Abstract
Provided is a method for manufacturing a sleeve printing plate capable of forming an image pattern which applies printing on an object to be printed by laser engraving without generating cracks and chippings in a printing plate made of a photosensitive resin. The method for manufacturing a sleeve printing plate by making a printing plate made of a photosensitive resin surround an outer peripheral surface of a circular cylindrical sleeve body and forming an image pattern on the printing plate by laser engraving includes the steps of: washing and cooling the printing plate with water; applying heating treatment to the printing plate at a predetermined temperature; and applying heat radiation treatment to the printing plate after the heating treatment.
Claims6
A method for manufacturing a sleeve printing plate, the method comprising:
- washing and cooling a printing plate made of a photosensitive resin with water after the printing plate is subjected to an irradiation of an ultraviolet ray, wherein the printing plate is a sheet-shaped plate;
- applying a heating treatment to the printing plate by a hot air in an oven at a temperature of 135 to 170° C. after the washing and cooling;
- applying a heat dissipation treatment to the printing plate after the heating treatment;
- disposing the printing plate to surround an outer peripheral surface of a circular cylindrical sleeve body;
- and
- forming an image pattern on the printing plate disposed on the circular cylindrical sleeve body by laser engraving,
- wherein the heating treatment and the heat dissipation treatment are performed while holding the printing plate in a circular cylindrical shape having a diameter approximately equal to a diameter of the printing plate in a state where the printing plate is mounted on a laser engraving device or a printing device, and
- wherein the laser engraving is carried out after the washing and cooling, the heating treatment, and the heat dissipation treatment.
A method for manufacturing a sleeve printing plate, comprising:
- forming a printing plate made of a photosensitive resin into a circular cylindrical shape and subjecting the printing plate to an irradiation of an ultraviolet ray so as to cure the photosensitive resin;
- washing and cooling the printing plate with water after the irradiation of the ultraviolet ray;
- applying a heating treatment to the printing plate by a hot air in an oven at a temperature of 135 to 170° C. after the washing and cooling;
- applying a heat dissipation treatment to the printing plate after the heating treatment;
- disposing the printing plate to surround an outer peripheral surface of a circular cylindrical sleeve body;
- and
- forming an image pattern on the printing plate disposed on the circular cylindrical sleeve body by laser engraving,
- wherein the heating treatment and the heat dissipation treatment are performed while holding the printing plate in the circular cylindrical shape having a diameter approximately equal to a diameter of the printing plate in a state where the printing plate is mounted on a laser engraving device or a printing device, and
- wherein the laser engraving is carried out after the washing and cooling, the heating treatment, and the heat dissipation treatment.
