Quality Of Electrophotographic Prints On Foil Substrates

Abstract

Electrophotographic printing uses many types of substrates, our study focuses on plastic substrates. Six types ofregular and self-adhesive foil substrates were chosen to be printed using two electrophotographic presses: XeroxColour 1000 Press and Canon imagePress C7000VP. A test chart containing tone value scales and a set of samplesfor profiling was created, spectrophotomety and densitometry was applied to obtain the optical and colorimetricproperties of the substrates investigated. Xerox Color 1000 Press produced larger densities and tone value increaseon every type of substrate. The largest TVI values and reproducible colour gamut was observed on the smoothestfoil in case of both presses. Large colour differences were found between patches of full tone process colors on thedifferent substrates investigated.
