METHOD OF ELECTRONICALLY PRINTING A HARDENED ALUMINIUM MATERIAL, CAPABLE OF ENHANCING THE COMPETITIVENESS OF PRODUCT BY BUILDING A PRODUCTION SYSTEM MAKING IT POSSIBLE TO PRODUCE VARIOUS KINDS OF PRODUCT IN SMALL QUANTITY

摘要

PURPOSE: A method of electronically printing a hardened aluminium material is provided to produce high-quality product which expresses various color impression of image beyond the limit of metallic colors and has excellent reliability on corrosion resistance and weather proof property.;CONSTITUTION: A method of electronically printing a hardened aluminium material is as follows. The aluminum alloy material finished a grinding/planarization process is anodized to create a porous coating layer. The ink is injected into the porous coating layer of the anodized aluminum alloy material through inkjet printing. The surface of the aluminum alloy material is colored. The porous coating layer of the aluminum alloy material into which the ink is inserted is sealed. The sealed aluminum alloy material is polished.;COPYRIGHT KIPO 2010
