Well, after trying several of the suggestions, I finally have acceptable (for me, and I'm picky) engraving. I owe you and Logojohn and Harvey and Carl a drink. If you're going to be in Vegas, I'll buy. It was a combination of several things that worked. I tried so many that I'm not sure what I did. I just saved the settings and I'm going with it. Thank you all very much for the help!
I hate the learning curve.

I don't know if I missed this in your posts or not, but is the image you are engraving a vector image or raster (or combination)?
If it's a raster or combination, maybe do a test engrave using a simple vector image with a solid rectangle and see if it has any bands.

The answer appears.
The dithering in the filled rectangles is conflicting with the DPI of the laser. Convert those to bitmap at an even multiple of the laser's DPI and it is solved.

Thanks Harvey, I will give that a try.
As you know I had a problem getting to the EE site. I thought I'd try another computer. Haven't had time to try the fix from Computer Associates on the other 2 and I'm a little gun-shy about using my work computers until I've done all of the diagnostics.
I appreciate your help with everything.
