Can anyone tell me what cause UV ink to pile on the impression cylinder of the procedding units ? is it ink water balance ? Thank you
Hello Raymond
One thing I can say from running uv om a royal zenith planeta 40inch perfector with grafix uv system in units 1-2-3-4- skip 5 and a double lamp in 6 for the uv coating.Yes it could be ink and water balance.Very fine line i tried to run as little water and ink as possible.Also could be ink, you may need a little more photo inishiator in the ink(dryer) consult your ink vendor . one more thing make sure you have the back pressure right on the printing units.
