In silk screen printing, every single color is a process. With each color, printed through one frame. The silk screen printing process is repeated for each color selected for the given product and repeated until the visual expression is achieved according to the design of the product. To secure the rightful color combinations, a spectral photometer is used. For example, if your membrane keyboard needs to match the colors of your enclosure, we can measure the enclosure and thereby customize the membrane keyboard colors to match your enclosure. The photometer also allows us to measure a given material and put it in as a filter, so we create the best conditions for being able to meet your color wishes. This applies to both Pantone, RAL and NCS colors.
The material on which the color is printed depends on the application environment of the finished control panel. It is of paramount importance with the right choice of material that considerations must be made for the foil's user environment. On materials used for front foils and membrane keyboards, the printing is made on the back of the selected material. This means that the color resistance and durability are endless and that it can be cleaned with most cleaning agents. Furthermore, in the silk screen printing process, the conductor paths included in a membrane keyboard are printed. These are printed with a conductive silver paste material.
