The company understands that the success of any printing process depends largely on the proper installation, maintenance, and adjustment of printing rubber rollers. Whether working with letterpress, gravure, flexo, or offset presses, the correct handling of these components is crucial for achieving high-quality results and extending the life of the printing equipment.
**Installation and Adjustment of Printing Rubber Rollers**
Proper installation of printing rubber rollers is essential to ensure smooth operation and optimal performance. It should always be done by trained technicians who understand the specific requirements of each printing machine. The roller must be properly aligned and in close contact with both the ink roller and the printing plate. For example, in letterpress printing, the height of the printing roller is typically set at 3.14mm, matching the type height, while the PS plate is lower at around 1.2mm. Knowing these specifications helps achieve accurate pressure settings and consistent print quality.
Lubrication of bearings and shafts is equally important. Before installation, the outer surfaces of the rubber bearings and sleeves should be coated with lubricating oil to reduce friction and wear during operation. Neglecting this step can lead to premature wear, frequent bearing replacements, and even damage to the roller structure.
**Printing Roller Debugging**
Debugging the printing roller is a critical process that directly affects print quality and equipment longevity. Proper pressure between the water and ink rollers must be maintained. If the pressure is too light, it may result in poor ink or water transfer, while excessive pressure increases friction, causing heat buildup, accelerated aging, and potential damage to the rollers.
When printing text, the height of the rubber roller should be slightly lower than the printing plate to avoid excessive pressure and reduce wear. Adjustments should be made using a calibration roller before printing begins. This allows the operator to check the ink distribution and ensure the roller remains stable during high-speed operations.
**Common Issues from Improper Adjustment**
Failing to properly adjust the rubber roller can lead to several problems, such as:
- Surface damage and debris accumulation, causing blurred or broken text.
- Inconsistent ink coverage, resulting in missing colors or uneven prints.
- Over-tightening of the roller, which can cause mechanical failure and costly repairs.
By following best practices and maintaining attention to detail, users can maximize the lifespan of their printing equipment and ensure consistent, high-quality output. At Dongguan Haichang, we are committed to providing reliable products and expert guidance to support your printing needs.
