METHOD FOR OPTIMIZING AN IMAGE PROCESSING AND PRINTING PROCESS

The invention relates to a method for optimizing colored images emitted by a color printer on the non-white surfaces of substrates and for optimizing the amounts of printing ink used, wherein an image motif is processed by means of a computer-assisted image processing system in order to form a master copy which is ready for output. The inventive method determines, for each pixel, whether and with what color density, a white underprint can be applied to a corresponding pixel, using an algorithm based on overall color density SF . The surface of the substrate is thus only underprinted with white on the pixels of the master copy where the overall color density is lacking or low. .

A spot color pattern system provides a naming convention that allows the user to name a custom spot color pattern. A Raster Image Processing (RIP) has a database of spot color patterns that are user definable and are patterns which are images of a textile, fabric, metal, etc., that are repeatedly printed across the job. The RIP interprets a spot color pattern name in print job, looks up the spot color in its database, pulls up the image associated with the spot color pattern name, adds Postscript(R) pattern code to the print job to paint the spot color across the background of the print job, realistically simulating the final print media, and adds other code to perform other tasks, such as mirroring or four-way mirroring to prevent stitches from appearing. A RIP user interface gives the user the ability to create, modify, or delete spot color patterns. The invention also provides a mechanism that allows an application program to access a custom spot color pattern from the RIP.

Method and system for color matching between digital display devices

A method and system for matching color displayed by source and destination display devices and particularly for providing color matching between a computer monitor and an ink printer. The technique of the present invention initially determines the combination and color value ratios of single destination color components that will cause the destination device to display a color that essentially matches each of fully saturated single and dual colors of a source display device. These combinations of single destination color components and their corresponding color value ratios determine the best available blends of destination device color components for printing source device colors. A color matching algorithm is employed to derive the color value ratios--one for each of the single destination color components.

Printing control device and printing control program

The information expressed by an original color image can be visually recognized even if the recording medium on which the color image has been recorded in dye ink is wetted with water. With a printing device equipped with pigment ink and dye ink, in the printing of a color image, the pigment ink corresponding to an image characteristic amount included in the color image is also injected along with the dye ink, so an image expressing the image characteristic amount included in the color image is recorded with the pigment ink, which has excellent water resistance, over the color image printed with the dye ink on the printing medium. Accordingly, in the event that the recording medium becomes wet and the dye ink bleed, the user can still make out the content of the information expressed by the original color image from the image printed in the pigment ink.
