method for manufacturing cooking apparatus with image layer using surface step

摘要

PURPOSE: A manufacturing method of cooker in which 3d image diagram enteric layer using a surface step is formed are provided to provide natural three dimensional perception and novel aesthetic appreciation by showing natural and consecutive differences and changes. CONSTITUTION: A manufacturing method of cooker in which 3d image diagram enteric layer using a surface step comprises the following steps: manufacturing a cooker body(10) in which a step side is projected by a fixed pattern on the exterior surface; forming a background color layer having first color on the exterior surface of the cooker body; spraying second color from a fixed slope angle to the faced side of a step side(20) based on a line perpendicular to the exterior surface of the cooker body; performing the partial painting in which the second paint is partially sunk and spread at light density; and forming three dimensional image diagram enteric layer visually classified by the gray level difference which is painted on the step side.
