The Influence Of Press Variables And The Measurement Of Show Through Of Paper, William Nourse
The Influence Of Press Variables And The Measurement Of Show Through Of Paper, William Nourse
Theses
Several fundamental questions are discussed relating to show through of ink on paper. These questions relate to (a) the significance of ink and press variables in regard to show through; (bj the correlation between the light reflectivity of an ink film thickness and the show through of the ink; (c) the correlation between the percentage of pigment in the ink, and the show through of ink; (d) the interchangeability of various instruments for the measurement of show through. Data is obtained using a standard offset ink in combination with several different kinds of paper. Several, different known ink film thicknesses …
A Study To Assess The Aesthetic And Economic Viability Of Producing Original Fine Art Prints And Autographic Artists Books On A Rotary Offset Press, And An Introduction To A New Medium For Creating And Producing Original Fine Art Prints And Autographic Artists Books, Daniel Richard Tucker
Theses
This study investigates factors which the author believes could contribute to the determination of the aesthetic and economic viability of producing original fine art prints and artists books on a rotary offset press using direct imaged, uncoated lithographic plates. It also introduces a new medium for the creation and production of these works which was developed during this study. This investigation has been accomplished in the following ways: First, answers were sought to ten questions the author believed any artist considering the use of a rotary offset press as a means of producing these works would want to know. The …
A Quantitative Method Of Pre-Setting The Ink Distribution Keys Of An Offset Duplicator Using A Photoelectric Estimating Unit, Martin Marino
A Quantitative Method Of Pre-Setting The Ink Distribution Keys Of An Offset Duplicator Using A Photoelectric Estimating Unit, Martin Marino
Theses
The purpose of this study was to study the feasibility of quantitatively pre-setting the ink key distribution on an off-set press. Presently the pre-settings of the ink keys has been left to the pressmens' ability and experience. This, in many cases, involves much "trial and error" work along with lengthy makeready times. This study attempted to reduce makeready time by quantitatively pre-setting ink keys from data obtained from an estimating unit and use of a set of calibration curves. A photoelectric estimating unit was designed and constructed to read integrated densities of copy to be printed. There was one reading …
An Investigation Into The Emulsification And Determination Of Water In Lithographic Ink Emulsions, Thomas Saczawa
An Investigation Into The Emulsification And Determination Of Water In Lithographic Ink Emulsions, Thomas Saczawa
Theses
A study of the emulsification process of lithographic ink and water was conducted to investigate methods for determining the water content of lithographic ink and water emulsions. Experiments using infra-red spectroscopy and analysis of the hydroxyl and carbonyl absorption bands revealed several variables which must be considered when attempting to use infra-red spectroscopic methods for the determination of the water content of ink emulsions. These factors include the choice of pigment, (either transparent or opaque), the type of cell medium, and methods for dispersing added water into an ink. The initial problem encountered was a lack of reproducibility when attempting …
