Abstract

One of the main methods for protecting paper banknotes is intaglio printing, whose key quality factor is the durability of the printing plate. This study investigates the process that induces the stressed-strained state of an engraved printing plate obtained by direct laser engraving with different geometric parameters of printing and non-printing elements of printing plate. The task addressed relates to the lack of understanding of the mechanism behind the influence of geometric engraving parameters on the stress concentration and deformation of engraved elements of intaglio printing plates. This causes their premature wear and a decrease in the stability of the printing process.

Based on modelling the contact interaction of the plate and printing cylinders, the results of the study have established quantitative dependences between the geometric parameters of engraving and the values of equivalent stresses and deformations of engraved strokes. It was found that the stress values vary within the range of 15–550 MPa, and the deformations range from 0.01 to 0.06 mm, depending on the characteristic zone of the engraved elements and their geometric parameters. The optimal geometric parameters of engraving have been determined based on the analysis of simulation results.

A notable feature of the results is that the model accounted for the actual printing conditions during intaglio printing, as well as the presence or absence of paint within the stroke. Compiled recommendations for the selection of geometric parameters of engraved strokes could be taken into consideration when designing the engraving of intaglio printing plates. The results of this study are valuable for the industrial production of banknote products and securities
