Room-light processes like SelectaColor and FA-1 Sensitizer require a full-size transparency. The simplest method is to make one with an injket printer or laser copier plus transparency film. Start with any kind of original-- a black & white print, color print, color slide, book illustration, etc. Scan or photo-copy it, and print with black ink onto transparency film. In use, the film is held in contact with the sensitized surface while exposing with a bright light such as a high power halogen bulb.(Alternate methods: You can take the artwork to any office supply store like Kinko's and order a black & white transparency. Or you can make a transparency photographically by traditional darkroom methods.)Set of 10 sheets transparency film, size 8 1/2x11 inches:
