All 3 images were printed at the same time, on the same piece of the Red River Premium Gloss.
The middle print is the control sample, the top one the ozone test, and the bottom one the UV test.
I think the UV test looks very slightly warmer, even in this scan. The shift on the ozone test
sample is undetectable w/o comparison to the control sample.
The images were scanned in one pass. The scanner is a Microtek E6. All automatic adjustment settings
were disabled.
