Is the Proofgrade Sticker Laser Safe?



I’ve cut and cut and cut out of a piece of Proofgrade and what’s left is the corner with the :proofgrade: sticker left. Can I cut the sticker? Should I remove the sticker prior to cutting? Does cutting the sticker change the depth of the overall cut?


Might noticeably affect an engrave if it’s subtle. Shouldn’t affect a cut in any significant way on wood or plywood. The sticker is on the masking so it should peel off OK without residue.


Would be priceless though if the sticker isn’t laser safe on proofgrade materials.


All of mine eventually get chopped up. Believe me if they weren’t that would have been in the manual (and especially for us PRUs since it is THEIR laser we are cutting in…


I’ve had them ruin engraves but doesn’t affect cuts much. yes, safe.


Maybe you should have told the Glowforge to engrave the qrcode into the material while it was still stuck on, then you wouldn’t lose it… :smirk:


I haven’t played with proofgrade yet, but it seems to me you could flip it over, so the sticker is on the bottom.


great idea! I guess I’ve assumed that you must cut the top but it shouldn’t matter


haha. Of course with my torqued PRU lid, the camera often doesn’t work bottom right, so I am so used to just selecting the material off the menu, I don’t even wait (if it’s there it’s nice, but the magic of PG isn’t the QR code, but the settings).


The sticker also does not have to be right side up (readable by humans), just on the top of the sheet if you want the GF to find it. If you’re going to manually choose the PG material as @henryhbk (and I must admit myself as well) does then it doesn’t matter if the QR code is there or not - you just get that warning message on the bottom that it’s not detected.
