How to correctly choose coating and pre-printing liquid in UV printing?

The correct choice of UV inkjet printers, UV flatbed inkjet printers, flatbed inkjet printers, and platform inkjet printer coatings (flatbed printer coating|pre-press treatment fluid) can not only ensure the quality of printed products, but also have a very important impact on the protection of expensive equipment. Because UV inkjet printers, UV flat inkjet printers, flat inkjet printers, flatbed inkjet printers, and platform inkjet printers have not been coated for a long time, many users of UV flatbed printers do not understand its performance. The coating levels of UV inkjet printers, UV flat inkjet printers, flat inkjet printers, and platform inkjet printers on the market are uneven. If you choose improperly, inferior flatbed inkjet printer coating will cause damage to the machine.


When choosing the coating of UV flatbed inkjet printer, we must pay attention to the following six problems:

1. Adhesion: There are many methods to measure adhesion, such as the hundred grid method. If the quality requirements of the printed product are high, you can also test whether the printed product has fallen off after being immersed in water or boiled and sprayed. Adhesion is the key to measure the coating of UV inkjet printers and flat inkjet printers. The coating of high-quality UV inkjet printers/flatbed inkjet printers should pass the 100 grid test and will not fall off after being soaked or boiled in water.

2. Leveling: Leveling is a common performance index in coatings, which refers to the automatic flow of brush marks and spray mist particles that appear on the surface of the object after the coating is brushed or sprayed. The ability to smooth the surface. The coating of UV inkjet printers and flatbed inkjet printers with poor leveling will affect the decorative effect of the printed matter. More importantly, if the brush marks on the coating surface will not disappear automatically, the uneven coating surface may rub the nozzle of the UV inkjet printer | flat inkjet printer, causing significant losses. The coating of high-quality UV inkjet printers and flatbed inkjet printers should be formulated with strict formulation and level off quickly after brushing or spraying.

3. Film-forming transparency: As a decorative product with high added value, UV printed matter generally has high requirements for appearance. This requires UV inkjet printers and flatbed inkjet printers to form a colorless and transparent film. At present, there are some two-component coatings based on epoxy resin on the market that form yellowish film, which affects the decorative effect.

4. Weather resistance: For UV printing products, especially signs, billboards, and printed materials used outdoors must be bright as new for a long time without fading. Specifically, this requires UV inkjet printers, flatbed inkjet printers, the coating has the function of resisting ultraviolet rays. Now some UV flatbed inkjet printer coatings will turn yellow under long-term light conditions, which is not suitable for outdoor use. Even for UV printing products that are only used indoors, it is generally necessary to consider the use of weather-resistant UV inkjet printers and flatbed inkjet printers to ensure product quality.


1.How long does the print-head working life?
A print-head can be used 2 years in regular working conditions.
2.What about the After-sales service ?
1. Provide customers with a systematic site layout proposal to ensure a smooth installation. 2. Provide free on-site training at the factory and second review training at the installation site; 3. The standard warranty period on average is one year. However, HYUNVAN would like to offer extra warranty period (consitions apply), lifetime maintenance.  4. We HYUNVAN can send engineers to help customers install the machines, train workers, but buyer should offer ticket charge, boarding and lodging .
3.How could you do the effect of tri-dimensional embossed?
The solid effect can be achieved by two methods:  (1) changes the printing material: achieve the embossed effect through engraving machine or material itself texture, then use our UV flatbed printer to print in contraposition;  (2)we are with 3D stereo embossed printing technology. use white inks to print several times and make them pile up, to get the relief effect.  The difference of this two methods are:  the former method allows bigger height difference of three-dimensional effect, but with higher cost;  the later with height difference limits, but can be piled up repeatedly when prints, and convenient operation technologies and coast can be controlled, but also with very good performance.


1.Accept non-standard customization ,  accept super large, super high, super heavy, cylindrical, special-shaped, super high-speed machine customization
2.Focus on the field of UV printers and carry forward the spirit of craftsmanship
3.One-stop purchase of more than ten kinds of printing formats,  6000M2 production workshop, more than ten kinds of printing formats, and 3 kinds of ultra-high-precision printing nozzles. One-stop purchase is more assured.
4.Color Accuracy- The international high-end color management system is adopted to ensure the color accuracy of each picture, and the independent ICC can be customized for you individually.
