Hi guys.

I've got some laptops or keyboards (without backlight) and i need to add some charcters on their buttons.

Because of specific plastic they cannot be engraving by fiber laser - 100%.

I know there is way to make this job with co2 laser, but i don't know all details.

So here is my questions:
1) Laser system - i know that job can be done with epilog/trotec system, but i wish to it on scanator-based laser. Is it possible?
2) Also i don't know laser system power (10w or 20w)
3) Engraving settings (1 for foil , 2 for plactic)
4) masking material - what should i use
5) color ink - whick paint i should buy
6) descibe process - how long i shoud keep pain and foil before take it off.

Here is job that made my competitor: Click image for larger version.

I found this video - Using LaserBits Pro Color Fills - YouTube it helps, but can't detail answer on my questions.

Thank you. And sorry for my english.
