How Printing Ink Manufactured In Factory???


Raw Material 

Ink Comprise two classes : 

Printing Inks

Writing Inks

90% of inks are printing inks, in which color is imparted by pigments.

The raw materials for ink production are :

 pigments, additives, binders and solvents.  Pigments- color the ink and make it frosted.  Resins- bind the ink to the surface and bind it together into a film.  Solvents- make the ink flow so it can be transferred to the printing surface.  Additives- alter the physical properties of the ink to suit different situations


Manufacturing Process The Manufacturing process involves two stages:

varnish preparation Varnish is principally a mixture of solvent, resins and additives. It exists as a clear liquid that solidifies as a thin film, wets the pigment particles and binds the pigment to the printed surface. There are two main types :

Varnishes - oleoresinous

Non - oleoresinous

Dispersal of pigments Dispersal of Pigments is essential to observe that the pigment particles do not clump together. If the clumps are formed these have to be broken up with the help of some specially designed equipments for even dispersal of pigments throughout the resin. There are three different types of equipments :

Three roll mills

Bead Mill

Cavitations mixer


Ink Color, Drying and curing characteristics 

Color :  The technology of printing ink color is based on the Young-Helmholtz theory of

three color vision which implies that white light is composed of light from a continuous spectrum of wavelengths, humans perceive only three broad bands of this light, blue, green and red light. any other color of light is borne by an appropriate combination of these three ‘primary colors’. 

Drying and curing :  Drying or curing involving a series of cross linking and polymerization reactions

that result in film formation thus binding the ink to the printed substrate. Ink drying or curing may occur by any one or by suitable combination of the following processes. ○

Evaporation

Penetration

Oxidation:

Radiation curing

Precipitation
