Sorry for the lengthy post. Here's the backstory...
I've been printing successfully for several years now on my Canon Pro V1 and IPF6450. All my equipment (two monitors and both printers) has been calibrated with a Colormunki Photo device. I also have the paper manufacturers ICC profiles available. Last year I almost exclusively used the ICC profiles to print on my two printers with good monitor to print color rendition. I started out printing mostly in Photoshop and then migrated to Lightroom due to its easier to use printing module. The papers I use the majority of the time are Canson Baryta and Platine, and also Red River Baryta and Palo Duro Softgloss Rag. I use Perceptual color control for out of profile colors.
This year, after updating my Lightroom CC and Photoshop software, I started seeing color issues, mostly in the magenta and red tones. My purples are coming out blue! If I plot with the paper companies ICC profiles or my own profiles I get the same negative results. I can see the color issues before actually printing in the Preview panel that comes up and when actually plotting, the print comes out with the same color variance as the preview window. I have been unable to figure out what the heck is going on.
Now, going one step further...I generally never print with the printer managing the color, but being at ropes end I decided to give it a try. Low and behold...using Canon's printer profile with the paper toggled to Photo quality and 'Canon Semi-gloss' paper, both the preview panel and then the print closely matched the colors on the monitor.
I need help understanding this. Is it related to the color space (Adobe RGB) or something else? Did Adobe change their default color space? Needless to say, I'm going to have to print with the Printer managing color until I can understand what's going on and fix it.
Thanks for any help.
