Process Optimization of Make-Ready Time in Offset Printing for Higher Operational Efficiency

Abstract

 Make-ready time is a key factor in determining turnaround time, production cost, and overall operational efficiency in the offset printing sector. The objective of this study is to find possibilities for optimization by providing a thorough examination of the make-ready time in an offset printing machine. Ink setting, paper alignment, registration, colour matching, blanket and roller washing, plate mounting, and other common make-ready tasks are reviewed to enhance the efficiency in offset printing. With the assistance of skilled staff, real-time data has been collected from an established printing company. Two widely used offset printing machines, KBA RAPIDA 106 and Heidelberg SM 105 are chosen to measure the make-ready times for various printing jobs. After analysis, findings indicate that registration stability and colour calibration are the most persistent barriers to achieving consistent make-ready performance throughout the ten jobs analysed on both machines. These results highlight the potential of minimizing the overall make-ready time, which would improve press utilization, minimize material wastage, and increase overall production.
