Three-dimensional effect printing method

Abstract

A three-dimensional effect printing method includes steps of providing a housing including a transparent substrate; printing an uneven transparent texture layer to form a textured pattern on an inner surface of the transparent substrate opposite to an outer surface facing a viewer; drying the transparent texture layer; printing a colored texture layer on the transparent texture layer; and drying the colored texture layer.

What is claimed is: 
     
         1 . A three-dimensional effect printing method comprising:
 providing a housing comprising a transparent substrate;   forming an uneven transparent texture layer on an inner surface of the transparent substrate opposite to an outer surface facing a viewer using a printing process, the transparent texture layer having a textured pattern;   drying the transparent texture layer;   forming a colored texture layer on the transparent texture layer using a printing process; and   drying the colored texture layer.   
     
     
         2 . The printing method as described in  claim 1 , wherein the transparent substrate is made of transparent resin. 
     
     
         3 . The printing method as described in  claim 1 , wherein the transparent texture layer is formed from transparent ink and the colored texture layer is formed from colored ink. 
     
     
         4 . The printing method as described in  claim 1 , wherein drying the transparent texture layer comprises placing the housing with the transparent texture layer in a chamber and heating the housing with the transparent texture layer at a constant temperature of about 40 degrees Celsius for 10 hours. 
     
     
         5 . The printing method as described in  claim 1 , wherein drying the colored texture layer comprises placing the housing with the colored texture layer in a chamber and heating the housing with the colored texture layer at a constant temperature of about 40 degrees Celsius for 10 hours.
