I don't know.

Are you ready for ther tour?

if its not paint, its usually the substrate material or the reaction you get when cutting the substrate (I think some laser cutters may etch aluminum black, etc) someone explained all this to me a looooong time ago.

That's an old picture CJ.
Can't release a recent picture.
Years and years of drug abuse you know

I've actually been in the Front Panel Express shop here in Seattle. They are located only about 10 minutes from me.

They have a unit in an industrial park. I saw 2 flatbed cnc routers working, there may have been more. There was a guy sitting at a bench with a respirator on, and he was rubbing out a panel with a rag. I asked if the paint fill was done by hand, and they said yes. I didn't see the whole process, so I don't know how the initial application is done. I did see a bunch of little syringes with different colors of paint in them.

I asked this question a while back and got no reply but since then I have seen a few web sites where the DIY version is this...

Basically the simplest way is to put the paint into the infill on the engraving and go over it with a credit card (left and right in a sweeping motion) and keep doing it..
But they seemd to be doing it with a sanding block
Still don;t know how they got the excess paint of the front panel "not to be engraved stuff"

just an idea, maybe they put some kind of coat on the frontpanel prior to engraving, then engrave, then paint, then wash it off ??

The local engravers uses an 'infill stick' that looks like a crayon. You buff the surface with a rag afterwards...

The local surplus stor had infill sticks a while ago... haven't seen any lately though.
