Electroplating has solved many production problems in printing. Much experimental work has been done to determine the best metal and method of electro deposition for each application to give the desired results. The applications of electroplating in printing machinery and printing surfaces for letter press, gravure and lithography are discussed with emphasis on the practical results obtained. In lithography, electroplating has produced improvements in printing plates, ink rollers and drums, water rollers, and miscellaneous equipment on sheet and web fed presses. These improvements are discussed together with necessary precautions.
