Abstract: A method is provided for testing a diffusely reflective liquid for colour strength, said liquid comprising particles in a carrier medium, e.g. white emulsion paint based on titanium dioxide. The method comprises measuring in situ a lightness parameter of the liquid, of the carrier medium and of the liquid diluted with amounts of carrier medium; and determining from said measurements a dilution parameter indicating the amount of carrier medium needed to produce a predetermined reduction in the lightness parameter of the liquid, said dilution parameter providing an indication of colour strength. The lightness parameter may be L* in the CIE L*, a*, b* colour space, and the test may be carried out using a diffuse reflection probe (10) configured to direct light from said probe (10) into the liquid and configured to collect a portion of the light from the probe (10) diffusely reflected by the paint for determining the lightness parameter. The results may be used for process control e.g. in emulsion paint manufacture.

Abstract: In a color imaging system, multiple rendering devices are provided at different nodes along a network. Each rendering device has a color measurement instrument for calibrating the color presented by the rendering device. A rendering device may be a printer in which the measuring of color samples on a sheet rendered by the printer is provided by a sensor coupled to a transport mechanism which moves the sensor and sheet relative to each other, where the sensor provides light from the samples to a spectrograph. A rendering device may also be a display having a member supporting a color measuring instrument for receiving light from an area of the screen. The color measuring instruments provide for non-contact measurements of color samples rendered on a display or a sheet, and are self-calibrating by the use of calibration references.

Abstract: LED based illumination modules are realized that are visually color matched to light sources not based on LEDs based on visually matched color spaces. A visually matched color space is employed to both instrumentally and visually match an LED based light source with a light source not based on LEDs. In one aspect, an LED based illumination module is realized to achieve a target color point in a visually matched color space within a predetermined tolerance. In another aspect, an LED based illumination module is realized to visually match a light source not based on LEDs. A target color point in the CIE 1931 XYZ color space is derived based at least in part on the spectrum of the visually matched LED based illumination module. LED based illumination modules visually matched to light sources not based on LEDs are realized based on the derived target color point.

Abstract: One embodiment of a method for calibrating a test color measurement device in conjunction with an emissive display includes measuring spectral sensitivities of at least four channels of a more-than-three-channel sensor in the test color measurement device, linearly regressing the spectral sensitivities to a least-square best fit to Commission International de l'Éclairage (CIE) color matching functions, wherein the linearly regressing is performed using a weighting function that is based on a square root of a spectral power distribution characteristic of the emissive display or of a type of the emissive display, and computing a set of initial fitting coefficient values from the linearly regressing.

Abstract: A method and system for accurate and precise representation of color for still and moving images, particularly sequences of digitized color images. Spectral and/or extended dynamic range information is retained as images are captured, processed, and presented during color adjustment. Using this extra spectral information, various methodologies for further presenting or processing the color within these images can be optimized. Presentation-device independence is achieved not by attempting to discover a device-independent intermediate representation, but rather by deferring the binding and mapping of color representation onto a presentation device until its actual use.
