Abstract
Abstract A printing system for high fidelity printing of an image is provided comprising a print grid including a combination of the color black and five discrete basic ink colors, at least three colors having at least a portion of fluorescent. The printing system includes a spectrophotometer for measuring the color combination in the print grid. A plotter is used to plot readings from the spectrophotometer in CIE color space and creates a look up table based on the readings. A scanner then scans the image in RGB format and converts the scanned information into XYZ coordinates to be plotted in CIE color space. Thereafter, the scanner determines from the look up table the color combination for each scanned spot. In an exemplary embodiment, the five basic ink colors may be selected from a group of colors from the PANTONE MATCHING SYSTEM TM , while the fluorescent may be selected from a group consisting of PANTONE Fluorescents.
