The article solves the problem of developing a two-dimensional mathematical model of ink printing system of small format offset machine. The description of ink transfer by all elements of ink printing system has been realized by z-transformation. The mathematical model reflects the work of ink feeding n-zone unit that provides a regulated ink supply on the ink printing system entrance. The transfer of ink in each zone is represented by k micro flows, each of which is described by corresponding system of equations. Oscillating cylinders working mode was mathematically described, one of which is in contact with the transmission roller of ink printing system, and two others - with form rollers. Form image that creates a load for ink printing system is set by using the printing elements forming operator. The developed model describes in detail functioning of ink printing system elements and enables research and analysis processes of ink distribution and transmission in such systems and determination the ink layer thickness at any imprint point and at each element surface of ink printing system.
Keywords: ink printing system, two-dimensional model, ink micro flows, signal graph, ink feeding unit, oscillation cylinder, form rollers, ink rolling and transfer processes.
