this results in too warm an image.

Of course, the problem could be something else altogether. I recommend looking over the Ian Lyons material for a more complete explanation, and to see if you are set up correctly.

Good luck.

That was even more brilliant.
You’re my hero.
While you’re at it, why don’t you learn to reply properly?
