| titleOfInvention | Metal sheet printing sheet identification method and apparatus |
| abstract | PROBLEM TO BE SOLVED: To provide a method and an apparatus for accurately detecting a color mark attached to a metal sheet printing sheet made of an iron sheet or the like. SOLUTION: In the metal sheet printing sheet identification method, the metal sheet printing sheet 7 is identified by detecting a color mark 8 attached to the metal sheet printing sheet 7. A spectral reflectometer (which has a light projection angle of 0) that receives reflected light in an oblique direction other than the vertical direction with respect to the sheet surface of the metal sheet printing sheet 7. The spectral reflectance from the metal plate printing sheet 7 is measured by a spectral reflectometer 13) having a degree of 45 ° and a light receiving angle of 45 °, and the chromaticity (CIE-L * a * b * coordinates) is measured based on the spectral reflectance. The chromaticity a * or b * ) is calculated, and the presence or absence of the color mark 8 is determined by comparing the chromaticity a * or b * obtained by the calculation with a predetermined chromaticity threshold value. . |
