Abstract
The Diffusion Transfer Process is now widely used in the Graphic Arts industry, and it is important to determine to what length different factors affect the optimum use of it. The effects of exposure, age of the processing solution, and line frequently on the image quality of the Kodak PMT system were studied. Exposure was varied by exposing the material to a standard illuminance for different amounts of time; the processing solution was aged by bubbling air through it for varied amounts of time; line frequency was varied by using a Kodak sinusoidal target and examining the images of two different frequencies. Data was obtained from microdensitometer traces of the images produced and statistically analyzed to determine the significance of the factors involved. It was found that line frequency was the most signficant factor, followed by exposure and finally by the age of the processing solution. The interaction of line frequency and age of the processing solution was also found to be statistically significant.
