Tips of printing:
UV inks are detailed by usage
UV inks can be divided into two major categories, namely, UV printing inks and UV printed circuit board inks. At present, UV printing inks used in the printing industry cover various printing fields such as offset printing, embossing (including flexographic printing), gravure, screen printing and inkjet printing, while UV printed circuit board inks are mainly used in circuit boards in the electronics industry. (PCB) printing.
1. Offset UV ink
Offset printing uses UV ink, which can eliminate powder spraying, which is conducive to the cleaning of the printing environment, and avoids the troubles caused by the powder coating to the post-press processing, such as the effect of glazing and film coating, and can be connected. Processing.
UV inks also prevent ink crusts, which solves the worries of offset presses while increasing drying speed. Especially in packaging printing, it is often necessary to print a large area of the field, requiring a higher density, so the amount of ink has to be increased, and the drying problem of the ink becomes very important, and the printing is often affected by the difficulty of drying the ink. Productivity. With UV ink, this problem is solved.
UV inks are brightly colored and excellent in abrasion resistance, making them ideal for packaging and book cover printing.
UV inks are non-permeable when cured and can be printed on non-absorbent substrates, such as card printing, which is an area where ordinary offset inks cannot be used.
In addition, offset UV inks are also widely used in ticket printing such as direct mail and commercial forms. In foreign countries, the biggest market for UV inks is offset UV inks.
2. Letterpress printing UV ink
Topographic UV inks are mainly used for label printing as well as packaging printing, such as hose printing.
In flexographic printing, especially in narrow-width flexographic printing, people pay more attention to less downtime, stronger friction, better print quality, and the like. The products printed with UV ink have high dot density, small dot gain and bright ink color, which is a higher grade than water-based ink printing. UV inks have broad prospects for development.
Most flexographic presses today are equipped with UV curing devices and come in many varieties.
3. Gravure printing UV ink
In the field of gravure printing, UV inks have been selectively used, but the technology and cost have also been correspondingly improved. As the voice of environmental protection is getting higher and higher, and the requirements for the safety of packaging and printed matter, especially food packaging, are becoming more and more strict, UV ink will become a development trend of gravure printing ink.
4. Screen printing UV ink
The advantage of UV ink in screen printing is very obvious. Because it can only be cured under UV light, it will not cause a troublesome blocking problem on the screen, and the curing speed is fast, which solves the troubled silk well. The long-standing contradiction between the netting and the drying speed of the ink in the screen printing industry is that the ink layer of the screen printing product is thick and difficult to dry. If there is no drying device, the printed matter is difficult to accumulate and collect, and it is very difficult to realize high-speed printing. With UV ink, all this is solved. For example, in the printing of optical discs, all of the UV inks are used, which improves the production efficiency.
The use of some decorative UV ink printing in screen printing can produce some special effects to achieve the decoration of the printed surface. These special effects are difficult or impossible to achieve with other printing methods, only screen printing + UV ink can be achieved.
At present, the commonly used UV inks are of the following types: screen printing UV imitation metal etching ink, screen printing UV wrinkle ink, screen printing UV coral ink, screen printing UV ice ink, screen printing UV refractive ink, screen printing UV crystal grain ink Wait.
