This invention relates to a non-contact coating method for producing a substantially continuous coating and articles constructed therefrom. The evaluation device comprises: a substrate; and a pattern imposed on the substrate. Each of the plurality of pixels is provided with a capacitance having two electrodes in which one is connected to a first electrode of a corresponding one of the plurality of pixels and another is supplied with a pixel-potential control signal by a pixel-potential control circuit. The cores having an outside diameter of 50 mm-1200 mm, a tapered angle of 10\xb0-45\xb0, and a slot depth of 10 mm-210 mm are advantageous.
