Hi guys, I'm looking for insights other experimenters might have. I started with a clear acrylic sheet and had no luck etching it. So I painted one side with 'chalkboard black' and then tried again. It worked...sort of.
1) I dithered my image
2) set the speed down to 500 mm/minute
3) otherwise left the system in the analog mode that I used to etch plywood
Looking at the result, I need to generate a negative of my photo first. I see where plastic has been etched away which is good. I probably needed to increase the speed to 750-1000 for acrylic.
Here's my question. I'm ultimately looking to use this same process on the backside of a mirror tile that I picked up at home depot. Would I be better off not dithering? Has anyone tried a variation of this themselves?
