Introduction of different printing ink

Aqueous Inks. Aqueous inks were popular in the Point-Of-Purchase industry for printing posters. Most of these inks are dye-based, although today pigment inks are also available. The dye-based inks produced very vibrant colors, which were perfect for indoor applications. Printed images are quite often very close to photographic quality, which is why photographers have preferred these printers to output their work. The shortcomings of the dye-based inks were that their durability was limited and not suitable for outdoor applications. In addition, print media required top coatings to achieve good image reproduction and ensure good adhesion to substrates, such as vinyl films.
Solvent Inks. Many of the solvent inks were popular, because they provide good adhesion to vinyl films and banner substrates. These oil-based pigmented inks also provided five to seven years of outdoor durability.  These printers, however, generate high levels of VOCs and require ventilation.
Eco-solvent Inks. Eco-solvent inks were developed as a more used friendly alternative to the strong solvent inks for shops that don’t print every day. These light solvent inks, which utilize a mineral oil as a vehicle, are less likely to clog than the fast drying strong solvent inks and require less maintenance. For the most part, you can print on the same types of media that you use for the solvent inks.  There are a variety of ink sets with expanded ranges of color that are available in the eco-solvent category. These pigments inks provide good durability for outdoor applications, such as vehicle graphics, and good image reproduction for indoor applications, such as P.O.P displays, trade show and museum graphics. The downside of these inks is that they don’t dry as fast as the solvent. That means that if you need to laminate the prints, which is often the case for outdoor applications, you will need to wait for the ink to out gas, which usually requires a 24-hour waiting period before lamination.
Latex Inks. Latex inks combine the best of both worlds. Because the inks utilize pigment colorants, which provides great outdoor durability. In addition, the inks are water based, so they dry quickly, which minimizes production delays. What’s more, they adhere to a wide range of uncoated media, including paper, vinyl films, heat transfer films and banner material.  Unlike solvent and eco-solvent inks, there emit no VOCs. One problem with these printers is heat. To dry the water-based inks these systems use high heat. This can cause warping problems with heat sensitive media.
UV-Curable Inks. Another printing ink that produces extremely low VOC emissions is UV-Curable ink. When exposed to UV radiation, these inks polymerize and cure instantly. None of the ink ingredients evaporate into the atmosphere. 100% of the ink printed on the substrate remains on the substrate. The pigment is encapsulated within the cured film, which provides a heavy and durable deposit of ink. In addition to being environmentally friendly, these inks adhere to a wide range of substrates including rigid substrates and films. The quality of printing is suitable for indoor applications, such as P.O.P. displays as well as for outdoor applications, such as vinyl graphics and banners.
