Used to develop photopolymer films such as ImagOn and Puretch.

The ink flows smoothly onto plastic film and dries quickly. The red colored ink blocks a remarkable amount ultra violet light, as it is on the opposite end of the spectrum. The pen is recommended, for hand drawing, or touch ups on digital positive and negative film separations.

Non-Toxic Etching Ground

Photopolymer film that is adhered to a piece of plastic such as the polycarbonate or PETG plates.  You will need a U.V. (ultra violet) light source to expose this film.

The thinnest dry film (.6mil) photoresist available which yields the highest resolution etchable resist.  For best results use with copper plate and ferric chloride.
