Research into the influence of Speed on essential Factors in Web-Fed Gravure Printing

By the research programme 'Investigations into the effect of speed on important printing process factors in rotogravure presses,' the Institut für Druckmaschinen und Druckverfahren (Institute for Printing Machines and Printing Processes), Darmstadt, proposes to solve important problems arising from the tendencies towards an increase in machine speed and automation in rotary gravure printing. Above all, the results will provide the designer with data for the optimum dimensioning of important parts and the most advantageous design of different units. In addition, by investigating various disruptive factors in the printing process, pointers towards eliminating or favourably influencing them can be obtained. A specially developed experimental printing unit with numerous test possibilities is available; this unit also meets the requirements involved in the actual production process. It is designed for a maximum speed of 30000 r.p.h. and has two plate cylinders of 550 mm (21 +~ in) and 1 100 mm (43 in) circumference.
