Water Base Inks By Siddhi Inks Corporation

Being a customer centric organization, we are involved in trading and supplying a supreme quality range of Water Base Inks in Daman, Daman and Diu, India.

Water-based or water-borne inks first came into use for flexography in the 1940s and are used most commonly with absorbent substrates such as newsprint, pressure sensitive label stock and corrugated board. Water-based inks dry on these substrates by a combination of evaporation and absorption into the paper.

Water-based inks are composed of pigmented suspensions with water soluble resins and/or resin emulsions. Typically, water-based inks have a higher percentage of solids, which means that there is less liquid to be removed. Due to the nature of the resins available in water systems, a thinner layer of ink is often used. When water is combined in an azeotropic mixture with certain solvents, the evaporation can be accelerated. These factors can reduce the demands put on the ink dryers, if they are present on the press. Ink dryers are hot air high velocity ovens that use air to remove the water and co-solvents from the printed ink film.

Gas forced-air and radiant heat dryers, which may consume significant amounts of energy. Even more energy is required to dry the water-based ink when printing on less porous substrates (i.e., film). Water has a much greater latent heat of vaporization (low vapor pressure or evaporation rate) than typical flexographic organic solvents.
