BLANKET FOR OFFSET PRINTING AND MANUFACTURING METHOD THEREFOR

摘要

The present invention relates to a blanket for offset printing and a manufacturing method therefor. The blanket for offset printing according to the present invention comprises a cushion layer, a support layer, and at least two surface printing layers, wherein said at least two surface printing layers include silicon-based resins which have mutually different values with respect to at least one value among a hardness value, a value of fluorine content and a value of silicon oil content. Since the blanket for offset printing according to the present invention comprises surface printing layers formed in two or more layers, the surface printing layers are not easily swollen by ink, so that the process waiting time is reduced, and the process margin is improved.
