  • Patent number: 6959111
    Abstract: A computer color-matching apparatus includes a colorimeter, a micro-brilliance-feeling measuring device, and a computer in which a plurality of paint blends, color data and micro-brilliance-feeling data corresponding to each of the paint blends, and the color characteristic data and micro-brilliance-feeling characteristic of a plurality of full-color paints are entered. A computer color-matching method for brilliant paints includes measuring the paint film of a reference color by a colorimeter to obtain the color data of the reference color, measuring the paint film of a reference color by a micro-brilliance-feeling measuring device to obtain micro-brilliance-feeling data of the reference color, and comparing the color data and micro-brilliance-feeling data of the reference color with the color data and micro-brilliance-feeling data corresponding to the paint blend previously entered in a computer, and selecting a prospective paint blend.

  • Publication number: 20020152132
    Abstract: Toning operations can be separated from a painting site by giving an order for toning operations to a toning person through a network. An orderer prepares a toning job including the calorimetric data nearby a repair portion, the type and a necessary quantity of paint, and the date of delivery and transmits the job to a selected toning person (1). The toning person checks an allowable limit of toning based on a designated paint, then prepares a toned paint (3) and sends the toned paint to the orderer by a home delivery service of packages or the like (5) A painter performs test painting with a supplied paint (6). When the test painting is OK, the painter actually performs painting with the paint. It is also allowed for an agent to select a toning person on-line. Moreover, it is allowed for the agent to select a toning person through tender on-line.
