Zusammenfassung:	A printing plate material for direct plate making includes an aluminum base material, a hydrophilic layer provided on the base material, and a dot control layer provided on the hydrophilic layer and having a critical surface tension equal to or lower than a surface tension of the image forming liquid. An image forming liquid is discharged from an inkjet recording head onto the printing plate material for direct plate making and is hardened. Thereby, a direct-made printing plate is obtained.
