Rollers

Ink rollers play a key role in the printing process by applying ink uniformly and precisely to the printing plate, enabling the subsequent transfer of ink to printing blankets and the respective material during printing.

It is important to use high quality rollers to ensure that the ink is pre-released correctly and transportation through the inking unit is optimal. This contributes to increased stability in the printing process.

Dampening rollers are designed to distribute water-based wetting evenly over the surface of the printing plates. This allows the printing plates to attract ink on the desired areas and repel ink on the non-printed areas. This is an important process for achieving sharp and precise printing results.

Dampening is an integral part of the offset printing process, where the printing plates are water-receptive and ink-repellent in the areas that are not to be printed. Proper wetting ensures that these areas remain moist and clean, maintaining print quality and preventing unwanted impressions.

Pinch rollers, also known as nip rolls, play an important role in various industries and processes, including printing, paper production, textile industry and more. Nip rollers ensure that the material passes through a precisely defined path or is processed in a precise way. They can control pressure, speed, tightness and heating of the material depending on the process and purpose of use.

For example, pinch rollers can be used to create a carefully controlled pressure on the printing sheet, ensuring that the ink is properly transferred to the paper. In the textile industry, pinch rollers are used to control the pull and stretch of the fabric during different stages of production.

The composition and setting of the pinch roller varies depending on the specific application and industry in which they are used.

Lacquer rollers or anilox rollers are cylindrical rollers, often made ceramic or metal, used for applying coating or surface treatments to printed materials.

These rollers play an important role in coating and finishing printed matter, ensuring an even and smooth distribution of coating on the surface.

The purpose of coating is to improve the appearance, protection and durability of printed materials. coating can add gloss, matte or silk finishes, enhance color printing and protect printed materials from moisture, dirt and abrasion. These rollers are designed to ensure an even and uniform application of coating, which is essential to achieve the desired aesthetic quality and protection.

When the primary rollers in a machine become worn or need maintenance, replacement rollers can be ordered to ensure production continues uninterrupted. This is important to maintain efficiency and production speed in an industrial or manufacturing context.

Replacement rollers can be identical to the primary rollers or specially designed to suit the machine's requirements.

Retreading refers to the process of "re-cladding" a used roller.

The process of retreading involves replacing the outer, worn layer of the roller with a new rubber layer. This may be necessary when the rubber wears out, gets damaged or becomes ineffective over time. By

By performing retreading, the performance and quality of the roller is improved, contributing to better print quality and precision in the printing process.

Retreading used rollers leads to both cost savings and more environmentally friendly production by recycling rather than buying complete new rollers.
