About this document
Non-Toxic Carbon Printing with Agar by PabloMartinez is a document available to read on EtoBox.
This document proposes a non-toxic alternative to dichromate sensitizer for carbon printing using iron-based photopolymerization. The traditional dichromate sensitizer is highly toxic. The proposed method uses ferrous ions that are exposed to light and form a latent image. This is then developed with hydrogen peroxide, producing hydroxyl radicals that initiate polymerization of the gelatin emulsion. The main challenge is oxygen inhibition, but this is addressed by using an agar agar overlayer that blocks ox
