Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for reshaping a graphics on a printing plate which has been used for printing, the method being improved in a background technique and being capable of suppressing a time cost, a material cost and an economic cost low particularly concerning deletion of the graphics which has been used for printing.SOLUTION: The whole of the base plate 5b of the printing plate 5a is washed to remove ink or lacquer. The whole of the base plate 5b is subjected to grinding treatment to delete the preceding print graphics. The graphics part of the base plate 5b is partly treated with a pulsed laser beam to image-form the succeeding print graphics and partly form a nanoscope hydrophobic surface structure of a nano scope. The whole of the base plate 5b is treated with a hydrophilicity-improving agent 7 to partly hydrophilize the graphics part of the base plate 5b which is hydrophobic immediately before.
