目前,济南印刷对印刷品质量进行检测与控制的方法主要有:主观目测法、密度检测法、色度检测法和图像检测法:
At present, the methods of detecting and controlling the quality of printed matter in Ji'nan printing factory are subjective visual inspection, density inspection, chroma inspection and image inspection:

1、济南印刷主观目测法。工人采用手持式放大镜观察印品,与样张对比后,根据经验适当调节印刷水墨量以取得满意的印刷质量。该方法受人为及外界因素影响较大,不大可能得出统一的结论,不能全面反映印刷品的质量特性,但却是印品质量好坏的最后仲裁。

3 colorimetric detection method. Color measurement is directly from the side of the printed image measurement, color data, by calculating the proofs and standard test samples corresponding point on the color value, according to the color value to determine the size and standard test samples on the proofs are the same color, to determine the location of the color reproduction is correct.
