Computer Simulation and Control of the Rotogravure Press System.

A mathematical model of the tension-register relationships in the rotogravure press was developed and programmed first into an analog and then into a digital computer simulation of dynamic disturbances and their effects has proven to be a valuable tool in the evaluation of actual press recordings and for prediction of press control behavior. The model is described and some typical simulations of dynamic tension and register shifts are shown. Plans for use of the model in the development of fully integrated computerized press controls are outlined. the development of fully integrated computerized press controls are outlined.
