Disclosed is a printing plate material comprising a substrate and a component
layer provided thereon, the substrate having a center line average surface roughness
Ra of from 0.2 to 1.0 m, and an oil-retention volume A2 of from 1
to 10, wherein the center line average surface roughness Ra is obtained from three
dimension surface roughness measurement according to JIS-B-0601, and wherein an
image is capable of being recorded on the component layer by imagewise exposure
of infrared laser.
