One of the more popular techniques to do on your laser is to laser engrave glass. However the quality for a lot of people has not been good enough. Some suppliers suggest wet paper but I do like this especially for large logos where the paper dries out. If you use the transfer mask and a good power setting you can get some very nice engraved images. Note: there is no sound on this video.

Setup – the final image is a black and white error diffused image that was inverted. See attached.
