Skyba V. Regularity of print run stability of monometallic forms elements of offset printing

The thesis is devoted to complex research and printing of intermediate elements printed forms to establish patterns of impact parameters to guide their quality indicators to stabilize the printing process and prediction of lottery money monometalevyh forms a flat offset printing with moisture. The effect on the stability of the intermediate elements Tirage monometalevyh forms of composition, structure and surface microgeometry, characterized by accumulation, redistribution and reduction elements technological environment printing a contact in the surface layers. The relation between the thickness of oxide film on the surface of the intermediate elements, size and intensity of moisture in the process of printing, which is characterized by a decrease in mass fraction of aluminum ions on the surface under the influence of active components of printing inks. The mathematical model of lottery stability plates as described and calculated regression equation with the input controlling parameters: the value of concentration of the oxide films, surface roughness and printing intermediate elements farbospryynyattya factor. A new formulation of additives to the hybrid offset printing inks and wetting solution. A technology user "process operation monometalevyh plates flat offset printing with moisture."
