PROBLEM TO BE SOLVED: To display an excellent paper discharging property without spoiling the halftone dot reproducibility and the ink transfer property by a method wherein on the surface of a surface printing layer which is provided on a supporting body layer, protruding parts of a specified uneven difference, comprising a rubber grain which has a high elasticity and is excellent in ink transfer property, are provided. SOLUTION: For a supporting body layer 12 of a blanket 10 for printing, a plurality of base fabrics 13 wherein a woven fabric or a non-woven fabric such as cotton, a polyester, or rayon, a rubber glue is soaked, are laminated by inserting a compressive layer 14 as required. Also, between a surface printing layer 11 and the compressive layer 14, a base fabric 13 may be provided as a reinforcing layer. Then, for the rubber which constitutes the surface printing layer 11, rubber which is excellent in oil resistance and ink transfer property such as NBR, chloroprene rubber, is used, and on the surface, protruding parts 15 comprising a rubber grain which has a high elasticity and is excellent in ink transfer property, are formed, and the height of the unevenness is made 8-15μm, and the proturding parts deform when a paper for printing is pressed, and thus, a pushing back force strongly works, and a favorable paper discharging property is displayed.
