A Framework for Optimised Design of Serrations on a Printing Gripper.

Abstract

Serrations on a printing gripper, significant for ensuring the register accuracy in sheet-fed offset printing machines, have to sustain severe contact stresses. Poorly designed serrations can have an adverse effect on its life and performance. However, literature on the design of serrations on a gripper is scarce. In this study, using analytical solutions, we have developed an optimization framework that can help to quickly arrive at design solutions to maximize the durability and performance of a serrated printing gripper. Although the analysis is done in the context of printing grippers, it provides a methodology for development of design optimization frameworks for similar grippers.
