Rotogravure printing, more often known as gravure printing, is an advanced and versatile form of intaglio printing. The quality and consistency of prints it produces, especially for large-volume tasks, are unrivalled. Central to its functionality is the printing cylinder, the heart of the rotogravure printing system.

Proper maintenance and efficient use of this component can greatly enhance your system’s performance and longevity. In this article, we will discuss five best hacks to maximize your rotogravure printing cylinder performance.

Proper Cylinder Cleaning and Maintenance

Regular cleaning of the printing cylinder is key to its peak performance. Over time, ink residues, dust, and other contaminants can accumulate on the surface of the cylinder. This buildup can interfere with the engraved cells’ capacity to hold ink and, in turn, the print quality. To clean the cylinder, use a soft, non-abrasive cloth and a suitable cleaning agent that won’t damage the cylinder material.

Accurate Cylinder Engraving

Each cell on the cylinder needs to be accurately engraved to hold the correct amount of ink. Modern engraving techniques, like electronic engraving, can provide a high level of accuracy and repeatability. If the cells are too deep, they will hold excess ink and cause blotting on the print. On the other hand, if they are too shallow, the print will appear faded. Thus, maintaining optimal engraving depths is vital to maximize the performance of your rotogravure printing cylinder.

Regularly Replace Doctor Blades

Regularly replacing the doctor blade will ensure that it’s always in optimal condition. Moreover, the right blade pressure is crucial. Too much pressure can wear out the blade and cylinder faster, while too little pressure can leave excess ink on the cylinder.

Correct Storage of Cylinders

Storage conditions for the cylinders can greatly affect their performance and lifespan. Cylinders should be stored in a clean, dry environment to prevent rusting and other forms of degradation. It’s also vital to store them in a way that doesn’t expose them to physical damage, such as scratches or dents.

Invest in High-Quality Inks

The quality of the ink used in rotogravure printing can significantly affect the cylinder’s performance and the overall print quality. High-quality inks provide consistent color, dry faster, and are less likely to cause buildup on the cylinder surface.
