Patent attributes
A printing blanket is designed to have less sink-down, less variation in thickness along with time, less susceptible to temperature or moisture, and which employs woven fabric having excellent measurement stability, thereby having a sufficient durability against variation in thickness in high-speed printing. The printing rubber blanket includes a surface rubber layer, and at least two fabric layers, in which at least one of the fabric layers other than that located adjacent to the surface rubber layer is woven fabric made of a yarn of No. 10 count or less but No. 6 count or more used for warps of the woven fabric, and a yarn of No. 30 count or less but No. 20 count or more used for wefts of the woven fabric, and the woven fabric is subjected to a stretching process in which the woven fabric is expanded in the warp direction.
