Spot color printing is a printing method that breaks away from the conventional printing method and uses special inks other than yellow, magenta, cyan and black to perfectly restore the original color. In packaging and printing, it is often used to create a large area of unique background color, which makes people shine. This paper will discuss the advantages and applicable occasions of spot color printing to help readers better understand this printing method.

High saturation ink color

Ink for spot color printing is prepared according to the principle of pigment subtractive mixing, with low brightness and high saturation. This spot color block with uniform ink color is printed on the spot color, and the ink quantity increases, which reduces the sensitivity of ink layer thickness to color change and makes it easier to achieve uniform and thick printing effect.

An unparalleled advantage.

Generally speaking, spot color printing shows unparalleled advantages in specific occasions with its unique color reproduction and printing effect. Compared with four-color printing, it highlights its outstanding performance in color control and printing quality.

Applicable occasions

Spot color printing is suitable for packaging or book cover composed of uniform color blocks or regular gradient blocks with different colors and characters. After color separation, these color blocks and characters can be overprinted with four primary color inks or mixed with spot color inks. Only one spot color ink is printed on the same color block, which can improve the printing quality and save overprinting times. In addition, when printing a large area of light uniform color blocks, spot color printing is easier to get uniform and heavy color effects.
