Summary:PURPOSE: A multi-layered silicon blanket for a micro-pattern offset printing is provided to extend the lifetime of the blanket, and the printability during an offset printing by including a first layer with the improved adhesive property, and a second layer with the improved mechanical property. CONSTITUTION: A multi-layered silicon blanket for a micro-pattern offset printing comprises the following: a first layer containing 50~90wt% of polysiloxane mixed with high vinyl polysiloxane and low vinyl polysiloxane in a ratio of 0.5:1~2:1, and 10~50 parts of silicon gum by weight for 100 parts of polysiloxane by weight; and a second layer containing 50~90wt% of polysiloxane mixed with high vinyl polysiloxane and low vinyl polysiloxane in a ratio of 2:1~15:1.
