A full-colour page is a page in a publication, such as a magazine or book, that is printed using a combination of four primary colours (cyan, magenta, yellow, and black) to create a wide range of vibrant hues and shades. This printing process, known as CMYK, allows for the reproduction of high-quality images and graphics with rich, lifelike colours. Full-colour pages are often used to enhance the visual appeal and impact of a publication, making it more engaging and eye-catching for the reader. They are also commonly used in advertising and marketing materials to showcase products and services in their full, vivid glory.
