Therefore, it is very important that how to select different processes according to the properties of spot color to realize the color consistency and accuracy of spot color printing. In this paper, different printing processes are used to print spot colors based on the solid and screening. Experiments are carried out to verify the feasibility and accuracy of different printing processes, which can provide a method for the printing of spot colors on product packaging.
