摘要:
A very simple and easy method for preparing dry planographic printing plates having a high printing performance and durability in the absence of dampening water is proposed. The method comprises the steps of (a) coating one surface of substrate which is transparent to ultraviolet light with an uncured photocurable silicone, (b) bringing the thus coated surface into direct contact with a surface of a base plate to form a laminate, (c) overlaying the other surface of the substrate in direct contact with an original transparency bearing an image pattern which is opaque to ultraviolet light, (d) irradiating the laminate with ultraviolet light from above the transparency and (e) separating the substrate from the base plate to allow a portion of the photocured silicone coating to transfer to the surface of the base plate, and a portion of the uncured silicone coating to stay in situ on the surface of the substrate.
