MACtac did have one lot of B-free Window material where the ink on the backer transferred/embossed onto the face, but that issue has been resolved and any media still out there with this problem can be returned. It was simply too much ink on the liner, and it was an easy fix once reported.
MACtac is still the only manufacturer of B-free air egress window graphics designed for solvent, eco, latex, and UV. Available in clear, dusted, and frosted.
Mac - Tac ( I know....crap vinyl) makes one that actually works pretty well...It has a slight cross hatch pattern (like old 3M IJ-180). Be Free Air Release it is called I believe.
