The key to choosing the correct coating and prepress solution in the six UV inkjet printers!

On a global scale, especially in China, UV inkjet printers, UV flatbed inkjet printers, flatbed inkjet printers, and platform inkjet printers have achieved double-digit speed growth over the past few years. UV printing speed, high quality and solvent-friendly. Among these advantages, the biggest highlight of UV lithography is its diversification of printed substrates. Previously unprintable glass, ceramics, metal, acrylic, wood, UV lithography can achieve high quality printing results. However, the UV ink quickly dries, and the glass, ceramic, metal and acrylic and some smooth wood surface, UV ink adhesion is not good, it is easy to fall off. Therefore, although many manufacturers promote "uncoated" UV printing, it is an essential process to use a flatbed printer coating to assist UV ink adhesion in market applications, especially in highly demanding industrial applications.

The right choice of UV inkjet printers, flat inkjet printers, flatbed inkjet printers, flatbed printer coating (preprinted liquids) can not only guarantee the quality of printed products, but also have a very important impact on the protection of expensive equipment. Because UV printers, UV flatbed printers, flatbed printers, and platform printers do not take long to appear, many users of UV flatbeds do not understand their performance. Now on the market UV inkjet printer - UV flatbed inkjet printer - flatbed inkjet printer - platform inkjet printer coating levels. If improperly selected, poor quality flatbed printer coatings can cause damage to the machine.

In selecting the coating of the UV flatbed printer, we must pay attention to the following six issues:

1. Adhesion: There are several ways to measure adhesion, such as 100-gram method. If the quality of the printed product is high, it is also possible to test whether the printed product is immersed in water or whether the painted surface is peeled off. Adhesion is the key to measuring UV inkjet printers and flat panel printers. High-quality UV inkjet printer / flatbed printer coating should pass Baige test, and do not fall off after soaking in water or boiling water.

2. Leveling: Leveling is a common performance indicator in a coating. It means that the paint has been painted or sprayed on the surface of the object. The brush marks and spray mist particles appear on the coating film are automatically flattened into a flat surface. Smooth surface capabilities. Poor leveling UV inkjet printers and flatbed inkjet printer coatings can affect the decorative effect of prints. More importantly, if the brush marks on the surface of the coating do not disappear, the uneven surface of the coating may rub against the nozzle of the UV printer, causing significant damage. High-quality UV inkjet printer, flat inkjet printer coating should be tightly packed and quickly leveled after brushing or spraying.

3, film transparency: As a high value-added decorative products, UV prints on the appearance of the requirements are generally high. This requires UV inkjet printer, flat panel printer coating film colorless, transparent. There are some two-component epoxy resin-based coatings on the market that are yellowing and affecting the decorative effect.

4, weather resistance: For UV printing products, especially in the outdoor use of signs, billboards, printed materials must be long-term bright as new, do not fade. Specifically, this requires a UV inkjet printer, the coating of the inkjet printer being UV-resistant. Some UV flatbed printers now coat yellow under long-term lighting conditions and are not suitable for outdoor use. Even UV printing products used indoors only need to consider the use of weather resistant UV inkjet printers and flatbed inkjet printers to ensure product quality.

5, the ease of use: the current market, UV inkjet printer, flat panel printer coating has a two-component or multi-component products, in the use of the required ratio according to the manufacturer prior to configuration, inconvenient. Compared to multi-component products, there is a greater advantage in the use of a single-component UV flatbed printer coating that does not require configuration.

6, product safety: product safety is also the choice of UV inkjet printer, flat panel printer coating must be considered. Solvent-based UV inkjet printers, flat inkjet printers coating not only odor, but also in the storage of security risks, transportation is not easy. Because of the high investment in UV flatbed printers, in the selection of UV inkjet printers, it is best to consider safer waterborne UV inkjet printers and flatbed inkjet printer coatings for flatbed inkjet printers. If it is necessary to use a solvent-based coating, it is advisable to store it separately from the UV printer and flat panel printer to prevent potential safety hazards.

U.S. Huajinsi's UV inkjet printer, flatbed printer coating (plating printer coating | prepress liquid) is an environmentally friendly waterborne coating developed with international advanced materials technology, excellent adhesion, soaking for 24 hours, Boil for 1 hour without falling off. On the basis of high adhesion, UV inkjet printer \ flat inkjet printer coating leveling is good, transparent film, excellent weather resistance, is an excellent choice for UV inkjet printer - flat jet printer, will promote UV printing to glass, ceramic tile , Metals, plastics and other diverse substrates development.

Bag In Box also called BIB, extensively used in packing liquid product like wine, juice, cocktail and drinks. It is usually made of several layers of laminated film, put in a paper box as finally packaging. Products can be stored in good condition for weeks as its high barrier property. This kind of flexible packaging reduces the packaging storage and packaging cost for large volumes, and also offers an environmentally friendly alternative to other types of packaging. Customers can reduce their environmental impact by reducing waste, using less energy, and conserving raw material. Lanker provides customized packaging solutions for clients from all over the world.
