1. During the printing process, if the printed sheet is smaller than the length of the rubber surface, there may be areas without ink or ink accumulation at both ends of the rubber roller. If there is no ink, it can cause dry wear on the rubber surface at both ends, leading to a rough surface. During operation, ink oil should be used to keep both ends of the rubber surface lubricated. If ink accumulation occurs at both ends, it should be cleaned promptly when stopping; otherwise, it will dry and form hard ink blocks. When operating again, the pressing of hard ink blocks can damage the rubber surface, causing roughness and flaking.

    2. It is best to use a dedicated cleaning agent for cleaning the rubber roller. If conditions do not allow, 90# gasoline can be used for cleaning, but only soft cloths should be used to wipe with gasoline, and the rubber roller should not be soaked in gasoline for a long time, as this can cause corrosion to the rubber roller. Wiping with gasoline for a short time will evaporate and will not cause significant damage to the rubber surface.

    3. UV ink rubber rollers must use a dedicated cleaning agent for UV ink.

    4. Alcohol dampening rollers must use a dedicated cleaning agent for alcohol dampening rollers.
    It is advisable to choose alcohol dampening rollers produced by regular manufacturers. If self-formulated, "soft water" should be used and the appropriate pH value should be maintained, generally controlled between 4.5-6, and should not exceed the standard to avoid affecting the lifespan of the rubber roller.

    5. Nylon rollers are used as ink transfer rollers by various printing machine manufacturers and users due to their excellent ink transfer properties and high wear resistance. Since nylon rollers are prone to breakage from impacts and strong external forces, special attention should be paid to avoid bumps and scratches during handling.
