Method for forming plate characters in a half-tone gravure platemaking process

---

Abstract

---

A method for forming plate characters in a half-tone gravure platemaking process wherein the laser beam is moved so that it will be irradiated on a light sensitive material for forming a plate character on the light-sensitive material by exposure. The plate character is made with a frame portion and a filling portion. The frame portion is formed with continuous groove-form cells which have a predetermined length and width and dot-form projections are formed in the groove-form cells for preventing ink flow. The filling portion is formed by dot-form cells which have a shadow-portion dot percentage.
