Photo Etching technology is an ultra-precision processing technology with the highest level of precision. It is a high-tech processing technology of materials that covers metal surfaces with sensitized materials, and separates areas that receive ultra violet rays and areas do not, in order to corrode metals. Products of eX-Series add fine lines and angles on stainless steel and glass to maximize gradation effects. Also using patterned metal as a mold and imprints the image on the base film using photo etching technologies. Various processes applied to imprinting film in order to maximize the diffused reflection effect of patterns.
