Benefits of technology
The patent text describes a method for improving print quality by measuring and calibrating the colors printed on a media. The method aims to provide a smooth color transition and well-balanced contrast, lightness, and hue distribution. To achieve this, the method requires fewer printed patches and uses embedded measuring devices inside the printer to provide a process that is simple and fast. The technical effects of this method include improved print quality, faster and more efficient calibration process, and reduced cost of color printing.
Problems solved by technology
Such process is complex and concerns such factors as, for example, technical analysis for defining the best setting before running a complete calibration and / or characterization process, calibration, characterization, special effect creation, proofing, and quality control.
Such approaches are not flexible in a production setting.
Thus, it is not possible to calibrate a printer during production of the printer for a new media that becomes available after the printer is sold, nor is it possible during such manufacture to take into account such environmental factors as the influence of temperature variations on the final print.

Embodiment Construction
[0023]Embodiments of the invention address three fundamental concepts:[0024]Measuring the media and a small number of patches of ink to look up an optimal preset of model parameters in a database and then to modify model parameters based on the delta between the measured values and the preset (or more generally an interpolation between multiple presets if that makes more sense);[0025]A media and ink model that allows one to measure far fewer patches, especially for characterization, and a database of model parameters; and[0026]A process of calibration and / or linearization and characterization that iterates and goes between the two.
Simplifying Calibration and Characterization
[0027]FIGS. 1A and 1B show calibration and characterization (FIG. 1A) and simplification of calibration and characterization according to the invention (FIG. 1B).
[0028]Currently, there are two solutions for defining a calibration and / or a characterization (see FIG. 1A). In FIG. 1A, in the state of the art either ...

Color prediction for color printing is performed in response to loading media into a printer and initiation of a calibration sequence, using one or more sensors to measure physical properties of the media. Based at least upon the measured physical properties, an optimal preset is identified in a database and the optimal preset is loaded into the printer as a starting calibration. A difference from values in the optimal preset loaded into the printer and those of the measured physical properties is determined and the printer prints a chart. The sensors measure the chart and the measurements of the chart are used to fine tune the optimal preset. The fine tuned preset is then saved as a new media profile.
Description
BACKGROUND OF THE INVENTION[0001]1. Technical Field[0002]The invention relates to printing. More particularly, the invention relates to color prediction for color printing, as applied to technical analysis for defining the best setting before running a complete calibration and / or characterization process, calibration, characterization, special effect creation, proofing, and quality control[0003]2. Description of the Background Art[0004]In color printing, prints consist of images and the colors that make up the images. Such process is complex and concerns such factors as, for example, technical analysis for defining the best setting before running a complete calibration and / or characterization process, calibration, characterization, special effect creation, proofing, and quality control. In one example, it is necessary to provide an accurately calibrated printer if the print is to be a faithful reproduction of the original image. When performing a calibration before printer productio...
