Abstract: A method and system for mapping color gamuts based on one-one and onto mapping function in order to create an invertible transform is disclosed. A hue leaf associated with at least two arbitrary color gamuts can be defined utilizing a vector math function and a most saturated point with respect to each hue leaves can be determined. A safe area relative to an intersection point can be estimated by approximating the most saturated point in both hue leaves. An upper hull and a lower hull associated with the hue leaves can be continuously sub-divided with an equal number of sections by constructing one or more vectors. An appropriate section for computing a vector relationship in the color gamut can be determined in order to map the color gamuts based on the continuous, one-one and onto function thereby creating an invertible transformation.

Abstract: A computer system and method for processing an enhanced business card is provided, wherein the enhanced business card has a value stored thereon. The computer system includes a memory device for storing data and a computer system associated with a service provider (SP) that includes a processor. The SP computer system is configured to communicate with the memory device and is programmed to receive identifying data identifying a recipient of the enhanced business card, provide the identifying data, including identifying data for the recipient, to an issuer of the enhanced business card, and load a value provided by the SP on the enhanced business card. The SP computer system may load additional value provided by the SP when the recipient of the enhanced business card performs an action predetermined by the SP.

Abstract: A method and system for improving visual calibration of a printing device is disclosed. A Pan-Dimensional Mechanism can be utilized for calibrating the printing device so that a gamma curve can be created once for each halftone. A grey calibration and a color calibration can be implemented under different light sources utilizing a comb pattern and a snowflake pattern for displaying color display parameters. A delta in value can be determined between composite greys associated with different light sources which can be added to an internal calibration value associated with a particular light source for color calibration. Such an approach can be implemented utilizing a touch screen front panel with various display methods for user interactions in order to set the color display parameters.
