THE ADVANTAGES OF WATER-BASED INK AND VARNISH

Waterborne ink features and advantages:

1. Non-flammable, stable ink, non-corrosive printing substrate, prevent color change, strong water resistance and rapid drying. It can not only reduce the hidden danger caused by static electricity and flammable solvents, but also reduce the residual toxicity on the printing surface, and it is very convenient to clean the printing equipment, so it is especially used in food, beverage, medicine and other packaging industries.

2. Water-based ink is a new environment-friendly printing ink with good adhesion, good softness, good elasticity, anti-adhesion, water resistance, good printing ability and high solid content.

3, water-based ink solvent for water and a small amount of alcohol, significantly reduce VOC emissions, can prevent air pollution, does not affect human health, in direct contact with the human product, such as: T-shirt and other pure cotton, elastic cloth, insole printing industry also has a very wide range of uses, is the world recognized environmental protection materials, is currently all printing ink approved by the United States Food Association of ink. Waterborne varnish features and advantages:

1, the film speed, water-borne light oil on the surface of the paper, drying methods mainly penetrate the dry, dry and volatilization in the hygroscopicity drying methods on the surface of the substrates is mainly volatile drying, but because the water-borne light oil has the characteristics of the emulsion, when the moisture content at about 30% can be closed film, there is no need to dry also won't produce the quality problems such as sticky dirty. If the infrared or hot air drying effect is better.

2, environmental protection non-toxic water-based varnish is the main component of water-based emulsion, itself does not contain VOCs, although the use of often add a small amount of ethanol to adjust the drying speed, but will not harm the health of the operator, so it belongs to the green environmental protection products.

3. Good printing adaptability of solvent-based resin of ordinary varnish exists in the form of solution, the viscosity is stable, the adjustable range is small, the adaptability of the equipment is small, and the adaptability of the equipment is poor and UV varnish needs special UV curing equipment and matching. In contrast, water-based varnish is mainly composed of water-soluble resin and water-dispersible emulsion. As long as the ratio of the two is changed, the viscosity can be adjusted flexibly. This feature makes water-based varnish can be adapted to almost all printing equipment.
