WATERLESS OFFSET ORIGINAL PLATE MANUFACTURING METHOD AND MANUFACTURING APPARATUS

Japanese Patent JP2023149453

A

To provide a manufacturing method and apparatus in which a peelable film has the high coatability with respect to a substrate while using a material of an easy-to-peel film for the peelable film for substrate reproduction in a step of manufacturing a waterless offset original plate of a columnar substrate, which can perform stable printing and can manufacture a high-quality original plate.SOLUTION: A manufacturing method includes: a first application step of discharging droplets of a peelable film material from a first applicator to a peripheral surface of a columnar substrate while rotating a shaft of the columnar substrate as the central shaft by using a peelable material with a specific physical property, and forming a coating film by laminating the peelable film materials by making the first applicator reciprocate in the axial direction of the columnar substrate while spraying the droplets of the peelable film material to the surface of the columnar substrate; a step of forming a peelable film on the columnar substrate by performing solidification of the peelable film material applied onto the columnar substrate; and a second application step of discharging a silicone film material from a second applicator and applying the silicone film material to the surface of the peelable film.SELECTED DRAWING: Figure 1
