For engraving remove film. If you do both, remove film and engrave then before cutting apply paper transfer tape. This requires sending job separate.

Well I did already try and remove the film and then engrave. However it seems like the laser don't get through the black (I use black on white) at some places. It's like the acrylic is bent somehow.

I will have to test out your advice tomorrow, when I'm off to the fablab again.
