Machine Downtime: Causes and Optimization Strategies in Web-fed Offset Printing Press Organizations: A Case Study of "dainik Bhaskar Press", Hisar

Objective of this paper is to investigate major causes of machine downtime in Web-fed Offset Press Organizations and hence find out the best optimization strategies for downtime. Web-fed offset is a type of offset printing in which a continuous roll of paper is fed through the printing press. Even very high speed presses upto 75000 IPH have come to exist with full automation, still machine downtime is a strong point of concern among most of printers. Machine downtime is a period of time that a system fails to provide or perform its primary function and machine stops causing reduced efficiency of machine. The downtime data was collected on daily basis in consecutive three months February, March and April in Dainik Bhaskar Printing Press, Hisar. The results clearly indicated that downtime is caused mainly due to reel change and web break. Power failure, reel shaft puncture, operational mistakes, folder knife problem and web wrap around blanket are unperiodic and less prone still important factors to be considered by most of the printers.
