We use the laminator to mount the majority of our prints and cut vinyl. It works flawlessly. If the print is full-coverage, either 1) wait overnight for it to dry or 2) expose only a few inches of vinyl from the backing paper at a time. If you hold the backing paper against the mounted print as it comes out of the laminator, it actually removes itself at the perfect rate.
We use the laminator to apply transfer tape, also. Works great. Even if we apply the transfer tape by hand, I'll run it through the laminator to burnish or "squeegee" it down.
