Color quality, paper effect

Leekley RM, Tyler RF, Hultman D. (1978) Effect of paper on color quality of prints. Tappi J 61(10) 108-111. 

The particular colors that are observed at different angles will depend critically on the thickness of the thin film coating. Precision instrumentation is required to carefully control film thickness during production. The magnitude of the optical effect depends on the density of flakes in the ink, while the quality of the optical effect depends on the precise orientation or alignment of these flakes with respect to the paper surface. 

Since ink jet technology has not yet been used for high quality color reproduction, the objectives of this process must be considered in terms of the materials limitations of ink jet printing. When a color reproduction is made by a mechanical process, much time is spent matching different dyes and papers with the desired effect wanted. After the materials decision is made,... 

T he preceding papers have discussed the effects of carbohydrates, especially sugars, in a number of types of food products. The functions considered were largely those of a chemical, physical, or mechanical nature such as will affect the color, texture, flavor, and other qualities of the numerous kinds of foods of which sugars are an essential ingredient.
