Methods, systems and processor-readable media for dynamically detecting and switching profiling configurations

摘要

Methods and systems for dynamically detecting and switching profiling configuration in digital rendering. A set of color patches utilized for profiling can be rendered via a calibration engine and the color patches can be measured via inline/offline spectrophotometer. A high-accuracy MFD model can be built based on measurement from the color patches. A set of measurement values for a set of CMYK color probes can be obtained directly from the measurement and/or by processing through a MFD model. A classifier can be configured to determine a toner set based on the predicted and/or measured Lab values. The profiling procedure then automatically sets up a parameter set for the corresponding toner set to build a color look-up table via an inversion and optimization function. A destination ICC profile can be built based on the color LUTs. The system can handle multiple toner sets and produce optimized color outcome for each toner set.

1. A method for dynamically detecting and switching profiling configurations, said method comprising:
rendering a plurality of color patches via a multi-function device; measuring said plurality of color patches to obtain measurement values; generating a multi-function device model based on said measurement values; obtaining Lab values for said plurality of color patches from said measurement values; configuring a classifier to determine a toner set being utilized by said multi-function device based on said Lab values, generate a parameter set for said toner set, and build color look-up tables; building a destination International Color Consortium profile based on said color look-up tables; training said classifier offline by comparing a multi-function device gamut between at least two different toner sets; locating an area that yields a large difference between at least two gamuts; determining a plurality of CMYK color probes; and obtaining a toner property via said measurement of said plurality of CMYK color probes for said at least two different toner sets.
