I have a 20w laser engraver and i want to engrave a colored image on stainless steal. some thing like the one in the image that i posted. how do you draw something like this in Lightburn.
Test, test test. Lots of material testing to find out what color you can make on different metal.
Honestly, that is A.I. generated. There is no way to get that kind of output from your diode, imho

so what you are saying is that there is no way you can do this on stainless steal with a 20w laser engraver

You can perform material test to find out what colors your diode can produce. As far as the art work, not a chance, Imho

Why don’t you write an email to the Longer manufacturers and ask them how to do it.. it’s in their add…?

I suggest you do a search on the forum.
Engraving stainless steel with a laser diode is a widely debated and comprehensive topic with a lot of information and technique involved.
After you have all the information you need and “just” adapt it to your specific machine, which boils down to what @JimNM mentioned.

I have a 60W JPT M7 MOPA and I’ve dealt with colors or should I say attempted colors.
One of the issues, is you have to take into account the metal removes heat very fast, unlike other materials. The type of metal matters, you can only get a range of colors from titanium and stainless. You can get the colors, but making use of them is another issue.
The problem occurs when you change, either, the image size of the physical size of the image. You don’t get the same colors when this change occurs. I have a stack of marked stainless, I don’t waste my time with color anymore.
Try it and see what happens… This is from the NIH and details Laser-induced plasmonic colours on metals
Worth a look, some great photos, like this one.
I agree with most of the others, it might have the power but getting to the metal is another thing.

agree with your comment , also no 2 pieces of metal are the same density which happens during processing, you will never get the same colours twice using same image and settings, ive done the trials, milled stainless is easier to work with than polished
