With the passage of time and the development of social and cultural undertakings, the forms of printing have become more advanced and diversified, and the uses have become more numerous. It can be made into gift boxes, books, publications, and so on. What I want to introduce today is the four-color printing that everyone often talks about in the printing industry. Four-color printing, as the name implies, uses CMYK (cyan, magenta, yellow, black) four-color overprinting of the colors you need. In layman's terms, it is to use the different superposition of these 4 colors to get the color you need. As long as the color has a gradient, it is printed in four colors. For example, the common gift boxes in our market are products overprinted with these four colors. The four-color printing is superimposed with dots, and you can see dots of different colors with a magnifying glass. If the printing process of using inks other than the four-color inks of yellow, magenta, cyan, and black to reproduce the colors of the original manuscript, it cannot be called 'four-color printing' but should be called 'spot color printing' or 'point color printing' '. The two are very different and should not be confused. So why are the four colors of cyan, magenta, yellow, and black, instead of three colors, or five colors, or more colors. Four-color printing means that colors are superimposed on different colors, yellow, cyan, and magenta. When printed together, different colors can be obtained. Red and yellow are mixed to form red, cyan and yellow are mixed to form green, and cyan and magenta are mixed to form blue. These three colors are continuously superimposed to obtain different colors but cannot be obtained. Black, so black will be added separately later, so that the result is bright and bright, and the printing effect is more significant. The above mentioned the characteristics of four-color printing, so what are its shortcomings? Color blocks printed with four-color printing, because the colors that make up the color blocks are composed of dots, the dots will directly affect the intensity of the color, which will cause uneven ink color, which is unstable, and because there are dots Existence, the ink color cannot be printed thickly on the product, and it will produce unavoidable patterns. In our lives, many products are produced by the four-color printing process, for example: exquisite color and colorful gift boxes, photos taken by color photography that reflect the colorful changes in nature, color art by painters work. It can also be used for packaging and printing of electronic products and food and cosmetics, such as data cable packaging boxes and cosmetic packaging boxes. These products have high requirements for color and craftsmanship. For economic reasons, they must go through an electronic color separation machine or It is a color desktop system for scanning and color separation, so four-color printing is the best choice. The content of the four-color printing process is introduced here. If you want to know more, please contact our company. Thank you for your reading and attention!
