Eco-friendly flexo inks

Solar Inks, specialist supplier of inks for flexographic and screen printing, has launched Earthinks, a range of environmentally friendly water-based flexographic and screen printing inks.
These inks have been developed from sustainable and non-polluting resources including soy, starch, sugars, dextrin, tree resin, cellulose and other polysaccharides. Natural waxes are used to replace standard petroleum-based synthetics, and natural oils are used to defoam instead of mineral oils. Earthinks are glycol and silicone-free, contain no heavy metals and have near-zero VOC levels.
The inks have low viscosity and low foaming levels which, according to Solar Inks, deliver sharp images with lower dot gain than standard inks. They use unique pH-independent technology. It should also be possible to mix colours in-house for those printers and converters produce spot colours on-demand.
According to the Solar Inks press release, Earthinks can be used on a wide variety of substrates to print corrugated and flexible packaging, labels, envelopes and a full range of papers from till rolls and paper cups to paper bags and gift wrap, including recycled stocks.
