Multiple colour acid etching on 304 SS

++++

Hi,

I am redesigning an intercom panel which is currently a 3mm thick 304 stainless steel panel, powder coated white, blue paint filled acid etching, with a clear anti-graffiti coating. We are looking to increase the number of colours from just blue, to red and blue. The two colours are mostly separated except one area where they meet. This meeting can be separated by a non-etched area if required. I would appreciate guidance in the best methods to employ to achieve this result. panel size: 200mm x 200mm quantity: approx. 50 units details: ~ speaker, mic and button holes ~ weldstuds on rear.

In appreciation of your time,
