Naphthenic oils are the preferred solution for lithographic offset ink.
Nynas Naphthenics - Printing ink
- The high solvent power of naphthenic oils serves to optimise resin dissolution and pigment wetting, resulting in improved print quality, saving processing time and reducing the expenditure of energy.
- All Nynas oils comply with prevailing Health and Safety regulations.
- NYPRINT bitumen varnish is designed for black cold set inks which are ready for use upon delivery, with no additional preparation steps necessary before incorporation to the ink formulation.
The solvent power of Nynas naphthenic oils provides the manufacturer with a wide selection of resins and pigments to optimise the performance of the ink. Production efficiency and colour strength are parameters which also benefit from the excellent solvency which is a characteristic of naphthenic oils.
Nynas NYTEX® products are designed to maximise the solvency balance within ink formulations, and are available in a wide range of viscosities. The NYFLEX® range offers a lighter colour, and a higher refining degree, in order to meet the requirements of demanding formulations.
Nynas offer products for use in a wide range of offset ink formulations, including: NYPRINT™ 863 as varnish; NYTEX 810 as carrier oil; and NYTEX 4700 or NYTEX 846 as viscosity modifiers. For use in heat set and sheet-fed applications, NYFLEX 800 (BP 290-330°C) enhances the ink flexibility and NYFLEX 2120B (BP 245-275°C) offers a narrow boiling range. When combined with the very low aromaticity and high solvency of NYFLEX 2120B, these features allow for production of high quality inks which comply to eco labels such as the Blue angel standard.
