Abstract

Claims (26)

1. A computer implemented color prediction method for color printing, comprising:

in response to loading media into a printer that does not include a preset for said media and initiation of a calibration sequence, using one or more sensors to measure physical properties of said media;

based at least upon said measured physical properties, identifying an optimal preset of model parameters in a database;

loading said optimal preset into said printer as said starting calibration;

determining a difference from values in said optimal preset loaded into said printer and those of said measured physical properties;

based upon said determined differences, fine tuning said optimal preset by:

instructing said printer to print a reference on said media;

using said one or more sensors to measure said reference printed on said media:

using said measurements of said reference to fine tune said optimal preset; and

saving said fine tuned preset as a new media profile.

2. The method of claim 1 , further comprising:

building a model for describing a color fingerprint of a desired setting based on one or more sensor measurements.

3. The method of claim 2 , further comprising:

creating said model parameters;

loading said parameters from a database to compute a simplified calibration and characterization process; and

loading said parameters from said database for any of comparison with, and measurement of, image data.

4. A computer implemented color prediction method for color printing, comprising:

with a processor, in response to loading media into a printer that does not include a preset for said media, initiating a calibration sequence using one or more sensors positioned on said printer to measure physical properties of said media;

said processor using said sensors for acquiring information regarding said media before ink is printed on said media and after ink is printed on said media;

said processor, based at least upon said measured physical properties, identifying an optimal preset of model parameters in a database within said printer;

said processor loading said optimal preset into said printer as a starting calibration;

said processor determining a difference from values in said optimal preset loaded into said printer and those of said measured physical properties;

said processor instructing said printer to print a reference on said media;

said processor using said one or more sensors to measure said reference printed on said media;

said processor using said measurements of said reference to fine tune said optimal preset; and

said processor saving said fine tuned preset as a new media profile in said database for said media.
