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.
