Abstract
A document specification is examined to determine if it matches the device color characterization of a rendering device such as a printer. If it matches, then the document can be faithfully rendered by the device. Otherwise, the document specification must be transformed before rendering. A match can be detected by discovering a appropriate metadata within the document specification or within the document color characterization. Alternatively, a device signature can be used instead of a metadata.
