Ye gods man, how much are they charging you to use the laser?
That's strange--I would have thought that the best tool for the job
would be AJM (micro-bead blasting) --good for temperature-sensitive
stuff such as acrylic and leaves a finely-textured surface.
You might be able to do it with an ordinary sandblasting rig.
That might produce very nice results - CNC some masks from thin
aluminum or even steel, then use either pre-cut glass or acrylic digit
blanks in a jig, and give them a quick blast to etch the dots.
If I had access to a bead blaster, I'd try it.
