Commonly used printing roller use and characteristics

The printing industry rubber roller is the collective name of a series of printing rollers, including: ink roller, washing roller, alcohol roller, uniform ink roller, pressure roller, pressure roller, carton printing roller, suction roller and so on. Different roles of the printing roller, use, characteristics, hardness is not the same.

Ink roller: It is used for the transportation of ink coatings. The general hardness is 30~35(A). This kind of rubber roller needs to have oil resistance, high elasticity and even ink property. Washing roller: The printing roller can only be washed with water. Roller hardness is generally 25 to 28 (A), usually requires water resistance, high elasticity, uniform ink characteristics; alcohol roller: that can be washed with alcohol printing roller, hardness range 20 ~ 25 (A), this type of plastic The roller requires the characteristics of uniform ink, high elasticity, and chemical resistance. Uniform ink roller: Stir the ink to make it uniform in the printing. The hardness requirement is 75~80(A). This type of roller needs to have wear resistance. High resistance to oil, chemical resistance, and high surface finish; Pressure roller: For printing paper, hardness 60~85(A). This kind of rubber roller usually needs wear resistance, high elasticity, and anti-static property. Compression roller: used for printing plastic film, hardness 60 ~ 85 (A), this type of roller needs wear, high elasticity, anti-static; suction roller: mainly used for conveying printed paper, hardness is usually 25 ~ Between 40(A), high elasticity, high coefficient of friction; carton printing roller: this kind of rubber roller is used for packaging carton Printing, with hardness between 60 and 85 (A), requires wear resistance, oil resistance and high elasticity.
