A crisp picture on a flexible package doesn’t just appear. The printing system behind the perfect colour, sleek surface and uniform ink is one that has a role for each of its elements. Though the rubber rollers are not necessarily the most visible components of a gravure printing machine, they can significantly impact the final print.
The selection of the right roller is more important as the printing lines are getting faster and customer demands are getting reliable in quality.
What Is Gravure Printing?
Gravure printing refers to a printing method in which an engraved cylinder presses ink against a material to be printed (substrate), which can be plastic film, paper or another material used for packaging. The tiny engraved cells on the cylinder are filled with ink and a doctor blade scrapes off any excess ink on the surface. The substrate is subsequently brought in contact with the cylinder and the image is transferred.
The process is supported by rubber rollers which provide further guidance or pushing of the material and ensure appropriate contact depending on the machine design.
How Rubber Rollers Support Printing Performance
1. Maintaining Smooth Material Movement
The material used in flexible packaging should be able to travel along the machine in a controlled manner. This can be made possible by using the right roller specification, which ensures that the film moves smoothly. When this does not happen, then the web moves with difficulty.
2. Supporting Consistent Print Quality
It’s vital that there is a uniform contact between the substrate and printing cylinder to get reliable results. The dimension and condition of the rollers, the hardness and alignment can affect the consistency of the material going through the printing area. Proper use of a Gravure Printing Rubber Roller will help to ensure stable operation and minimize variations caused by poor roller condition.
3. Helping Production Run Efficiently
Delays may impact deliveries and have an impact on operating expenses. Periodic roller inspection and correct specification can help to detect any wear in a timely fashion before it is a larger issue.
4. Matching the Needs of the Application
All gravure machines and substrates don’t require the same substrates. The kinds of right roller are chosen based on machine dimension, operating speed, machine material, working environment and required surface characters.
What to Consider When Selecting a Rubber Roller
Before purchasing a Gravure Printing Rubber Roller, check the specifications of your machine and the conditions in the production line. Consider what diameters, face lengths, hardness, surface finish, and material suitability for your rollers are needed. Proper installation and regular maintenance of the Gravure Printing Rubber Rollers are equally as important.
