A system is disclosed comprising a color image producing device for providing a test pattern on a medium, said test pattern comprising a plurality of color patches, said test pattern having a principal orientation axis under a non-perpendicular angle &#x3b1; with the propagation direction of the medium through said color image producing device; and a color measurement device coupled to receive the medium from the color image producing device and arranged to propagate the medium in said propagation direction, the color measurement device being further arranged to measure the colors of the respective patches of the medium during said propagation, the color measurement device comprising a color sensor mounted on the carriage oriented substantially perpendicularly to the propagation direction. The present application further discloses a color image producing device and a color measurement device that can be used in such a system, and a method for measuring colors with such a system.

System, color image producing device, color measurement device and color measurement method

A method of forming a color selection including selected color points. A first cluster in a color space is provided, the cluster being associated to a first color representation system. A second cluster in the color space is provided, the cluster being associated to a second color representation system, whereby the second cluster differs from the first cluster. A predetermined color point in the color space is provided. Included in the color selection are at least a first selected color point and a second selected color point, the first selected color point being the point of the first cluster which among all points of the first cluster is closest to the predetermined color point and the second selected color point being the point of the second cluster which among all points of the of the second cluster is closest to the predetermined color point.
