Title: Hue shift from monitor to prints
Post by: snowy on June 09, 2021, 03:29:00 pm
Hue shift from monitor to print

Epson P800, iMac 2019, Mojave 10.14, Eizo CE276, well-calibrated

I made 3 prints, for comparison, each with identical LR settings:
1) Canson Plantine Fibre Rag printed from LR,
2) Epson Legacy Platine printed from LR,
3) Epson Legacy Platine printed from Photoshop.

Printer Settings and Profiles used are correct for each paper.

The 3 prints are COMPLETELY, totally identical (good news), but all are shifted slightly from Hue 33 to about 13 on each print, losing the sepia color. In soft proofing, no difference between Perceptual and Relative. The Saturation is low.

I have done this for many years; and am amazed each time at how accurate the prints are. This time the consistent shift is bewildering.

Could this have anything to do with Mojave 10.14? Most of my printing has been on earlier OS’s.
Thanks much.

Sonny

And if you run the same prints outside of LR?

Yes, print #3 was printed from Photoshop. Looks exactly like #1 and #2.

You should always test output using good color reference images designed for that task. The color reference images RGB values are such they are set for output and are editing and display agnostic. Test the output this way and examine for the same color issues so we know it's not your image specific issues causing the problems:

Andrew, thanks for the references; it’s about time to do some more testing. I was so lucky in the past with the test images.
