Martin,
I am not 100% sure that my observations were actually made on "optically
brightened" press sheets. It's very possible that these observations were made
on "mildly" or "not much at all" optically-brightened paper. I have to dig my
data...
I wish I was still seating next to the press room, then I could simply get up
and go pick a few sheets off the press on any job ran on a "good"
optically-brightened paper. But I will get to good samples of OB paper and
gladly share my findings then.
Believe me, there is nothing I want more than get to the bottom of this M1
business. If only for my own mental sanity 😊
/ Roger

That’s what we’d expect.
Why our proofing systems are now generating — and happy to pass — 40% black
tints with results like b -3.6 (on a substrate where b = -2) I have no idea?
Never used to see this in the days before 51 & 52 turned the whole world blue.
