Disclosed is a compressible printing blanket in which voids are formed in the compressible layer by using microballoons, comprising at least two fabric layers, an adhesive layer interposed between adjacent fabric layers, a surface rubber layer, and a compressible layer arranged between the at least two fabric layers and the surface rubber layer and containing spherical voids and voids having a shape other than a sphere in a ratio defined in formula given below: <?in-line-formulae description="In-line Formulae" end="lead"?>S<SUB>1</SUB>:S<SUB>2</SUB>=20:80 to 95:5 (1)<?in-line-formulae description="In-line Formulae" end="tail"?> where, S<SUB>1 </SUB>denotes the number of spherical voids per unit area in a cross section of the compressible layer, and S<SUB>2 </SUB>denotes the number of voids having a shape other than a sphere per unit area in a cross section of the compressible layer.
