Shari,
I do those type plaques on tile. I have a 25watt laser and I use 100p 20s and 500dpi. After the engraving I spay paint one coat let it dry and apply another coat. Both coats are not heavy. If the paint bleeds through a little bit just take a Qtip and a little spit and clean it up.
Hope this helps.

Shari,
Hope all is well I just got back from a week out of the office and it is real hard to get back into the work mode
Anyway regarding the spray paint I use Rust-Oleum black spray paint.
It seams to work the best for me The tile I did I ran at 100P 30s 500ppi I masked with transfer tape and then spray painted with two or three coats. Then to seal it I sprayed it with clear after all the mask was removed.
Your line width of 0.003 should be O.K. what might be happening is you might not be getting through the top surface of the glaze. These tiles are not very consistent in the glaze coating so it is better to go slower or do two passes in order to be sure you are through the top surface completely.
You could increase your line width to 0.007 to see if it helps it won't be noticeable on the graphic.
Good luck

Thanks for the info. I'll pick up some of your brand and try more than one coat. Maybe I'm not getting through the glaze deep enough. Will slow the laser down and see what happens too. The tiles are fairly inexpensive, so I'll try one thing at a time to see which works.
Will post a pic when I get a "good" one.
When you say transfer tape, is that the wide stuff that looks like plain masking tape? I have some that I bought several years ago from Bron tapes. That is what I used. I have to squeegee it down, but it sticks ok.

Shari,
Thats the stuff it cleans off pretty easily once you are done.
