Puretch description

Puretch is a biodegradeable, negative working dry film photopolymer. It has the highest resolution possible with a dry film; the thinner the film the higher the resolution.

It is easy to use with non-industrial techniques and is available in quantities ideal for the DIYers.

Puretch Instructions ~ Troubleshooting Tips

Developer is not included with film. 100% Sodium Carbonate is the developer and can be bought by the half pound on the products page.

Negative Working Photopolymer means that areas of copper that are not exposed and covered with a black line will etch away, leaving the circuit path in the clear areas of the art work. Make sure you prepare art accordingly. This may require inverting the black and white before printing transparencies.
