OPTICAL PROPERTIES OF PRINTED TRANSPARENT SUBSTRATES.

This paper provides an analysis conducted by means of expanded Murray- Davies model on a transparent substrate which was printed with solvent-based ink and UV ink. The research is based on empirical methods developed using the model (extended Murray-Davies equation derived from the Yule-Nielson model) to define the printed pattern on a substrate in order to improve the quality of reproduction in halftone imaging. Applicability of these equations, developed for research of media such as paper, was examined on a transparent substrate. Model contains two empirically derived parameters "w" and "v", whose determination are based on data from microscopic images. Spectroscopic results were obtained by quantitative spectrometer built with a digital camera. [ABSTRACT FROM AUTHOR]
