Abstract
Printed matter has printed informational content. This refers to the content of a given document which is relevant to the intended reviewer, e.g., the printed text of the letter or pictures. According to the invention, the printed matter also, however, comprises a print control symbol. This symbol is located at a predetermined position on the printed matter, which is separated from the printed informational content. The print control symbol is hidden such that it is not apparent to a reviewer of the printed matter and encodes information concerning the printed matter such as sequencing information, which is relevant to the printing system during printing and mailing, for example.
