Optimization of passive activator parameters for printing machines

Abstract

This paper is devoted to the mathematical calculation and experimental researching of ink apparatus using in printing machines. We show the existence of structuring process in ink boxes and the formation of so-called quasi-solid in the printing ink. Our geometric model is based on the mathematical problem of covering some planar domains by the set of circles. All circles belong to one-parameter family and it is a special feature of the problem. Using this model we get the method of calculation some optimal dimensions of passive activators using for destruction the quasi-solid. Calculations are based on experimental data and it is achieved by variation of several parameters. In this paper we describe the system with only one passive activator but there exist the opportunity to optimize the system with several ones. Software realization is not given in the paper but it is based on the algorithms that are described. Experimental data were received with using real equipments and materials of printing industry. Specifically, we investigated the generating of quasi-solids in the ink boxes and we got some results for using the passive activators.
