From what I read, printing blue can be troublesome. I'm getting too much green (I think) in blue skies. I tried adjusting the color intensity in the printer profile by moving the blue-yellow slider to the left, but could not see any difference even up to -30. So I tried pumping up the blue saturation in Lightroom to +50 and that helped a lot. But it's a kludge - am I going to have to do that to everything I print?

So, should I try Profile Prism? Are there secrets in Qimage Ultimate that I have missed?

Just some quick thoughts before the Guru's jump in with better suggestions, and starting at the beginning...

Have you checked your colour problem area is within the gamut of your printer and/or monitor?

Fortunately, QU 115 now has a means of checking gamut.

However, if the problem area is OOG of either your printer or your monitor's display, you will have to rectify that issue to have even the faintest idea what to expect from your postprocessing adjustments.

Will stop now as I don't want to muddy the water for Fred and Terry who will doubtlessly give you better and more accurate troubleshooting information shortly.

More details: I do use profiles and the monitor is calibrated. AND, I just reprinted an old JGP photo with good blue skies and it printed the same as the original. I always use "perceptual" rendering. The troublesome photo was photographed in RAW, rendered to Photoshop as an sRGB TIFF, and then assembled with others in a panorama using MS ICE. Possibly something in that process is at work.
