Printing roller Rod

The printing roller is a key component of the ink transfer system in printing machines, consisting of a metal core wrapped with a rubber layer. It transfers ink through the elastic deformation of its surface and utilizes the adhesive properties of the rubber to evenly transfer images and text. It is used in the ink path systems of offset and gravure printing machines to control ink thickness and ensure uniform coverage.
Selection
When selecting, consider the compatibility of the printing machine model with the roller diameter. Choose nitrile rubber or silicone material based on the ink type. Inspect the surface smoothness and hardness value, observe the bonding strength between the rubber layer and the metal core, evaluate wear resistance and solvent resistance, and determine dynamic balance requirements in conjunction with the equipment's operating speed.
