Analysis of Influence of Proofing Method on Printing Color

What impact does the laboratory proofing method have on the color of the printed matter? Aiming at this problem, this article conducts detailed analysis and discussion through some experimental research and graphic description. From the experimental research to analyze the surface, even if the same batch of ink is used, the color difference will be affected by the proofing method, the substrate and the operator. Therefore, in reality The best way to do this is to determine the color tolerance of the ink used for proofing with reference to the normal variation level. The color difference range of the Prufbau magenta sample made by No. 6 laboratory using paper B is 0.9, and that of No. 3 laboratory is 1.0, which is smaller than the color difference range of the paper A color sample (see Figure 7). For the extreme value of each color sample (see attached table 2), take the maximum color difference between laboratories, magenta is 1.3, and cyan is 0.8. Choose the color sample with the smallest change, the color difference of the magenta sample is 0.10, and the color difference of the cyan sample is 0.03.
