| 摘要 |
The invention relates to a process for producing a front plate (26) for a control-related, touch-sensitive operating panel (5), which front plate (26) comprises mineral glass or acrylic glass and is intended for structural superposition with respect to a graphic output means. Here, haptically perceivable, raised markings (28) are formed on the front plate (26) for identifying and/or delimiting at least one partial region of the front plate (26) provided as a touch-sensitive input surface (29). The haptically perceivable, raised markings (28) are produced here by being imprinted, wherein for the time being a first layer of a first synthetic resin coating material, in particular with optimized adhesion to mineral glass or acrylic glass, is applied to the mineral glass or acrylic glass. Then, at least one further layer of a second synthetic resin coating material, in particular with optimized toughness, hardness and/or chemical resistance, is applied by at least partial overprinting of the first layer. The invention furthermore relates to a correspondingly produced front plate (26) and to an operating panel (5) equipped with such a front plate (26). |
