A method for forming plate characters in a half-tone gravure platemaking process being characterized in that a laser beam moved so that the laser beam is intermittently irradiated onto a light sensitive material and a plate character is formed on the light-sensitive material by exposure. The character thus formed is made up with a character frame portion and a character fill portion surrounded by the character frame portion, the character frame portion being formed by a plurality of intermittently arranged groove-form cells each having a predetermined length and a width which can prevent flow of ink when ink is applied by wiping the plate surface with a doctor, and the character fill portion being formed by dot-form cells which have a shadow-portion dot percentage.
