MANUFACTURING METHOD FOR INTAGLIO, INTAGLIO AND PRINTING METHOD USING INTAGLIO AS WELL AS PRINTED MATTER

摘要

PROBLEM TO BE SOLVED: To ensure that an intaglio with a sharp edge of a recessed part can be obtained by an etching process facilitating the formation of a pattern and is free from the limitation to the use application to printing and enhances the printing reliability. SOLUTION: An internally mixing type two-fluid nozzle is used atomizing an etching solution into fine droplets by a high pressure gas and the atomized etching solution droplets are injected from the nozzle to perform the etching process. An externally mixing type two-fluid nozzle is used atomizing an etching solution flow injected by the high pressure gas and the atomized etching solution droplets are injected from the nozzle to perform the etching process.
