Hello everyone. I need your professional opinions ... yet again.
Check out this page: http://www.gravograph.com/usa/Engraving%20Products/Doorplates.php Specifically the 3" X 11" brass door plate. What would you do to get a nice, visible black mark?
I've tried diamond drag. It doesn't appear to oxydize very well. I've tried sublimation (I have a black laser sublimation cartridge). It, too, is faint, plus it's hard to get good contact in the press because the item is not perfectly flat. I tried lasering a piece of trophy brass with Cermark (test piece before trying on the real thing). I got no discernable mark at all.
Any and all ideas would be greatly appreciated! :-)

I'm with Steve. Route and color-fill with black enamel.

Not bad for someone that couldn't even SPELL engraving 6 months ago, eh? :B

Now that you can spell it, let's see some examples! :-)

Between your Vanguard 3400 and the pantograph, you should have all you need.
Have you used that equipment for rotary engraving?

With a sharp cutter, the lacquer coating shouldn't be a problem, with respect to flaking.
To color-fill an engraved image, a depth of .010 is all that's necessary. With most material being much thicker than that, the chances of engraving all the way through are slim (so to speak).
There's a bit of a knack involved with deep engraving metal and color-filling. There's also a demand. There's also a limited number of engravers who can/will do it.
Why not join the group of those who can/will? :-)

If it is brass, not brass coated steel, it is solid brass.
To go .010 deep on some brasses to engrave without a burr you may have to go to .005, second pass to .009, third cleanup pass to .010. You will need BAL cutters. They have the angles and clearances needed for brass. A FLX bit will not do the job. High spindle speed is also required, with a low travel speed.
