Hi Dave and Mac
I thank you for your input dave and i have done something similar to what u did but on the glass
What i have found is that with it being glass the laser fractures a much larger area then most mats and i have had to change the scan gap to 0.2 and this improved this a heap and much of it has come clear
I still dont have photo quality yet but getting there
For good ref for anybody check out skipw thread

one of the best threads for info i have found many thanks skip
It has a good ref for scan gap and other info
I have found that running my power at 30 to 40 % is good for a fine engrave and speed at 40 to 50 % to keep the detail (i have a 50w laser m500)
I get some great pictures from this
Im still trying to work out how they are getting the fineart on mirrors but most dont do it and do it on acrylic mirrors so it seem to be not that common and i found i can get it on glass easy but the mirrors distort the image some
When i get some pics ill posts some
