Security feature in graphic documents

摘要

A printing system receives a graphic document having a security area. The graphic document identifies a secure color to print in the security area. The graphic document is converted for printing by a printing engine of the printing system. This converting substitutes a secure patterned color in place of the secure color. The specific printing engine prints the printing bitmap to output a printed version of the graphic document with the secure patterned color in the security area. The security area of the printed version of the graphic document has a color appearance, and the secure color does not identify the type of security feature within the secure patterned color.
