Toyo Ink has unveiled Toyo King HyUnity soy Kaleido; four-color process inks that expand the CMYK color gamut to nearly reach the color representation of the original RGB color range. In addition, the inks' pigment dispersion technology and highly soluble resins increase the gloss effect. These inks are certified by the EcoMark ver. 2. They contain less than 30 percent petroleum-derived solvents and less than one percent aromatic solvents.
