20090314660 | Novel Electropolymerisable Monomers, Soluble in an Aqueous Solution and Comprising a Metalloporphyrin - The invention relates to novel electropolymerisable monomers which are to be polymerised in an aqueous solution and comprise: an electropolymerisable pattern selected from acetylene, pyrrols, thiophenes, indols, anilines, azines, p-phenylene vinylenes, p-phenylenes, pyrenes, furanes, selenophenes, pyrridazines, carbazoles, acrylates, methacrylates and the derivatives thereof, and a metalloporphyrine which is substituted by at least two ionised or ionisable entities in an aqueous solution. The invention also relates to a method for the polymerisation of such monomers, to the electroactive probe that can be obtained by the polymerisation of such monomers, and to a method for detecting a target ligand in a biological sample using one such electroactive probe. | 12-24-2009 |

20090009787 | MULTICOLORANT SEPARATION SYSTEM AND METHOD - A method separates a color vector into a colorant vector for a printing system that uses more than four colorants, for example cyan, magenta, yellow, black, orange and green colorants. According to the method, the separation process is split up into partial four colorant processes that contain opponent colors. For example, a first partial process is a cyan, magenta, yellow and black process; a second one is an orange, magenta, yellow and black process; and a third one is a cyan, green, yellow and black process. Continuity of magnitudes of the colorants is achieved across the boundaries of the color gamuts of the partial processes by imposing specific constraints on the combinations of colorants to render a given color. A computer implemented system and a print system are based on the method. | 01-08-2009 |
20090086223 | Method for creating a color link - The invention deals with a method for replacing the colorant values of a raster image by a new set of colorant values that is for example optimized for a standardized printing process. According to the invention, a forward look up table is identified that transforms the colorant values in the raster image into color values. The color values in this look up table are separated into new colorant values to obtain a colorant to colorant interpolation look up table. This is done by using an inverse transformation that is based on the forward look up table using appropriate separation parameters for the standardized printing process. The method has the advantage that it enables to map pure colorant values in the original image back onto pure colorant values in the transformed image. | 04-02-2009 |
20090190180 | METHOD AND APPARATUS FOR PRINTER CHARACTERIZATION - A one dimensional transformation of colorant values before transforming them into a color using a printer model enables linearization of the gradation of each color component as a function of colorant values. The method reduces interpolation error if the printer model uses piecewise linear interpolation. | 07-30-2009 |
20110310415 | METHOD AND APPARATUS FOR CALCULATING METAMERIC COLORS - A method for creating a set of metameric printed color patches on a color printer enables visual assessment under a specific illuminant if the colors of a printed product have faded. | 12-22-2011 |

20160112603 | SYSTEM AND METHOD FOR REGULARIZING AN INK MODEL FOR A COLOR DEVICE - A method including the steps of selecting an n-ink model for a color device, for transferring a set of colorant values in colorant space to a set of color values in color space; selecting a printer characteristic of the n-ink model, wherein the printer characteristic indicates the regularity of the n-ink model; evaluating, for the n-ink model, a set of one or more values and/or ranges for the printer characteristic, thus determining the regularity of the n-ink model; and modifying the n-ink model such that the modified n-ink model is regular, if, based on the evaluation, the n-ink model was not regular. | 04-21-2016 |

20120041872 | SYSTEM AND METHOD FOR PAYMENT DATA PROCESSING - A system for processing transaction data and payment data is provided. The system includes a front-end system that receives transaction data from one or more merchants, such as an employee identifier. A back-end system receives payment data from one or more payment systems, such as fraud data. A reporting system that is connected to the front-end system and the back-end system correlates the transaction data the payment data, such as to show employee identifier data and fraud data in a single record. | 02-16-2012 |
