  • Patent number: 8351075
    Abstract: A print mediator includes an interface module which serves as an interface for a document to be submitted for printing. The interface module communicates with an associated printing infrastructure for acquiring color rendering information for a print queue of the printing infrastructure. A reviewing application receives the acquired color rendering information and generates a visual representation of a document to be submitted for printing based thereon. Problems relating to color rendering by the printing infrastructure are detected and proposals for correction are presented to the submitter by the reviewing application. The user can review the proposals and accept or reject them as well as making annotations on the document. An analogous reviewing application is accessed by the print shop operator to review the document and submitter's annotations.
