Method for manufacturing a master mold which is used to form a micropatterned film applied to an exterior of a household appliance and manufacturing apparatus and method of the film using the master mold
An apparatus and a method of manufacturing a micropatterned film are disclosed. More particularly, a method for manufacturing a master mold capable of forming a micropattern on a film applied to an exterior of a household appliance, an apparatus and a method for production of a micropatterned film using the above master mold, and appliances having such micropatterned films attached thereto are disclosed. The method for manufacturing a master mold used for forming a micropatterned film applied to an exterior of a household appliance includes, applying photoresist (110) to a surface of an STS substrate (100) and UV irradating the same through a patterned mask (140) to transfer the pattern of the mask (140) to the substrate (100), etching the STS substrate (100) to which the pattern has been transferred removing the photoresist (110) from the etched STS substrate (100), and reproducing the pattern of the STS substrate on a synthetic resin substrate (210).
