So it may be a basic question, but why does Trotec recommend wrapping a wet piece of tissue around a glass or bottle when engraving? Here is a beer glass which came out Ok with no wet tissue.
However there is some degradation to the letter B in Bert and the Wi of Wishes, would these have been better if damp tissue had been used? This was engraved at power 45% and speed 25% 500ppi on A Speedy 300 which has a tube measured at 89.3watts.

Any advice appreciated. I want to get this right and not have the degradation in the image.
Cheers, Steve
