Advantages of four color printing:
Non spot color printing is more affordable
For those customers whose color requirements are not very high, using non spot color printing is more affordable, because non professional people can not see the color difference between spot color printing and non spot color printing, at least in terms of sense.
Disadvantages of four color printing:
There is a certain deviation in the color of non special printing
Because the color of non spot color printing is adjusted by CMYK color value, which is more or less different from the original manuscript color, but non-specific printing is more suitable for public customers. The visual lightness of four-color printing color is close to straight line, which shows that there are too many neutral gray components in printing color. Four color printing emphasizes on enhancing the saturation of copied colors at the expense of color brightness, which is another important defect of four-color printing technology.
Compared with the color of natural scenery, due to the above defects, the color reproduction of four-color printing is heavy, the gradient distortion is large, the sense of hierarchy is not real, and the three-dimensional sense is not strong. Therefore, customers often complain that the printing quality is not high.
