Properties of lithographic printing plate

(1)Moderate grain

Multilayered complex grain structure is formed on the surface of substrate through electrolysis graining and a series of chemical and electric-chemical methods. The formed grains are fine and full and could reach the multilayered structure to a great degree, which ensures more excellent dot reproduction and quicker ink-water balance of lithographic printing plate.

(2)High resolution

Special ingredients, together with the optimally distributed formular weight of the binding of polymers in the coating of lithographic printing plate offer fine dots with sharp edges and reproduce images with rich tone.

(3)Long run length

Specially selected colophony in the coating of lithographic printing plate significantly increases the press life of the plates.

(4)Excellent hydrophilicity

Hydrophilic treatment is adopted on the basis of oxidization. By this process, quick ink-water balance of lithographic printing plate are abtained.

(5)Excellent chemical resistance

Unique coating recipe offers excellent durability and chemical resistance

(6)Image visibility after exposure

Sharp color change after exposure, making it easier to check the image.

(7)Air eduction layer

Electrostatic spray technique is adopted during the production, which helps keep better contact between films and plates. Therefore, shorter vacuuming time and better exposure of flat meshwork of lithographic printing plate are achieved
