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 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 ecosolvent 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, tradeshow 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 outgas, which usually requires a 24-hour waiting period before lamination.
