Bill,

Reading about your purchase of PhotoGraV, I could have written that. I wouldn't use it on anodized either. (May I ask what you're doing with the anodized, and how you market/price it.)

I use PhotoGraV when the effective resolution of the substrate is low: wood, absolute black granite, glass...

It would be great if ULS added 2 parameters to their halftone function.
1) Lines per inch. It is now a function of engraving resolution. - Sometimes I want a higher engraved LPI, lower halftone LPI combination, than the driver's defaults.
2) Maximum spot size. - This can be simulated by shifting the grayscale away from black, so it's just a convenience.

As I have said before, I am very inpressed with what the XP driver from Universal can produce. By spending 1/2 hour doing it by hand and converting it to B/W I can get it faintly better, but not much.

I began doing it manually before that USL driver upgrade, tried the upgrade when I went to WinXP, and never thought about going back.
