some shrinkage in large fields

A project log for Powder coat pcb with toner & laser sinter

So we powder coat a blank PCB with laser toner. Selectively melt with laser engraver and maybe get some good results.

I tried another board with large fields, I see shrinkage afterwards along the direction of laser travel. Might need to color these in with sharpie in certain cases, or do the borders & use paint/tape etc. I don't see this as a big problem, as long as I'm not fixing little stuff I'm happy.
