Seeks info on electroforming watch dial markers

.

Dear Sir,

In electroforming flat objects, I have a raw information that the metal substrate is specially textured, I guess it is for the ease of removal.

What specific metal is most suitable for this process? This metal substrate is then coated with photo sensitive coating and the image has to be transferred by a UV light exposure. After rinsing off excess photo resist, an electro deposition process will take place on the unmasked surface. What is the current density required if the product is about 1 inch diameter?

The purpose of my research is to acquire a technology of making the watch dial hour marker(gold and nickel) through electroforming. In our application after removing the product from the substrate, the bottom portion is sprayed with adhesive ready to stick on the watch dial face.

Thanks and looking forward for your prompt advice.
