This is my second roll of 751 with the same problem ( Black). The silicone liner seems to be a little thin, when I pull the graphics off the liner with the transfer tape the paper liner wants to tear and stick to the back of the vinyl letters, I actually cut some white 751 first and then the black (the white pulled off the liner perfectly) I order a new roll of black and installed a new blade, set my cutter to "barely" scratching the liner and encountered the same problem. Has anyone else had a problem with 751 black? These rolls were dropped shipped directly from the factory.
