digital printing on aluminium composite material (dibond, valubond, etc)

I run an OCE Arizona 350XT flatbed printer and have had one heck of a time printing on aluminium composite material. After gently peeling away the protective film that the material is covered with, I still get "chatter marks" or light spots in the print. I have tried every chemical I can think of to clean the surface as well. 99% alcohol, 91% alcohol, mask-off & windex, just to name a few. The streaks and spots are driving me nuts!!!! Help!!!

Adhesion is not the problem. And it happens with all colors, light and dark.

The chatter and streak marks are likely from when you were removing the protective liner. Try taking the liner off with an empty core and see how it prints afterwards. When I had a Gerber Ion this was the only way I could get dibond to print without the streaks.

I have issues sometimes too with light colors showing streaks, especially if i don't pull the covering off evenly. We've been printing on on covered Masonite and the only way we have figured out how to remedy the streaking is to have one person wipe with a soaked lacquer thinner rag and one person behind to dry. This is a little trickier on aluminum though, but it can work if it is a last resort. When you wipe with the alcohol, does it show the rag streaks? I guess you could try to have someone dry right behind you and see if that gets you any results. I wish the inks would cover like they used to. On my Jeti 3150, we could sand and lacquer thinner and alcohol just about anything and it would only show if it was an extremely light color like under 25% ink.
