A Photographic Study Of Movement Of Material On A Web Offset Press Blanket, Leigh Stewart
Theses
This paper studies the movement of material which accumulates on the image printing blanket of a web offset press printing newsprint. A theory is advanced to explain this movement. It is based on the differences in velocities of the paper and blanket surfaces entering and exiting the printing nip. The designed experiment run uses three factors to test the changes in direction and rate of movement. These are: (1) the compressibility of blanket sets, (2) the relative image printing and impression blanket diameters, and (3) the printing squeeze. No other factors involved in the nip area are tested. The movement …

A Method Of Determining Dot Sharpness Of Lithographic Films, Timmy Mccreary
Theses
Two methods were attempted to determine an objective evaluation of lithographic films with respect to the sharpness of half-tone dots produced by the films. In Method I a step function target was placed in contact with a continuous wedge and a film sample. After exposure and development, a curve of the film was drawn in terms of per cent transmission versus log exposure. Since the input (target) is a step function, the output (curve) should also be a step function. It was expected that the width of the step in the curve would yield some measure of how well the …
