2. 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

3. 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

4. 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
