Malcolm,

I'm going to try the spray on photo resist and then a contact print. If that doesn't work, I'll be "back at the well" looking for more ideas.

You could use one of the etch resist pens on it though.

Jim,



Looks like a fun machine but a bit too complex compared to contact printing

and chemical etching.
