    I'm trying to perf cut some backlit PET film media and the material seems to be slipping even when just feeding it through the cutter. I'm using a Graphtec FC8600-130 cutter and media is LexJet Simple Premium Gloss Backlit Film.

    This cutter seems to work just fine on other materials like static cling and floor graphic media which I cut both recently without issue. The tracking was perfect for both of those.

    I tried to pre-feed the backlit through first to help prevent slipping but it didn't work. I reached out to Graphtec and LexJet but I haven't gotten satisfactory answers from either. Graphtec is initially suggesting the media might be to blame while LexJet is saying the cutter isn't really designed to cut media without a paper backing. LexJet is suggesting I cut by hand or use an XY cutter.

    Anyone cutting backlit media on a Graphtec?

    Why don' t you try to stick a transfer paper at the back of PET? As LexJet said...

    Funny enough, the paper they suggested was a kraft paper with no plans on how to adhere it, however I didn't even think about a high tack transfer paper. Worth a shot, thanks!

    Well, I tried lining the back with RTape Conform 4075 High Tack transfer tape to improve grip but sadly it wasn’t enough. The material still drifted. I really don't know what else to do other than try a different backlit. But LexJet is saying another backlit like HP Backlit Polyester film would exhibit the same issues since the cutter isn't designed to cut backlit film like that.

    Am I using the wrong equipment? Is anyone else cutting backlit media on a vinyl cutter or am I the only one trying to do this? How do people normally cut backlit film?

    I'd say yes you are.
    We'd use a ruler&knife, javelin or flatbed cutter.
