Four-Color Printing

Four-color printing is an offset printing method that reproduces full-color images using cyan, magenta, and yellow (the three primary colors) along with black, based on the subtractive color mixing principle. The visual lightness of four-color prints tends to follow a near-linear response, often resulting in an excess of neutral gray components in the final printed colors.

Spot Color Printing

Spot color printing refers to a process that uses inks other than the standard four (cyan, magenta, yellow, and black) to reproduce the original colors. Its key characteristics include:

·Accuracy – Each color has a fixed hue, ensuring consistent color reproduction.

·Solid Coverage – Spot colors define areas with solid, uniform color.

·Opacity – They provide strong coverage and can effectively mask underlying layers.

·Wide Color Gamut – The available spot color libraries offer a broad range of colors.

Screen Printing

Screen printing is a process in which a mesh—made of silk, synthetic fibers, or metal—is stretched over a frame, and a stencil is created using hand-cut lacquer film or photochemical plate-making methods. Its key characteristics include:
