The article solves the problem of the information technology development for offset machine ink printing systems analysis. For this reason an ink printing system mathematical model has been created that describes the process of ink flows circulation and imprints reproduction in three-dimensional image. The model displays the work of ink feeding n-zone unit that provides a discrete ink supply. The process of ink transferring in each zone is presented by k ink microflows, each of which is described by z-transformation equations. The work of oscillation cylinders is mathematically described which perform a complex movement, because simultaneously with the rotation they are engaged in axial reciprocating movement. The printing plate image is described by form printing elements operators. Based on the mathematical model of ink printing system a simulator in Matlab Simulink environment has been constructed, which makes it possible to conduct research of ink distribution and transmission in such systems, taking into account the technological disturbances and determining the ink layer thickness at any point of ink printing system.

Keywords: ink printing system, ink feeding unit, oscillation cylinder, form rollers, ink microflows, signal graph, three-dimensional model, ink rolling and transfer processes.
