What does the improvement of printing precision of UV printers depend on?

Many friends who are ready to buy UV printers cannot do without brand, price, after-sales service, machine quality, printing speed, and precision. Among them, speed and precision are the direct printing effects of UV printers. Of course, for industrial applications, the production quality of the machine itself, that is, stability is also very important.

Numerous UV printer manufacturers are also working tirelessly on how to further improve the precision of inkjet printing. UV inkjet printing is based on the subtractive method of cyan (C) magenta (M) and yellow (Y) three primary colors appear in colors. CMY these three inks can mix more colors, and the color gamut is wide. The three primary colors cannot be mixed to produce real black, and a special black (K) is required, so the four colors that UV printers often say are also CMYK.

The UV printer controls the inkjet action of the nozzles of different colors so that the ink of each color forms a dot on the printing medium. This imaging principle is called a semi-color impression, which means that only a single kind of ink appears. Color, and use different ink dot sizes, distribution density, and other methods to form a full-color picture.

The ink dot size has a prerequisite effect on the precision of UV printers. From the perspective of the development trend of inkjet print heads, the size of the nozzle holes is constantly getting smaller, the number of picoliters of ink drops is constantly decreasing, and the resolution is constantly improving. Nowadays, mainstream nozzles such as Kyocera, Ricoh, and Epson on the market have ink drops of several picoliters.

In addition, the addition of light-colored inks of the same color makes it possible to use more light inks instead of thick inks when low-density output is required, making the color gradation transition of the picture more natural, and the colors more full and layered. Therefore, friends who require high precision in UV printers can consider matching light cyan (Lc) and light magenta (Lm) inks, which are also six colors we often say, and can even be matched with third-order black ink.
