摘要：This article describes the quality of flexographic printing machines for corrugated cardboard printing. The influence of the factors on which the quality of the final product depends is analyzed. Technological properties of printing equipment are characterized by purpose indicators, which determine its technological capabilities, as well as functional indicators, which include the parameters of the technological process and features of its passage. For sheet flexographic printing machines for corrugated cardboard printing, technological possibilities are revealed through the type and parameters of the original production, the nature of consumables. Inturn, they can affect not only the parameters of the process, but also determine the technological scheme of the machine and its components.In this study, the systematization of factors influencing the technological properties of flexographic printing press was carried out.In complex systems and machines, the requirements for the nomenclature of indicators and their values are set both for the machine (or line) as a whole and for its individual parts, units and units. The values of the output parameters of the machine depend on the parameters that characterize the state of their individual parts and units, as well as their role in ensuring the programmed quality indicators of the machine as a whole.In order to obtain a good quality imprint, it is important that in the printing process the balance between the adhesion to the surface (wetting of the contacting surfaces) and the cohesion (separation of thei nk layer) must ensure that the ink layer is split in hal fand does not change during the print run. This process is essentially dependent on the speed of separation of the ink layer after the voltage drop and the deformation properties of the materials in the contact zone.For flexographic printing, the magnitude of cohesion is small because the ink is thin. Optimal condition for ensuring printing contact is the transition of the ink from the form to the printed material under constant pressure.The systematization of the print quality indexes on the modern corrugated cardboard packaging was also carried out, which determines the design features of the construction of printing machines of sheet flexographic printing machines.
