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 …
