dc.description.abstract For many years the printing industry, specifically sheetfed offset and letterpress printers, have been dealing with the problem of chemical ghosting. Traditionally it has been, a problem associated with drying oil inks. More recent research concludes that ghosting is also affected by the permeability of an adjacent substrate. This thesis examines paper coating constituents, their degree of concentration, and what influence they play- with regards to ghosting. A quickset drying oil ink has been found which when subjected to the proper laboratory conditions will display a high degree of colored ghosting. The thesis indicates the method of creating ghosting and a method of measurement. A procedure for making paper samples with various percentages of coating constituents is outlined. Experimentation has shown ghosting to be affected by the absorbency and ink hold out of the paper coating. This effect is increased at low absorption levels but diminishes as absorption is increased. In addition, comprehensive background information is included to assist the reader to become more enlightened to the true nature of this problem. The list of subjects surveyed include the definition of ghosting, the mechanisms involved, associated variables, and a summary of all pertinent literature. en_US
