Marking engraving laminate UNDER the protective covering

[Rodne Gold]

On Rowmark and on my imported lams , I can engrave with the plastic film on but NOT go thru the plastic and still get a black mark , Only tried this on silver and gold. It's like the plastic covering is "transparent" to the laser , it strips off in one piece and the substrate under is marked. Doesnt work if you want to go deep tho , then the plastic melts , it does work for a "just black" mark. Wierd!!!
Never knew you could do that , But I went to visit Vincent De Klerk and he had done it that way for a door sign , We strip the plastic off anyway and will probably continue doing it that way , but it might be useful for some application?

I must try that !!!!

Using white-over-black Rowmark, I have a big cleanup job afterwards so leaving the film on until after it has been cut would be a big help.

We bought some Rowmark and tried engraving it, and that's how it worked. We didn't even think that you should take the plastic off. Anyway now to find a use for this. A sign sounds like a good idea.

Interesting discovery, Rod! Did you use standard settings or go "light"?

cheers, dee

I tried with very low settings , but just upped the power till it marked ok.

Just tried it.
It did mark and the protective film came off whole, but the film had trapped the vapourised cap layer which then condensed near the engraving - it looked as if it would be even more difficult to clean up.
Worth a try though.

It works a treat for vector marking. I've been doing it for a while now.

Can I leave the protective coating on if I have to cut the Rowmark after engraving?

Rodney,

If you have some of JDS Laserblack aluminum try it same way. It lasers darker black then removing protective film.
Discovered this by accident.
