I've been experimenting with cermark on a yeti cup and I'm it's rubbing off. I'm using a 30watt VLS2.3 and before I sprayed on the cermark from the spray can I cleaned the surface with isopropyl alcohol.
First I followed I tried 100% power, 25 speed, 350 ppi. The images turned out well but when I rub on it, it begins to rub off
So I started to read through the forums and saw most people typically go slower then what I was using and use higher ppi.
This one is 100% power, 14 speed, 660ppi and I still get wipe off
Is this something that can happen if I'm applying to much cermark?
