Tried magazine paper with my laminator to day. Went better than expected, but still not half as good as Pulsar paper.
I selected a page out of an advertisement from the local newspaper, color print, kind of thin cheap paper. I used a 4x6 layout with 3 copies each, of two different boards.
First attempt, single pass through the laminator. Toner only stuck in patches, but the paper came of pretty cleanly from the areas that the toner stuck to the copper, almost no embedded fibers. None of the 6 PCBs were usuable, and not enough to touch up with a pen.
Second attempt, paper got jammed in the printer. Very first jam on the printer, but luckily all I had to do was pull the toner cartridge. The paper was basically folded in half and slide right out. Easiest printer I've had.
Third attempt, ran the board through the laminator 3 times. Out of 6 boards, I had 2 perfect boards, one needed a little touch up, and the other three needed more work then I felt like doing, but could have used them.
Only thing that might have improved the last batch, would have been to set the print density to max. I just left it at 3 (middle setting, which normally use).
