Rendering and outputting non-standard colorant

摘要

A system for rendering and outputting a non-standard colorant comprises a print driver for accepting identification of a document for output via a print operation, accepting identification of overlay data for use in the print operation, converting the overlay data into grayscale data, and generating a page description language document including data from the document divided into standard colorspace channels and an overlay colorspace channel, the overlay channels made up of the grayscale data and identified by a colorspace keyword; and a multifunction peripheral device for rendering the standard channels in standard buffers as directed by the page description language document, identifying the overlay channels using the color name keyword within the page description language document, rendering the overlay channel in an overlay buffer, and completing the print operation by outputting the contents of the standard buffers using standard colorants and the overlay buffer using an overlay colorant.

1. A system, comprising a multifunction peripheral device including:
a multifunction peripheral network interface for receiving a page description language document for output; a printer engine for: rendering standard colorspace channels in standard buffers as directed by the page description language document; identifying an overlay colorspace channel by identifying a pre-determined color name keyword associated with a specific overlay colorant in the overlay colorspace channel in the page description language document; rendering the overlay colorspace channel in an overlay buffer; printer hardware for completing a print operation by outputting the contents of the standard buffers using standard colorants and the overlay buffer using the overlay colorant.
