Abstract
A system and methods for providing user-generated color tonal reproduction curves (CTRCs) to enhance color information when the prints will be made on a monochrome or highlight color printer. A graphical user interface (GUI) is provided to allow the user to generate tonal reproduction curves (TRCs) for each of the four separations of the color images thereby choosing what color features for the given document need emphasis on the monochrome printers. The same TRC may be applied to the color objects in a page description language (PDL) file.
Claims20
A method for enhancing color information, comprising:
- providing an interface for creating and maintaining at least one user-generated color tonal reproduction curve (CTRC);
- storing the user-generated CTRC,
- applying the user-generated CTRC to a page description language (PDL) file;
- and
- sending the PDL file to a non-color printer.
A system for enhancing color information, comprising:
- an graphical user interface (GUI) for creating and maintaining at least one user-generated color tonal reproduction curve (CTRC);
- a memory for storing the user-generated CTRC;
- a processor for applying the user-generated CTRC to a page description language (PDL) file;
- and
- a communications component for sending the PDL file to a non-color printer;
- wherein the processor is connected to the memory and communications component;
- and
- further wherein the memory stores instructions for the interface.
A computer-readable medium storing instructions for performing a method for enhancing color information, the method comprising:
- providing an interface for creating and maintaining at least one user-generated color tonal reproduction curve (CTRC);
- storing the user-generated CTRC;
- applying the user-generated CTRC to a page description language (PDL) file;
- and
- sending the PDL file to a non-color printer.
