4 Color Offset

Four-color offset printing, also known as CMYK printing, is a printing technique used to reproduce full-color images and text. It involves combining four ink colors: cyan (C), magenta (M), yellow (Y), and black (K), in varying proportions to create a wide spectrum of colors. These four colors are printed in layers of dots, which blend together when viewed at a distance to produce the desired colors and shades.

The process typically begins with separating the image into four color channels, one for each ink color. Then, each color channel is transferred to a printing plate. As the printing press runs, each plate applies its respective color of ink onto the printing surface (usually paper), one color at a time, in precise registration with the others. The overlapping of these colors creates the illusion of a full-color image.

Four-color offset printing is commonly used for a wide range of printed materials, including brochures, magazines, posters, and packaging, due to its ability to accurately reproduce vibrant colors and intricate details.
