In printing using a printing plate material using a plastic as a support, the printing position stability, the ink deposition property at the time of printing, and the printing durability are improved. In a printing method in which an underplate sheet material is interposed between a printing plate material having at least a hydrophilic layer, an image-forming functional layer and a backcoat layer on a plastic support, and a plate cylinder of a printing machine, the underplate A printing method, wherein a coefficient of dynamic friction between the surface of the sheet material and the surface of the backing layer side of the printing plate material is 0.1 to 0.5.
