Just to review--Prints were pronting dark. (Darker than same pics printed on HP printer) Called Canon. Told me to bring it in to service. Canon sent me a new printer.

So here I am and the printer is still printing the same, so it has to ba a setting. I had been focusing on one particular print that had a beautifil blue sky and couldn't get the sky right. I printed out several other pictures and I've figured out it is NOT a problem with darkness. It is a problem with the blue. I am getting more magenta in the blue than I should be so the sky looks darker, grayer, or purpler. I printed a pic with green orange and yellow tulips and it was beautiful. Much sharper than the pic printed on the HP.

Then I tried printing other pictures with a lot of blue. Hydrangeas were purple and gray, There is some blue, but it is not as bright and clear as it should be. Next I printed a pic of a fish market where the fish were in bright blue plastic tubs. Definite purple overtone.

Any idea how to fix this? Thanks!

If the colors are out of the printer's color gamut it will be impossible to print them. You need to soft-proof the image in say Photoshop, and turn on the gamut warning. If the blue area is greyed out then you can't print that particular blue. The rendering intent (relative or perceptual) selected in the print window will remap that out of gamut blue color to another blue color that is in the printer's gamut even if it is incorrect.. Plus it is a known fact that monitor blues are brighter and have a difficult time with print to monitor matching. Remember the monitor is a transmitted light and the print a reflected light, colors will perceived differently.

Thanks, Bob, but I'm new to this. I have no idea how to figure out a printer's color gamut. I would think the pixma pro 100 could print any color. I printed the pics with blue on my HP (which no longer works) and the blue is bright and how I expected it to be. None of the pictures have been edited, but just came straight off the camera. In the pic with green, yellow and pink, the colors look identical to those in the HP print. It's just the blue that has a problem. Like I said, I'm new at this. I have an old copy of Photoshop, but haven't really learned how to use it yet. Thanks for any help you can give me.

Deep blues ( really are more toward what we call purple optically speaking ) are very difficult to reproduce by any printer. Your HP was very lucky to be able to do so.

Just about any good monitor will display a wider gamut that just about any consumer printer will be able to reproduce in print.

On your old copy of Photoshop, open up an image with the problematic blue. While you are viewing it. Click to the VIEW tab, then on the GAMUT WARNING Tab.

Anything the turned GRAY will be out of gamut or outside the capabilities of most printers to reproduce as you see it. The printer will do it's best to shift the values to at least bring them within the gamut the printer is capable of producing.

Those out of gamut areas if any will be changed to more, less or none if you then soft proof through the ICC profile for the printer and paper you are intending to print on.

Go to VIEW and PROOF SETUP and CUSTOM and then click on the PREVIEW BOX, and choose the ICC profile for your printer and paper, you can choose either PERCEPTIUAL or RELATIVE COLORIMETRIC and then toggling the preview box on and off you can get a idea how each rendering intent and the particular paper profile will affect the final look of your image's colors.

This is NOT a perfect 100% prediction of how the actual print will look but it is a pretty good approximation.
