There are three different methods for gravure cylinder cleaning - manual cleaning with solvents, automated cleaning with solvents, and automated cleaning with non-solvents.
Manual cleaning with solvents
While manual cleaning has been a traditional method in the printing industry, its limitations are hard to ignore, especially when dealing with gravure cylinder cleaning. The use of heavy cylinders and tools can lead to inconsistent cleaning results, particularly evident in gravure roll cleaning. The removal of built-up ink at the end face of the cylinder becomes even more challenging, making it necessary to add additional mechanical tools. This method not only poses health and safety risks to employees but also tends to become a bottleneck in production due to limited capacity.
Automated cleaning with solvents
Automated cleaning systems using solvents offer a more efficient alternative to manual cleaning, addressing the challenges associated with gravure cylinder cleaning. These systems ensure a constant and effective cleaning flow, capable of handling various ink types for high-quality results. However, the handling of solvents still introduces health and safety concerns, and the system requires a dedicated ATEX room. Despite the larger start-up investment, the long-term benefits include lower quality costs and increased production output.
Automated cleaning with non-solvents
Automated systems using non-solvents are an excellent choice, particularly for gravure roll cleaning. This environmentally friendly alternative offers the same high-quality cleaning without the need for an ATEX room. Placed conveniently next to the printing press, these systems not only enhance working conditions but also open up new possibilities for cylinder logistics, reducing the need for heavy manual handling.
