Offset Inks are oil-based Inks and are highly viscous. The Ink consisting of varnish system as a binder that dries either by oxidation heat evaporation or by penetration into unloaded ranger stock.

Web Offset Inks
The engineering advantage of handling a continuously running web rather than discrete sheets enables web-offset printing to cope with lower weight papers and at significantly faster speeds than ever the most productive Sheet-Fed press. This advantage can only be exploited with Inks that are capable of printing and drying at high speeds. That it should be formulated to the correct chemistry and rheology for high speed, high shear lithographic printing and for drying.

Sheet Fed Offset Inks
Offset lithography is heavily oriented towards the printing of Paper and board substitute, which process a significant degree of absorbency. This enables penetration and setting to play major roles in drying and adhesion in must sheet-fed work. However, a range of foil and plastic stocks are printed lithographically, either with oxidation drying or UU curing formulations.

These Inks are mainly low viscosity and alcohol based. This Ink can be formulated for treated or untreated Woven Sack fabrication. It can be printed by Flexographic printing technology. These Inks can be formulated for different resistant properties such as Urea resistant, Alkali resistant, Rub resistant etc. Woven Sacks bags are mainly used for outer packaging of products.

Lacquers are fully transparent solvent solution dyes based Ink specially formulated for printing on metallic substrates. A special care is to be taken by the Ink manufacturer to formulate the lacquers looking forward to the requirement of the customer. Mainly lacquers are used for food wrappers packaging. This are also used for toffees, chocolates outer wrappers. It gives very attractive look because of its transparent properties by printing of Metallic Substrate.

The traditional Water Base Ink for paper and board consists of pigmented resin system. The resin being first dispenses into water but then becomes insoluble on printed.

Water based Inks have several advantage, the first being that due to their low evaporation rate the Inks are stale on the press without drying on the stereo or in the diet giving consist Viscosity. The most extensive area for use of water based Inks is for multi wall paper sacks and corrugated case printing where non-flammability and fast drying on highly absorbent substrates are on a advantage good water resistance shortly after printing is obliging and also good level of rub resistance exerted for the case and box making machine.
