Five reasons why the UV printing process makes companies unable to refuse
UV printing is to print a layer of oil on the pattern you want to print, mainly to increase the brightness of the product, protect the surface of the product, its hardness is high, it is resistant to corrosion and friction, and scratches are not easy to appear. UV printing is a printing process that uses UV light to dry and cure inks. It requires inks containing photosensitizers and UV curing lamps to complete the transfer of inks. UV inks have been used in offset printing, screen printing, inkjet, Printing and other fields.
The UV process generally referred to in the traditional printing industry is the print effect process, which is to apply a layer of varnish (with light, matte, inlaid crystal, glitter, etc.) on a pattern you want, mainly to increase the product Brightness and artistic effects protect the surface of the product.
So, what are the benefits of using UV technology for corporate packaging products? Next, let's talk about the five reasons why UV technology can't be rejected by enterprises.
1. Improve product performance
UV printing has good printability for most substrates. The dots of UV printing are clear, the tone reproduction is good, the ink color is bright and bright, and the printing consistency is high. At the same time, because the UV curing process is a photochemical reaction process, both the ink layer and the varnish layer have the advantages of strong adhesion, durability, water resistance, chemical corrosion resistance, wear resistance, and aging resistance.
2. Improve production efficiency and economic benefits
Drying by light curing, no heat source, no solvent, curing time is very short, the general UV process can achieve a line speed of 400 meters / minute, greatly improving production efficiency. After UV ink printing, UV glazing and continuous machining are performed to obtain a printed product with high gloss and uniform surface. After the machine is polished, the packaging and processing technologies such as die cutting, creasing, gluing and bronzing can be completed immediately, which is very conducive to the needs of high-speed printing development. High speed means that the storage costs and capital pressure of raw materials and finished products can be reduced. At the same time, due to the low energy consumption of UV curing, the usual operating costs are also greatly reduced.
3. Meet the environmental protection requirements
The entire curing system of UV printing is a solvent-free system, that is, a 100% solvent-free formula, which does not contain VOC, precisely adapts to today's environmental requirements. This is another important feature of UV-curable inks. Because the solid content of UV inks is close to 100% after curing, it is almost free of VOC (organic volatiles), that is, volatile organic compounds will not or rarely emit during curing. It will not cause more harmful environmental pollution, and it wastes less, saves energy, and does not have to worry about handling harmful combustible and explosive materials. It is an environmentally friendly ink.
4. Strong adhesion
The chemical substances in the UV ink form a polymer three-dimensional network polymer through the cross-linking reaction, so the use of UV ink can make the printed ink layer strong, quick-drying and cross-linking. Such an ink layer has high abrasion resistance And chemical resistance. Many prints printed on coated paper by UV ink for direct mail can withstand multiple folds and can withstand the strong radiation during laser printing again, so UV ink can be used for outer packaging printing that requires wear resistance.
5. Fast curing
UV ink will only dry under the irradiation of ultraviolet light, even if the ink is stored in the ink fountain for a long time, its performance can be kept stable, and there will be no skinning phenomenon on the ink roller. Once irradiated with ultraviolet light, the ink can be dried instantly, generally only 1 / 10S can be completely dried and fixed on the surface of the substrate. Traditional thermosetting inks and sheet-fed offset printing inks may take several minutes or even days to dry completely. Therefore, UV curing inks can be used to print live parts with short delivery time, which is comparable to flexo and gravure printing. Improve the production efficiency of printing.
In addition, the modern uv printing technology makes the nozzle not directly contact with the printing material, making the printer suitable for more materials. The new generation of uv flatbed printers developed based on this has been widely praised since it was put on the market, covering more than ten industries.
