Offset machine operation is a critical process in the printing industry, involving several meticulous steps to ensure high-quality results. Initially, the machine is prepared by collecting job information and setting up the machine according to this data. The inking unit is controlled by measuring pH levels, roller hardness, and adjusting the roller gap to regulate ink supply. The feeding unit is then prepared by setting the sucker and blower, adjusting guides, and maintaining the feed board height. Sheet control involves setting various lays, measuring paper thickness, and adjusting the double sheet detector. Plates and blankets are cleaned, prepared, and preserved to ensure quality. During the printing process, the press is made ready, run for production, and cleaned as needed, with strict control over print registration for multi-color jobs. Safety measures are followed meticulously, raw materials are handled carefully, and management plays a crucial role in accident prevention. Finally, the delivery unit is set up by adjusting guides and maintaining the delivery chain gripper. Detailed record-keeping throughout these steps is essential for consistent and high-quality printing outcomes.
