Printing rollers can usually be divided into the following types:
Feed rubber roller: responsible for transferring ink from the ink tray to the printing plate
Imprinting roller: Transfer ink from the layout to paper or other materials
Adjusting the rubber roller: Adjusting the thickness and uniformity of the ink layer
Cleaning rubber rollers: cleaning residual ink on the layout material quality
Common rubber roller materials include:
Rubber: Strong wear resistance, can withstand large pressures
Silicone: Smooth surface, easy to clean
Polyurethane: Good flexibility, suitable for different printing materials
Metal: High hardness, can withstand high temperatures performance index
The key indicators that affect the performance of rubber rollers include:
Surface hardness: determines its wear resistance and embossing effect
