Geez, that sucks. I've usually had good results on Gerber plotter
Leave the transfer tape on for a year......that will make it stick.
I have not purchased SignGold for over a year now so I don't know if they still supply their transfer tape with each roll of material or not but, they used to and it was the only thing that worked for me. High-tack Clearchoice transfer is pretty aggressive stuff and may work.
