A transparent white ink composition is formulated to brighten, lighten and or dilute full-tone primary inkjet colors: cyan; magenta; yellow and black, eliminating the need for ‘light ink’ primary color inks. The transparent white ink is jetted concurrently with reduced amounts of full-tone inks in lighter tonal areas conventionally supported by ‘light ink’ primary inks. Printing ‘light ink’ primary colors using a transparent white ink composition may reduce the number of print channels needed to print all four primary colors and the four ‘light ink’ primary colors. Embodiments of the transparent white ink composition may be solvent- or water-based, drying by evaporation of the carrier fluid. Other embodiments may be radiation-curable ink compositions. An inkjet printer includes print carriage and print head assemblies configured for jetting a primary color ink and the transparent white ink in the same pass in correct proportions to achieve a desired effect.

A nano-LED containing an array of nano-pillars of different diameters that are distributed over an emission area of an LED chip is capable of emitting broadband and white or nearly white light. Since each pillar emits light at a different wavelength according to its diameter and strain state, the overall emission spectral characteristics of the device is a combination of individual spectrum, giving rise to broadband emission. The spectral shape can be tailored for different shades of white emission, by controlling the distribution of the different diameter nano-pillars. The nano-pillars are patterned by nanosphere lithography.

A method of controlling tint of a tintable window to account for occupant comfort in a room of a building. The tintable window is between the interior and exterior of the building. The method predicts a tint level for the tintable window at a future time based on lighting received through the tintable window into the room at the future time and space type in the room. The method also provides instructions over a network to transition tint of the tintable window to the tint level.

An image display device includes a smoothing unit that filters the image data to be displayed. According to one aspect of the invention, only bright parts of the image that are adjacent to dark parts are smoothed, thereby improving the sharpness of dark dots and lines displayed on a bright background. According to another aspect, different primary colors are smoothed with different characteristics, enabling unwanted colored tinges to be removed from the edges of white areas. According to still another aspect, smoothing moves the luminance centroids of all primary colors in a direction in which the display screen is scanned, to reduce ringing effects without needless loss of edge sharpness.

The invention discloses a color migration method of color images. The color migration method is used to adjust the tone of a present color image by taking a specific color image as reference, and the tone of a processed output image is similar to that of the reference image. The color migration method comprises the steps of establishment an intermediate image, meshing and color migration. The method can be used to realize color migration between color images automatically and more effectively without manual intervention, especially a better color migration effect can be obtained under the condition that the tone of the image to be processed is greatly different from that of the reference image.

The present invention relates to color matching and repair delivery systems and more particularly to the delivery of a gradient variety of shades of color of a gel coat, resin, and or paint in its liquid form, for the matching and repairing of and to existing colored surface and body structures and in the repair to gel coat and fiberglass surfaces and bodies typically found in and on boats, aircraft, tubs, showers, dock boxes and the like. The general purpose of the present invention relates to a method and delivery system for color matching gel coat to gel coat and fiberglass surfaces. The present invention and system allows users to color match their fiberglass gel coat surface repair by using a kit that eliminates the need for messy mixing of multiple components needed to perform the typical fiberglass gel coat repair. The system dispenser includes multiple chambers or component reservoirs that hold and contain the fiberglass gel coat resin color solution. Chamber number one (the main chamber) contains the “base” color while the remaining chambers contain the tint and shade colors. The multiple chambers form a unit with the attached pumping head. The variable extraction ratio of the base coat color and the tint or shade colors are controlled in the pump action head as it draws or pushes out the specified and chosen color mixing ratio as matched to the accompanied color match card.

The present invention is directed to a process for predicting the tint strength of a pigmented coating composition, such as automotive OEM or refinish paint, on a real time basis while it is being made. The tint strength of a coating resulting from a layer, obtained by adding a reference binder to the coating composition, is measured. The process is repeated by subjecting the coating compositions to successive grinding intervals. The tint strength vs. reflectance is plotted on a graph and then by using a curve fitting equation, a tint strength prediction curve is obtained. By measuring the reflectance of a wet layer of a target coating composition, the tint strength of that target coating composition can then be predicted by using the tint strength prediction curve. The process is most useful during the manufacture of coating compositions, such as automotive OEM and refinishes paints.

A portable color corrected light for the correct matching of tooth shades and acceleration of tooth whitening has been developed. In order to accurately match the tint and hue (true color) of teeth, the device provides 5500 to 6500 Kelvin, ambient-independent light with the ability to block or overwhelm ambient light to get a precise “color” reading of that tooth. The same light can accelerate the tooth whitening process with the addition of photo-accelerators to increase the decomposition of H₂O₂ or other peroxide whitening material. In addition, the same light can also serve as a dental operatory light which provides a closer to daylight illumination than conventional halogen dental lights.
