Chuck,
Were you given a sample of the original etched glass they received in the past? If it was acid or cream etched, it is likely that the etch had very little depth to it.
You may want to try calling Libby directly to see if they even offer an acid or cream etch.
Would you please e-mail a copy of the image (Corel 10) for me to do a test? I still think a photo resist is the best route to go to get the sharpest image. I'll punish myself by trying it on a compound angled wine glass that I stock, but always dread doing.

David,
I was given a sample. It is etched very lightly.
I WILL contact Libby. I'll also email you a copy of the image, but I really don't want you putting your time and energy into it, especially with the compound curve.
AAAARRRRRGGGHHHHH!!!!!!!!!!
That thud you hear, is my head bouncing off the wall(s).

I'm not sure what your using to mask with the laser, and I don't have any recommendations for a material. But to minimize the lines you probably want something with a low burn temperature to minimize laser power. (Trying to kiss cut the mask)
Have you peeled off the mask after lasering? It's possible the laser is causing the problem. -little fractures causing a poor line along (under)the mask edge. I'm not sure if you're better off raster engraving the mask or vector cutting the outline and weeding.
It'll be interesting to hear about David Takes's results. Did you ever pursue the "paint as mask" idea?
(Have you scratch tested the IPI plastic keytags you were working on? Will they hold up to a pocket of keys? I'd recommend testing samples in several peoples pockets.)

Can an etching cream be applied to glass with compound curves using pad printing techniques?
