Title: Delta E baseline values in proofing
As a newcomer to the color field, I apologize if this is a commonly known value…
I am getting very good delta E (CMC1:1) values from one inkjet printer to the next as long as I am using the same media on both. However, when I use a semi-gloss proofing media with a large gamut to emulate a canvas or art paper with smaller gamuts, my delta E increases to around 2.2 for L values above 20.
This is measured by printing the RGB918 chart through color managed flow and measuring the charts. Text files are then evaluated and filtered (for low L values) in a spreadsheet. My measurement repeatibility is fairly negligible.
What is the lowest delta E values that I should expect from one media to another within the overlapping gamut of both? What is the best way to match or dumb down the gamut of one media to another?
Thanks.
Tim
