Abstract: A system and method include a printing system with printing modules through which print media is transferred. The printing modules include sensors and a fault detection component. A printing system includes a fault identification system (FIS) and a scheduler. The FIS includes, a machine learning component, a Dependency-matrix component and an optimal search component. The optimal search component repeatedly implements a Rate of Return (ROR) that links the probabilities of occurrences of faults to a priori probabilities of faults and a detection function of the ROR to elements of the D-matrix, determines a ROR value, provides a benefit, and sends one more test to a scheduler of the printing system, which then physically implements the one more test. The prior steps are repeated until a stopping condition is reached and a fault is diagnosed.

Abstract: A methodology is disclosed to achieve adaptive illumination independent matching of spot colors. In one embodiment, the methodology includes an iterative process to determine a variety device specific recipes for spot colors across different illumination spectra, and then automatically choosing and/or recommending the optimal recipe that provides the lowest color dispersion across a variety of illuminants under consideration. This approach may be used with a variety of gamut mapping techniques. According to a further embodiment, the methodology may be used with a ray-based gamut mapping method.

Abstract: This disclosure relates generally to methods and systems for color management in image/text printing or display systems, and more particularly to a system and method for automatically achieving spot color production through use of a plurality of gain matrices per spot color in determining spot color coordinates. Furthermore, this disclosure provides a means for mapping out-of-gamut target spot colors substantially near a boundary of the gamut of an image output device, such as a printer or display.
