1. Ink selection for outdoor environment applications

The outdoor application environment has relatively high requirements for the printing output materials and inks of the photo machine. First of all, the outdoor environment needs to be sun-proof and rain-proof. At this time, the choice of ink for the large format printer must also meet the conditions of these influencing factors.

Eco-solvent ink: waterproof, long-lasting, often used in outdoor advertising, banners, etc. Eco-solvent ink, or environmentally friendly solvent ink, is a high-safety, low-volatility, green and environmentally friendly ink that has been launched in the outdoor solvent-based digital inkjet market in recent years. Compared with solvent-based inks, eco-solvent inks The advantage of itq is the friendliness of the environment. Eco-solvent ink not only maintains the advantages of high-precision images produced by water-based inks, but also overcomes the shortcomings of water-based inks for their harsh substrates and the inability to apply the images outdoors. Therefore, eco-solvent inks are between water-based and solvent-based inks, taking into account the advantages of both.

UV ink: UV ink is a kind of ink without solvent, fast drying speed, good gloss, bright color, water resistance, solvent resistance and abrasion resistance. Our common UV roll printer or UV flatbed printer uses this type of ink. The ink used is ultraviolet curing, that is, when the ink is exposed to ultraviolet light, it dries up, and the resulting prints are waterproof and embossed. Energetic. Under the application of large format printer, UV ink has the characteristics of fast printing, fast curing, good color, three-dimensional image effect, and supports printing on different media layers. It is more waterproof and sunscreen than eco-solvent inks. Therefore, the application of UV ink to the large format printer is also known as the universal printer.

2. Ink selection for indoor environment applications

The application of large format printer for indoor environments is also a common printing application for color inkjet printing. The indoor environment has lower selection requirements than outdoor environments. For indoor large format printers, water-based inks are used. Large format inkjet printers using water-based inks are suitable for basic indoor printing applications such as signs, backlit display posters, and photographic works due to the transfer speed, quality and reliability of water-based inks. Water-based ink is also called dye ink. It is a completely dissolved ink at molecular level. This ink is a complete composite solution. The probability of blocking the ink head is very small. After printing, it is easy to be absorbed by the material. It is characterized by bright colors, clear layers and relatively low price. Pigment-based ink is low, so it is the best product for printing pictures and making color-jet business cards. The disadvantage is that the photo itself is not waterproof, and because the dye molecules are quickly decomposed under ultraviolet light, the color will fade within one month of outdoor use under ultraviolet light. Therefore, a protective film is usually added to the surface during production. After the protective film is applied, the photo can achieve the same complete waterproof as the oil-based ink photo, and the effect photos of different types of protective film will also show the effects of oil painting (suede), bright (bright surface), cloth pattern, laser and so on.

For different application environments, large format printers and different types of ink applications can achieve high-quality and accurate inkjet print output, which can not only meet your daily inkjet work needs, but also create greater for your inkjet business Income.
