Ciśnienie i docisk oraz szerokość strefy kontaktu między cylindrami i wałkami w drukującej maszynie offsetowej – przegląd literatury

The printing literature provides different values of pressure between cylinders in the printing unit and between rollers in the ink unit of the offset printing machine. Very often there is no information on whether a given value of pressure is maximum or average. Another frequent problem referred to in the printing literature is that authors do not reveal the source of theorems, equations or other important information. This article includes a set of values collected for pressure, line pressure, press clamping and the contact zone width that have been presented by other authors in their specific articles and books. It also includes definitions of pressure, line pressure, press clamping, indentation of blanket and metric clamping. In addition, the article briefly presents findings of the experimental research related to the contact zone between cylinders and rollers was carried out in the printing unit and in the ink unit until present. This article also gives publication references which provide for different equations concerned with the clamping force of cylinders, their compression or indentation, the contact zone width and the impact the specific stress-strain has on blankets.
