Abstract

Digital printing presses are getting the attention of the printing industry for its numerous benefits over the conventional printing techniques. Under the digital printing process, dry toner-based electrophotography technology is considered as a mature form of printing while comparing with the inkjet technologies. These presses are known for improved colour gamut reproducibility characteristics also, and most the prospective print consumers demand for high colour gamut for enhanced colour reproduction. Paper plays an important role, while discussing the colour gamut print quality factor and moreover the surface characteristics of paper is the utmost concern in this context. In this research work, the surface properties of various kinds of non-ISO papers have been studied and is related with the colour gamut while printing in a multi colour electrophotography digital printing press.
