PRINTING METHOD FOR GLASS FORMING 3D -IRREGULAR REFLECTION

摘要

PURPOSE: A glass printing method for forming three-dimensional irregular reflection is provided to vary the reflectivity of light according to viewpoints by applying a screen printing technique based on a three-dimensional pattern with respect to the surface of a transparent or opaque glass. CONSTITUTION: A glass printing method for forming three-dimensional irregular reflection includes the following: A transparent or opaque glass is washed and dried. A three-dimensional pattern is screen-printed on the upper surface(101) of the transparent or opaque glass using inorganic ink(20). Color layers(30, 40) are formed on the lower surface(102) of the glass. In the screen-printing process, a distance between the glass and a net screen of 100 to 400 meshes is between 2 and 20mm. The angle of a squeegee is between 30 and 45 degrees. The pressurized intensity of the squeegee is between 0.3 and 0.4kg/cm^2.
