I can get my hands on a Chromalin proofing machine, the kind that exposes contacts with a kind of blueish light. If you have seen this process done before, you'll know what I am talking about. The lamp is in a rectangular device and on top there is a glass where the film/chromalin sandwich is placed. The cover is closed and an exposure is made (the whole thing works like a sophisticated contact printer). I am not sure whether the lamp is producing UV frequencies. If it is, I could use it for alt photo processes, such as gum and platinum. Does anyone know if it would work ?
