Abstract
No-conventional printing or “digital printing” is newer technique where instead of usual printing model the digital representing is done by the use of RAM from the computer, which also leads the printing process. The no-conventional printing techniques are electrographic, ink-jet, thermographic, ionic printing and others. The properties of the printing substrate change with differences of the data transmission and digital printing or they become specific.Printing orientation to digital printing techniques means the use of new valuation methodology of surface properties and interactions between paper surface and printing inks, toners or colours. Interactions are caused by the change of surface charge of the printing substrate, which activates the surface and make it possible to electrostatic bonding of single components from the printing inks or toners. Mechanisms of the interactions base on surface charge neutralization by adsorption of opposite charged ion from the printing ink or colour. The rate of adsorption and stabilization of the printing ink or colour is determined by the properties as surface charge, capillarity and appropriate penetration ability in to the printing substrate structure. Research hypothesis is the study of the effect of added agents into the coating colours and their migrations in the treated paper surface that affect the surface charge and the study of the printing quality. The knowledge of the interaction mechanisms is connected with the optimisation of the base paper production and optimisation of the paper surface properties that affect the quality of the printing and print impression, made in “digital printing” techniques. The main goal of the research project is the determination of the valuation methodology of the printing substrate quality as well as printing quality used for high quality printings, printed in no-conventional printing techniques.
