PRINTING METHOD FOR PERFORMING REAL-PICTURE PRINTING OPERATION ON ADVERTISING BOARD BY MELTING PARTIALLY BASIC COATING LAYER, FORMING INK STORAGE LAYER, AND PRINTING DESIGN THEREIN

摘要

PURPOSE: A printing method for performing a real-picture printing operation is provided to improve durability and prevent abrasion by melting partially a basic coating layer to form an ink storage layer and printing the design within the ink storage layer. CONSTITUTION: A basic coating layer is formed on a reflective face of a reflective sheet(50). Ink is injected to the basic coating layer to melt a part of the basic coating layer and form an ink storage layer(60). A design is formed on the reflective face by implanting the ink into the ink storage layer(70). A protective film is adhered on each surface of the basic coating layer and the design(80). The design is not projected from a surface of the basic coating layer.
