Offset inks the ability of high speed press, low cost and eliminate oil.

An offset printing ink in which a modified pigment is dispersed in a vehicle as a colorant, the modified pigment contains a polymer on the surface thereof and the polymer is obtained by polymerizing a resin or fat which has a polymerizable unsaturated group, and is soluble in a nonaqueous solvent, and at least one of polymerizable unsaturated monomers which are soluble in a nonaqueous solvent and insoluble or poorly-soluble after polymerization and specifically, the resin or fat is selected from the group consisting of acrylic resins having a polymerizable unsaturated group, alkyd resins which are soluble in the nonaqueous solvent, natural resin-modified phenol resins and fats.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.


Offset inks in which a modified pigment is dispersed in a vehicle as a colorant, the modified pigment has a polymer on the surface thereof, and the modified pigment is obtained by mixing a pigment. At least one of a resin or fat having a polymerizable unsaturated group, said resin or fat is selected from the group consisting of acrylic resins having a polymerizable unsaturated group, alkyd resins, natural resin-modified phenol resins and fats. And nonaqueous solvent; and adding, mixing, and polymerizing with at least one polymerizable unsaturated monomer on the surface of the pigment and wherein the polymerizable unsaturated monomer contains a polyfunctional polymerizable monomer.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.

The printing inks can be obtained by using the modified pigment as a colorant. Specifically, a printing ink, such as offset inks can be obtained by dispersing the modified pigment as a colorant in the liquid resin vehicle. The offset printing ink is prepared by using 3 to 40% by weight of the modified pigment, 45 to 97% by weight of the liquid resin vehicle, that is, the vehicle for ink, and 0 to 20% by weight of other adjuvants or an extender pigment. In addition, if necessary, well-known additives, such as a solvent for ink, a dryer, a leveling-improving agent, and a thickener can be added arbitrarily to prepare the offset printing ink.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.
