Guessing bad chopper cylinders or control valve. Can be difficultto detect if you've never seen it.Can you print the colors on white/light with good coverage?
So, on the auto, you have the underbase and the top white printing well? Sounds like an ink problem on the colors. Are they halftones or solid areas? Do you need to clean the backs off much? Did you change your inks? How is your mesh tension? It could be getting picked up on each color. The top won't do that and the bottom base is flashed. Sounds like pick up and something with the ink.
Union ink on all top colors. Ultra soft or a mix to make an ultra soft.
It's possible that the flash is heating the ink to much, and curing the ink in the next screen?
Ok so I have been printing on my auto for over a year and I am getting really good at it. I understand how things work. I get the OEM thing.
