Abstract: An exterior decor panel for a home appliance includes a metal sheet having a first surface and a second surface opposite the first surface. The metal sheet includes a first patterned portion having successive recesses formed in the first surface, where each of the successive recesses have a prescribed depth, and a second patterned portion having successive protrusions formed at the second surface, where the successive protrusions correspond to the successive recesses. The successive recesses are formed by applying a force to the first surface, thereby transferring the force to the second surface to form the successive protrusions

Abstract: Manufacturing an exterior decor panel for a home appliance includes laminating a photosensitive dry film on a front surface of a metal sheet, the photosensitive dry film having a higher etch resistance than the metal sheet against an electrolytic solution, photo-masking the photosensitive dry film attached to the metal sheet to create a pattern having a minimum width of 0.1 mm in the photosensitive dry film to thereby expose the front surface of the metal sheet corresponding to the pattern in the photosensitive film, electrolytic-polishing the photo-masked metal sheet by dipping the photo-masked metal sheet in an electrolytic bath to allow the electrolytic solution to contact the exposed front surface of the metal sheet and form the pattern in the front surface of the metal sheet, and performing post-treatment on the metal sheet, the post-treatment including washing and removing the photosensitive dry film.
