If you search the Ganoksin archives you will find a few discussions.
The problem is we keep spelling it differently: Image On, Imagon,
Imag-on. So try them all.
Here is an edited version of a previous description I had made:
I use a Samsung ML-2510 B&W laser printer ($100) to print the image
on overhead transparency material which becomes the “film” to expose
to the Imag-on “resist”. I use the ultra-violet light produced by a
household CFL fluorescent bulb (250-watt equivalent) to expose the
resist sandwiched with the film.
P&P is adhered by heat; always some degree of problem arises. To
adhere the Imag-on you use a squeegee and water. After exposure you
put the piece in a developer of washing soda and water.
The plastic resist that adheres to the metal is stronger than P&P
(lasts longer in the etching solution) and retains finer detail.
Results are the same every time.
Imag-on was developed for the print-making field, so most places
that carry it give instructions for exposing large sheets (for making
larger prints) and they need more complicated vacuum frames and
expensive light sources.
It can seem very overwhelming if that is all you read.
Coral Schaffer at enamelworksupply.com translated the process to the
smaller size and simpler procedures that I have been using for
jewelry size pieces of metal and her detailed instructions make the
product very easy to use. She sells a small piece and sends along the
