Sažetak

In order to achieve high-quality colour prints by using an electrophotography printing machine, it is necessary to prepare the printing substrate. Additional treatment may be needed to achieve the better substrate surface tension for optimally attaching the liquid electrophotography ink to the fine art paper. To ensure good adhesion of the ink to the printing substrate, a pre-treatment by application of surface tension regulating fluids (priming) may be used. In this paper, we will determine the possibility of realization of the CMY prints and the possibility of achieving an increased range of tone value in electrophotography digital printing. Based on the results, the new possible values of reproduced CMY tones will be determined so that a higher print quality can be achieved. The application of primers changes the optical properties of the paper printing substrate, which directly affects the colour reproduction. An additional 100 % increase of primer application will result in total colour changes of ΔEC (0,5g/m2 & 1g/m2) = 0,06, ΔEM (0,5g/m2 & 1g/m2) = 0,42, ΔEY (0,5g/m2 & 1g/m2) = 0,08. In this scenario, 1 g/m2 application of primer will produce the most intense full tones and therefore the highest quality prints for all three ElectroInk process colours.
