Setup/preset 4pass on monomeric vinyl on Latex 800?

[Theflex]

Hello,
Any tips on setup to print with 4pass that do not produce lining/bands, in monomeric vinyl for busadvertising?

Yeah I don't think you will get it perfect anyway but you can try to lower your optimizer to 10% or even less and increase the edge optimizer to 2-4px and 2-4drops.
Also do the manual advance calibration just to have the value in if there's problems.
