What are the contact-printers mentioned in Kodak publication G10 for the discontinued Azo papers and where can I buy one? I have copied and pasted some of this below. EXPOSURE Contact printers generally have a very high level of illumination. In order to keep exposure times within reason, contact printing papers, such as AZO Paper, are made with a relatively low speed. Therefore, its not practical to use contact papers with an enlarger as a light source. A contact printer is a glass-top box with exposing lights and a safelight inside, and hinged pressure cover over the glass. Switches control the lights that allow different intensities to various parts of the image.
