Non-petroleum base paper offset printing ink.

Non-petroleum base paper offset printing ink of mixed black asphalt (hard asphalt) and tall oil fatty acid and carbon black pigment. Black asphalt and the proportion of the tall oil fatty acid may be varied, as the viscosity difference requirement change according to the speed, the characteristics of newsprint, and so on. So easy to adjust the ink viscosity, along with an enhanced flow and infiltration characteristics, and extremely economical production.

The main advantage of including offset inks the ability of high speed press, low cost and eliminate oil. Dark asphalt content, may be fed to animals, indeed, the fatty acids are edible. Discovered letterpress, offset printing ink viscosity range from 20 to 1000 unique may be appropriate. Looks like 1000 unique cap signature when cylinder actual contact ink reservoir. Ink viscosity is very difficult to pump used in some of the modern media. Ink viscosity, of course, the density and thickness of the paper stock page, and the speed of the news.

The current ink, non-petroleum base, it is not dependent on oil supply reduction, environment acceptable and competitive cost and materials used in the commercial letterpress and offset printing ink. This product is recommended for nitrocellulose, polyamide, hedges, Heatset, and alkyd system, it provides a high gloss, high speed dispersibility and low viscosity. Black ink can be used to regulate the heatset and hedges. The lower limit of liquid viscosity and limit date has not yet been decided. Ink seems to be opaque oil even in a low viscosity and flow length and the oil ink.
