ResumoIn an engraving rotogravure printing machines the print cylinder (ink unit) and the impression cylinder are interaction in an ink or print substrate. The contact Surfaces comprise a metal surface and a rubber impression roller surface. it is the appears from findings based on the working in the “Aero Plast Pvt. Ltd” and experience of people working in printing houses the issue of interactive between ink rollers and printing cylinders in an rotogravure printing machine is of great importance. It has impact on the quality of printouts, consumption of energy, time of making, The printing machine ready for operation, wear of the machine’s components and related consumables like ink, flexible substrate, impression cylinder and engraving cylinder. During the theoretical studies, since the transfer takes place by a series of three phases such as inking, doctoring and printing, the ink transfer ratio. Moreover, the relationship in between the interaction b/w gravure, ink or ink roller to the substrate was subject to experimental attempts aimed at verification of the interaction mechanism presented. In order to measure the rollers compression a clock sensor was used, and for measurement of the contact area width – a device called Roller Nip Control. The results of these measurements are presented in this paper and are compared with the results obtained from the equation derived in the course of theoretical studies using the analytical method.
