I am having some issues etching a black-on-white acrylic material from Johnson Plastics - LZ901M, which is this material:
http://www.johnsonplastics.biz/detail/M37/1/1/LZ901M
It etches beautifully (removing the top layer of black and exposing the white underneath in the etchings), but there is a lot of black dust on on the sides/back of the material when cut out, and this easily gets into the white etchings and smudges/smears/stains on the white when touched.
I am curious if any of you have heard of this issue before, and how you got around it! I can etch any other color (red-on-white, green-on-white, blue-on-white, purple-on-white...) and the dust is not an issue. I'm not sure if it's the actual material I'm using (I have considered using their alternative "lasertuff" material, or an inverted color material where I will etch the black areas rather than the white) or the settings, or what... but it is a big problem since as soon as the user touches it they stain the etchings!
I've tried everything I can to fix the parts after the fact - putting them in an ultrasonic cleaner helps a little, but not that much...
Any tips would be really appreciated!
