The printing pressure in this context refers to the force applied between the water roller and the printing plate, the plate cylinder and the printing plate, as well as the blanket cylinder and the printing plate. If a printing unit shows reduced durability of the printing plate—such as when it only lasts for 100,000 impressions or even fewer—the graphic areas may start to wear out prematurely. In such cases, it's important to check whether the issue is related to the printing pressure in any of these areas. Each component should be inspected systematically to identify and resolve the problem.
If there is a noticeable strip of wear along the axial direction of the cylinder during printing, it’s highly likely that the printing pressure is the main cause. Therefore, checking and adjusting the pressure should be one of the first steps in troubleshooting.
In addition, regular inspection of the printing pressure should be part of the daily maintenance routine for the printing press. This helps ensure consistent print quality and prevents unexpected downtime. By maintaining proper pressure settings, the machine can run smoothly and efficiently, supporting the overall production process.
