OEM Half-Tone Color Printing Everlight LED Membrane China Directly Factory

What is half-tone color printing?
Half-tone color printing is a printing technique that uses tiny dots of varying sizes to create the illusion of continuous-tone images, such as photographs, on a printed page. By varying the size and density of these dots, it can reproduce a wide range of colors and tones.

How does it work?
In half-tone printing, the original continuous-tone image is broken down into a pattern of tiny dots using a screen or raster. The size and spacing of these dots determines the perceived tone and color. Smaller dots appear lighter, while larger dots appear darker. By combining dots of different sizes and colors (typically cyan, magenta, yellow, and black), a full-color image can be reproduced.

Advantages of half-tone printing:

Cost-effective method for printing high-quality color images
Allows for high-resolution, detailed color reproduction
Can be used on a variety of printing presses and media
Widely adopted standard for commercial printing
