Hi there,
We're having quite a bit of difficulty with on press ink-water balance performance. We get water marks across the cylinder and have checked and rechecked our roller settings numerous times. They are that close to being perfect it just doesn't make sense that we would be having this major a problem.
An ink representative (not our current one) suggested the other day on a visit that it could possibly be calcium contamination in the ink rollers. We use RO water before we mix our fountain solution, so we know the calcium is not coming from the water.
But we haven't done a calcium clean on the press - ever - I think. It's about 3 years old. So I'm guessing that there's a good chance we have a calcium problem.
However, when we look at the rollers I can't see any white/calcium build up. Could it possibly still be a calcium issue, even if I can't see any coating on the rollers?
Thanks for any input!
regards,
Dwane
