Appl. No.:

09/775454

Inventors:

Michael J. Piatt - Dayton OH, US
Terry Wozniak - Springfield OH, US
Joseph Mangan - Granger IN, US

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G06K009/00

US Classification:

382167, 382165, 345590, 358518, 358520, 358525

Abstract:

A system and method are proposed for the printing of all possible colors, including all permutations of primary inks used to make processed colors, in equal increments and of a size easily measurable with a device that will convert the colors into standard color coordinates. These colors are categorized and used to determine the ability of the output device to reproduce a source color. Each color printed within the gamut of an output device is identified and correlated to independent color coordinates. The primary color recipe necessary to reproduce a reference color within the gamut of the output device is identified. The magnitude of deviation of out of gamut source colors is determined, and the closest in gamut colors are specified through methods of interpolation and nearest neighbor. Furthermore, the alteration in gamut size can be predicted based upon image manipulation processes associated with the workflow. Source colors can be correlated to the altered destination gamut in order to determine the recipe of in gamut colors.

International Classification:

US Classification:

358 19, 358520, 382165

Abstract:

The present invention addresses the quantification of a printed tone scale for each individual color in a printing system, developing a linear tone scale derived in an independent color space and referenced from the shade of the unprinted substrate. The present invention determines the threshold for excessive ink coverage of a printing system on a specified substrate. This determination is based on a subjective evaluation of acceptable thresholds for bleed, cockle, show through, and image density. The method works in conjunction with a predefined test pattern printed on the specified substrate at fixed printing parameters, such as speed, dryer temperature, and web tension. This invention also includes an ability to limit the ink of each independent color in the system as a fraction of the total upper ink limit. Furthermore, this invention allows calibration of the tone scale of each color in the system using the color of the paper as a reference point. In addition, this invention facilitates the generation of separate sets of tone scale transformations for both graphics and text for each color in the system.

Assignee:

International Classification:

H04N 1/40

US Classification:

358 31, 358 309

Abstract:

A system and method are provided for linearizing the tone scale of individual colors in a multi-color printing system, by deriving a prescribed tone scale of individual colors in a single or multi-color printing system. Full linear ink gradations are printed on multiple substrates, and a linearization table is generated with multiple points for each of the multiple substrates and/or ink gradations. A polynomial curve is fitted to the points of each linearization table to generate polynomial curves. At least one point in the polynomial curves is selected, that shows high variation from one curve to a next curve, and coefficients of a group of polynomial curves are plotted as functions of the value of the at least one point. The range of prediction can be as narrow or as broad as an application requires. Finally, a prescribed tone scale table is derived from the polynomial curves and the at least one point.

International Classification:

US Classification:

356402, 356446, 356328, 358 113, 358 19, 358500, 358504, 358402, 358446, 358501, 358 16, 702 81, 347 3

Abstract:

The present invention provides for the creation and use of a non-linearized, paper specific, digital workflow independent color profile which can be used to create proofs based on the raw output data of the source process. Such a profile would have the advantage of not having to have account for the intermediate workflow steps such as linearization, color correction, sharpening, ink limiting, color separation, dithering or color transformation because the gamut mapping would utilize the discrete output tones of the resulting data sent to the source device.

Abstract:

The present invention addresses the reformatting of a digital “ready to print” data file into a continuous tone (32 or 24 bit) file whereby discrete values in the tone range are uniquely assigned to specific binary combinations. The purpose for this transform is to facilitate further manipulation of preprocessed data. One application of the present invention is to exist as a critical piece of proofing workflow for a technology that reduces continuous tone data into a binary form representing droplet selection prior to output.

Abstract:

A system and method are provided for determining ink jet printing system parameters by selecting an appropriate linearizing transformation for application to images to be printed on a printing system for a specific substrate. These transformations can be any transformation capable of being applied in graduated increments and having a corresponding incremental visual influence on the printed output. The present invention allows the user to determine multiple parameters for the printer, including for example, tone scale correction, determination of upper ink limits, amount of under color removal, and allows the user to identify the proper ink level for optimum quality of graphics and/or text printing.
