Abstract
A metal layer cleared by contact with a chemical clearing agent to reveal an underlying graphics layer is at least partially covered by a buffer material that delays contact with the clearing agent. The buffer material can be applied in a pattern that forms a temporary image in the metal layer prior to more completely revealing the underlying graphics layer.
