I have decided to make a PCB with the help of traditional methods with clothes iron. The problem now is in the peeling process, there is a thin paper layer that is hard to remove , when I try to remove it with my hand the ink gets removed with it too.
When trying this way, I used rice paper because it dissolves in water better.
Maybe you have the etched board. If you can't remove the toner with solvent, use a fresh razor blade as a scraper. Just slide it under the resist and do a final clean up with solvent.
You can use acetone or MEK to remove the ink. Nail polish remover can be used, but it is more expensive and may leave some residue.
What you share on your post is quite useful.
