Optic clear film not printing flat on UV printer

[uv]

I have been trying to print some optic clear film but keep getting ripples in it between the pinch rollers.
Anyone have any suggestions on how to make it sit flat?

Thanks

Anything on a clear liner is generally not going to run well in a printer. Print on a lam that has a paper liner, or better yet, a clear vinyl made for printing.
