Rubber Roller RYOBI 680 750 920 Transfer Roller Plate Inking Roller

Product Description

RYOBI printing machine transfer roller is mainly responsible for transferring ink from the upper ink roller to the printing plate roller, ensuring that the ink can evenly cover the surface of the printing plate.

It is one of the key transmission components in offset printing machines and is crucial for ensuring the final printing quality.
Maintenance and replacement:

As the usage time increases, the rubber surface of the transfer roller will wear or be damaged, and it needs to be replaced regularly.

It is recommended to use XINBAO RUBBER Roller to ensure a perfect match with the machine and optimal performance.

The rubber type and hardness of the printing rubber roller are very important for different printing methods, and different printing requirements have different mechanical and chemical standards.

For most ordinary printing, the hardness of the printing rubber roller can reflect the quality of the rubber to a certain extent. If the hardness is too high, its corrosion resistance may be enhanced to a certain extent,

However, the ability to carry water and ink decreases, and the wear and tear on the printing machine and the graphics and text of the PS version increase. If the hardness is too small, the service life of the rubber roller may be too short due to poor compressive and corrosion resistance. For the hardness requirements of printing rollers: On the premise of ensuring good water and ink filling ability, as well as sufficient resistance to chemical corrosion and physical effects, the hardness of printing rollers should be appropriately reduced. Currently, XINBAO is providing printing machines for RYOBI 680 750 920 ,The hardness standard for the rubber rollers of ordinary ink printing machines is Shore A 28.

In practical printing applications, selecting the appropriate glue type can first avoid printing quality failures caused by the inappropriate role of the glue roller itself, ensuring stable and smooth printing.

Material: The rubber material used should have excellent abrasion resistance, resilience, and chemical resistance to withstand the demands of high-speed printing. Nitrile rubber (NBR) and polyurethane (PU) are commonly used materials due to their durability and ink compatibility.
