Color lithography is a complex process, and identifying the root cause of printing failures can be quite challenging. One common issue that often arises is the potential damage or "smashing" of the printing rubber roller. Understanding why this happens and how to prevent it is essential for maintaining print quality and efficiency.
Dongguan Haichang Hardware & Rubber Co., Ltd., established in 2001, has been a leading manufacturer of industrial rubber rollers and printing machinery components. With a strong technical foundation, advanced machinery, and a commitment to quality, the company has built a solid reputation in the industry. Focused on customer satisfaction, they prioritize quality, professionalism, and thoughtful service. Their mission is to deliver reliable products and support that meet the highest standards.
When it comes to printing issues, many problems are not directly related to the rubber roller itself. However, when a problem does occur with the ink or water roller, several factors could be at play:
1. **Water and Ink Imbalance**: If the ink roller is not working properly, it may be due to an improper balance between water and ink. This is usually not a problem with the roller itself but rather with the settings.
2. **Sticky Water Roller**: A sticky water roller might be caused by incorrect ink distribution, poor hydrophilic properties of the roller, or a dirty surface. If the roller works fine when new, it's likely not the rubber's fault.
3. **Hard Ink Roller**: If the ink roller is too hard (typically above HS50), it can lead to streaks or "bars" on the printed material, especially on solid areas.
4. **Hard Water Roller**: Similarly, a water roller that is too firm can cause uneven water distribution, leading to issues like water shortage or unstable supply, which can result in "bars" on the final print.
5. **Unexpected Damage**: Even under normal operation, rubber rollers have a limited lifespan. If they break before that, it's considered unexpected damage. This can happen due to cracked bearings, excessive friction, or mechanical issues such as burrs on chrome-plated rollers or peeling surfaces. Another common cause is "dry grinding," where the ink or water roller runs without proper lubrication, causing rapid wear. This often occurs when operators neglect to protect idle sections of multi-color presses, leaving them running without ink or water.
By understanding these common causes, printers can better diagnose and prevent issues, ensuring smoother operations and higher-quality output. For more information, visit: [http://news.chinawj.com.cn](http://news.chinawj.com.cn)
