<p><P>PROBLEM TO BE SOLVED: To not only expose colors of prescribed layers merely by irradiation with lasers but make marking of full colors possible by decreasing the number of layers and the kinds of colors in subjecting a color marking plate having a plurality of the color layers to laser marking. <P>SOLUTION: The color layers of the color marking plate are formed of colors of Y, M and C color bases and color mixing of two colors is realized by exposing the neighborhood of the boundary of the two colors. The color visible as another color when superposed with a thin layer complies with the rule of a method for subtractive mixture of colors. The color marking plate of the five colors and seven layers are proposed here and the processing method by a laser marker is disclosed. Another one is to realize color mixing of the two colors by forming the color, layers of the color marking plate of the colors of the R, G and B bases and arranging spots provided with a slight color in proximity thereto. This color mixing complies with the rule of the method for additive mixture of colors as well. The color marking plate of the five colors and six layers are proposed here and the processing method by the laser marker is disclosed. <P>COPYRIGHT: (C)2003,JPO</p> |
