Water-based ink, also named Water borne ink, as the name implies, it is an ink that uses water as a solvent, and does not contain any solvents of benzene, esters, alcohols, and alkanes. It is characterized by being environmentally friendly and harmless.
Environmental protection is an inevitable trend in the development of water-based inks.
As people’s awareness of environmental protection has improved step by step, the urgent need for "environmental protection" printing materials is increasing. The national environmental protection department has always required the ultimate zero emission of VOC. In order to achieve more stringent environmental management goals, the printing industry is currently focusing on strengthening the treatment of emissions during the solvent ink printing process.
Water-based inks are especially suitable for packaging and printing products that require strict sanitary conditions. Because it does not contain volatile organic solvents, it can not only reduce the residual toxicity on the surface of the printed matter, make the printing equipment easy to clean, but also reduce the fire hazard and hidden dangers caused by static electricity and flammable solvents. Therefore, the water-based ink is called a new type of "Green" printed materials.
The market demand for high-quality water-based inks is gradually increasing
With the continuous enhancement of the display effect of corrugated boxes, the printing of corrugated boxes is gradually developing in the direction of high-grade, high-quality, multi-color, and strong visual effects. With color dot printing as the direction, it means that commodity packaging replaces transportation packaging. Replace the box-board cow card with the white cow card to achieve the characteristics of bright color, good gloss and beautiful appearance.
To meet the above standards, higher requirements for plate making and ink are put forward. The medium and high-end carton printing plate making must be based on flexographic plates. At the same time, high-quality water-based inks must be used to achieve high gloss, bright colors, fast drying and suitable for high-speed production.
At present, water-based inks are mainly used in flexographic printing and gravure printing, and occupy a large proportion in the fields of food packaging, tobacco and alcohol packaging, and children's toy packaging. The domestic production and application of water-based inks started late. Most of the packaging and printing industries use solvent-based inks, and water-based inks only account for about 7% of the entire packaging printing.
With the gradual popularity of green packaging and environmentally friendly packaging, packaging and printing products that require strict hygiene conditions such as tobacco, alcohol, food, beverages, medicines, and children's toys will gradually adopt flexographic printing. Especially in the field of packaging printing, the proportion of flexographic printing will gradually increase, so the potential domestic market for water-based inks is huge.
Regarding the ink for corrugated boxes, water-based acrylic inks are currently the most widely used.
A uniform paste-like substance composed of water-based acrylic resin binder and adding pigments, additives and other substances. The binder provides the necessary transfer performance of the ink, and the pigment gives the ink its color.
