Dot is the smallest in lithography printing.
All images are composed of tiny dots that cannot be discerned by the naked eye. The dots on the print must be seen through a dot pen or a magnifying glass.
Color, outline, and shade are expressed by the size and density of the dots. Because of the characteristics of dots, lithography is superior to other printing methods in halftone and colorful prints.
The four raw colors of printing are CMYK (cyan, magenta, yellow, and black). In lithographic plate making, the software will be used to analyze the four-color ratio of graphics and text, and the four colors will be made into four plates, one plate corresponding to one color ink tank. During printing, the four colors are superimposed on the paper by the printing press, and the original graphics and texts are reorganized.
In fact, the dot is angled
Because printing is to regroup the dots of the four colors back onto the paper, the dot angles of the four versions must be different so that the colors are evenly distributed on the paper, rather than stacking together to become black.
※The color will become darker when the color material is added, and the color will become brighter when the color light is added.
