The problem of this experiment is to determine which of three factors; sulfite level, bromine level, and development time, affect the image spreading during the infectious development of a graphic arts film. Three different levels of each factor will be studied. The method used consists of measuring the distance between two fine edges on a test target. This test target is then contact printed onto the graphic arts film. The distance between the two fine edges on the graphic arts film is then measured. Any difference between the two distances will be the result of image spreading. It is these distance differences that are used as the response in the three level, three factor Yates analysis. The sulfite level has been found to be a significant factor. The conclusion is that the sulfite concentration affects the image spreading during the infectious development of graphic arts film, but not bromine level or development time. The film tested was Kodak Kodalith Ortho, Type 3.
