Red Ink Crinkling

[nikdoobs]

I am printing a double pass on clear vinyl. All other parts are printing fine except the red areas. The ink is doing a strange crinkling on the red parts. Anyone ever have this problem before? Any recomendations?

Pre-Heater=40˚c
Print-Heater=45˚c
Post-Heater=50˚c


TIA
Nick

The media is being over saturated with red ink. You need to reduce the amount of ink that is going down to produce the red.

Lowering the ink limit is probably the first thing you want to try, but if you don't get the quality you want after doing that, there's one other thing you can do: Set your RIP to return to return to origin after printing, then print two single passes in a row.

If you're running Versaworks, you have to add a cutting line somewhere in your file in order to make the return to origin setting available. Also note the sacrifice with this method is that a 4-5ft print may shift by a millimeter or so on the second print.

Thanks for the help.
