Photo Etching Processing
Photo Etching is an alternative way to form custom logos, and all the etched logos will be shallowly recessed or etched through with open areas. Except for lapel pins, photo etching is widely used in brass bookmarks, Christmas hanging ornaments, a nameplate for plaque, and metallic business name cards…. The brass plate is the best material for photo etching; however, stainless steel and aluminum plates are available for acid etching. The depth of etched logos can be varied by controlling etching time, shallow recessed or etched through as empty holes are all feasible according to your artworks.
The process is transferring the logo from a film to a sheet of metal, then acid-etched, clean up the acids and other impurities, hand-fill soft enamel colors to recessed area of the pins, then baked at temperature of 160 degrees centigrade. An optional epoxy coating can be added to top of pins to keep the colors from fading and cracking, also have smooth surface of pins.
