    • A process for imparting a simulated patina appearance to a copper substrate, and a substrate having that appearance. A colorant having the desired initial patina color tone is employed to produce a non-continuous layer of colorant on the surface of a copper substrate by roll coating. The appearance of patination of the desired tone is created by interspersed spots of colorant with the remaining portion of the substrate being exposed for natural patination. The interspersed spots of colorant may be produced by screen printing, by spattering, as by spraying, or by mechanical removal of colorant after application to the substrate surface, or a combination.
    • 将模拟的铜皮外观赋予铜基板的方法以及具有该外观的基板。 采用具有期望的初始色调色调的着色剂通过辊涂在铜基材的表面上产生不连续的着色剂层。 所需色调的观察的外观是通过着色剂的散布点产生的,其余部分的基底被曝光以进行自然染色。 着色剂的散斑可以通过丝网印刷,溅射,喷涂或通过在施加到基材表面上之后机械去除着色剂或组合来生产。

The appearance of patination of the desired tone is created by interspersed spots of colorant with the remaining portion of the substrate being exposed for natural patination. The interspersed spots of colorant may be produced by screen printing, by spattering, as by spraying, or by mechanical removal of colorant after application to the substrate surface, or a combination. The colorant is preferably a paint and may be applied by non-uniform spraying on the substrate surface. Non-uniformity may be accomplished by varying the volume of colorant sprayed during the application process or by varying the relative movement of the spray and substrate. After application, the colorant provides a simulated patina to the copper substrate surface while allowing the remaining (non-covered) portion of the substrate to patinate naturally.
