Novel Chemistry for Use in Graphic Arts.

Recent progress in chemistry, especially in inorganic chemistry, could possibly lead to many improvements in the graphic arts. To illustrate how such progress might be utilized in approaching the solution of practical problems, a detailed discussion is given of old and new photographic processes against the background of some of the new knowledge. Nonsilver halide, dry development, and lamp-developable colloid and photopolymer processes are reviewed. In the second part of the paper, some aspects of other graphic arts processes that seem to invite the application of recently uncovered chemical products, processes, and techniques are more briefly illustrated. These include problems in the wear of metals, the preparation and conditioning of metal surfaces, the improvement of lithographic platemaking and printing, and the acceleration of ink drying for higher-speed press operation.
