Finish - Metal Business Cards
Brushed or dull polished metal is metal with a unidirectional satin finish. It is produced by polishing the metal with a 120–180 grit belt or wheel then softening with an 80–120 grit greaseless compound or a medium non-woven abrasive belt or pad.
Blasting is one way to achieve frosted look. You can also try a mass finishing using ceramic media if you have greater quantity; however, on softer metal, the appearance will be more of a galvanize appearance rather than frosted. Sand blasting is the best way to achieve FROSTED finish on the metal.
Chemical etching is the technique used to precision-etch custom artwork into the metalcard surface. The process uses acid to etch away unwanted metal, while a photographically prepared mask (Phototool) is used to protect the metal areas that are to remain after the etching process. The etching process occurs before the card is copper plated and the finished effect is a darkened debossed imprint.
Screen Printing Color
One colour is printed at a time, so several screens can be used to produce a multi-coloured image or design. There are various terms used for what is essentially the same technique. Traditionally, the process was called screen printing or silkscreen printing because silk was used in the process.
Cutting Out Finish
The chemical etching process is used to etch into the same position on the front and back of the card surface. When the two areas come into contact, the piece will fall out creating a unique and visually stimulating cut through effect.
