The present invention provides a manufacturing method of a compressible printing layer, comprising a vulcanizing step comprising a first heating process in which one surface of a compressible printing layer including an unvulcanized compressible layer containing microcapsules is heated by bringing the one surface of the compressible printing layer into contact with the surface of at least one heated metal roll while applying tension to the compressible printing layer, and a second heating process in which the other surface of the compressible printing layer is heated by bringing the other surface of the compressible printing layer into contact with the surface of at least one heated metal roll while applying tension to the compressible printing layer.

Manufacturing method of compressible printing layer and manufacturing method of blanket for printing

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:S:S=20:80 to 95:5 &#x2003;&#x2003;(1)where, Sdenotes the number of spherical voids per unit area in a cross section of the compressible layer, and Sdenotes the number of voids having a shape other than a sphere per unit area in a cross section of the compressible layer.
