Acrylic "ghost" image

Hello all! I’m wondering if others have experienced a “ghost” when engraving acrylic… I’m getting this:

If you are not using some sort of masking the vaporized debris from the acrylic can re deposit onto the surface. Im pretty sure that is what you are seeing there.


You may be able to clean it off using either a specific acrylic cleaner, or paste toothpaste - do NOT use alcohol.


Welcome to the forum. I usually reverse my image and engrave from the back to avoid this kind of thing.

Thanks. I suspected that and will try med-tack paper. this material comes with a plastic film mask that is incredibly hard to weed… Hence the attempt unmasked.


That was reversed and engraved from the back.

I’ll give that a try, thanks!

Well then masking may be the answer.

No problem, I do the same thing removing the plastic films from acrylic as I’m never sure if its safe for the laser and annoying to test and record for me. If you are having a hard time weeding out the small pieces after the engrave try using a really sticky tape like gorilla tape to peel away all the small bits if that makes sense.


agreed, and thanks. Gorilla tape is my friend!


I’ll try paper mask. Thanks!
