| There are two reasons for color change in films. One is that there are different colors for film compounds. Second is that the wavelength of visible light is reflected, bent and absorbed, which reflects different complimentary colors and makes color change. Therefore, using reactive gas thickness to adjust the composition of the film will cause color change. Changing the thickness of the film for half-transparent films and one can get different film colors. Catcher uses vacuum sputter technology to apply Cr, Ti and other metals and by changing the thickness of the reaction gas to get different nitride or carbonate nitride films, we developed more than a dozen films, such as black series, brown series, gold series, silver series and others (see below). Recently, in combination with anodizing or Ti anodizing, we anodized Ti film and created oxidized Ti film with varying thicknesses using different processing conditions to develop more colors. |

| Color of coating is basically determined by chemical composition of the coating. By using different target materials and with various concentration of reactive gas, coatings, such as nitrides or carbon-nitride, with different colors can be produced by vacuum sputtering technology. In the meanwhile, color can be determined by the thickness for a semi-transparent film. Catcher develops a technology which has more color diversity than traditional vacuum sputtering technology. By combine the vacuum sputtering and anodizing technology, titanium anodizing coloring can be done on metal parts. The color diversity is achieved by adjust the thickness of anodizing titanium coating on metal parts. |
