Perhaps someone with more expertise can kindly educate me a bit.
I'm working on a fall foliage image with strong reds and yellows. In PS Softproof, with my APS-made HP ID Satin profile loaded, a few areas of yellow showed as out of gamut. Not a big deal I thought, since softproof is really just an approximation. So, I printed through Qimage, as I always do. The yellow out-of-gamut areas printed BLUE. The same thing happened a couple of months ago when I was printing sunflowers, again, predominantly yellow. I've just gone back and printed through Qimage again, but this time using the HP Preview to see the job before it goes to the printer (giving me a way to cancel). Yep, the out-of-gamut areas show as the same BLUE. I understand that blue and yellow are opposites; did I go so far off one end of the scale that I circled around the back side of the moon and re-emerged at the other end?
Now, let's complicate matters just a bit. I initiated the same print job, but from within PS, using the same profile and intent, taking Qimage out of the loop. (Softproof still shows the same areas out of gamut.) But, the HP Print Preview window no longer shows these areas as out of gamut. I sent the job to the printer, and voila, those areas printed correctly in yellow -- as they should -- not blue.
I do not believe my workflow is problematic. Could it be that PS and Qimage handle the same data differently? And where did the blue come from? I am definitely confused on this one. Thanks for your help.
