The inspection of chromatic aberration is mainly through checking with the standard sealing sample, and the color difference should be consistent at one arm distance. In terms of color, a 50x magnifying glass will be used to carefully check the color of the printed matter in the packaging. Generally, the color is combined by the dots one by one. If the color is wrong, the dots will appear irregularly distributed. Generally, the dots of packaging printing are regular, and the dots are circular. The inspection of the overprint error is mainly visual inspection to observe whether there is a phenomenon of printing ghosting. Peel strength and heat seal strength are mainly tested by AGS-5KNG electronic universal testing machine. The detection principle is the same as that of the computer tension meter. 8.
