| Abstract: | The principle of detecting overprinting deviation is analyzed and a method to avoid the overprinting detection error caused by the spectrum response of the photoelectrical detector is discussed. Based on this method, a precision color mark detecting device is designed, which can obtain the constant time delayed pulse of the centre of each color mark pulse. The delayed pulse is exactly correlative to the color mark and a high measurement precision can be reached with this designed device. |
| Keywords: | Color printing Overprint Color mark Spectrum response |
