According to the printing process, the type of sensitizer applied in the of PS plate is divided into positive type and negative type. The positive type is printed down with the positive original, to make the positive PS plate for printing on the machine; the negative type is printed down with the negative original, to make the negative PS plate for printing on the machine.
PS printing plate has high resolution, full dot reproduction, rich levels, and ink balance easy to master, stable performance, fast sensitivity, large development latitude, high printing resistance etc characteristics.
