In the printing industry, where production never stops, it is very important to continuously maintain machine performance. If a machine breaks down, the production will stop and it will disturb the production process. Therefore, the maintenance system must be managed efficiently to solve those problems. The paper presents the study results on continuous quality improvement of offset printing using preventive maintenance features. Offset printing is a process that involves a multitude of variables, independent and interdependent factors. The offset printing process was analyzed and the factors that have a significant influence on the quality of the process and the products made were identified. The defects that may occur during the printing process and the causes thereof have also been identified and the types of non-conformities of the end products were estabilished. The experimental method was used. The case study was conducted on Manroland 508. For the planning of preventive maintenance activities, the duration of the maintenance works necessary to ensure the proper functioning of the offset printing machines was established. Finally, maintenance activities that would guarantee and continuously improve the quality of the printing processes and the printed products were issued.
The paper analyses 4 printing technological flow cases, considering the author’s experience (over 15 years) in the printing industry to improve the production efficiency. The productivity, the quality and the delivery time are the main areas of interest for people working in the printing & finishing industry, where the print demand structure evolved and the costs of replacing machines are very high. The implementation of the organisational and reconfiguration of machines changes contribute to the development of new efficient working structures within the printing process, therefore increasing the efficiency of it, as one can notice from the diagrams presented in the paper. The time and the costs presented have been obtained through a couple of trials of modifying the work parameters, the colour and the materials according to the colour management guidelines in use. Ultimately the optimal technological structure has been chosen for quality improvement, cost and delivery time reduction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
