Versant 2100 Color Accross Sheet...

[kdw75]

We have tried using the auto adjustment to balance color across the sheet, but still can't seem to get a consistent rose gold color from side to side. It seems like the yellow is more intense in the center, and weaker towards the edges. We also have an issue where the first couple of sheets in a run will have slightly less yellow, but then after about 10 sheets the yellow intensifies. We are on firmware .41, which the techs say is the latest they have, and we have had a new yellow developer housing put in.

We haven't had an issue with out inboard outboard color at all. I'm actually really happy with how stable the press is. What is the DeltaE variation across the sheet?

When profiling I usually get a Max DeltaE variation of around 2-4, but sometimes will get 6.

I re-profiled the other day, after we had a new IBT Belt, and 2nd BTR put in. I always use the approx 1600 random color blocks. I had it run two sets, and then averaged them. The first set out had a variation of 3.2, and the second was a 6.1.

That is variation from the characterization set, I'm wondering what the shift is from 1 side of the sheet to the other side.
