Four-color printing is the color achieved by CMYK four basic printing color stacking nets. From the printing effect, the network cable is more obvious, the surface is relatively rough and not full enough; the spot color is prepared by the printing ink blending engineer according to the special color color card. Carry out the printing process. From the printing effect, the color of the spot color printing is more full and bright, and from the perspective of printing cost, the spot color printing is higher than the four color printing.
It is recommended to use spot colors in the case of large-area color printing, because large-area four-color printing will obviously cause color difference and color unevenness; we recommend using spot color printing when customers are sensitive to color or follow the sample color. It is easier to get close to the sample color by printing with spot colors.
