Simple relationships can be defined between the primary particle size and structure of the pigment and final ink properties. For film thicknesses below 10 microns (typical for printing inks), the following relationships are valid:
The lower the primary particle size, the higher the optical density of the ink film.
The lower the primary particle size, the more brownish the undertone of the print.
The lower the primary particle size, the higher the viscosity of the printing ink.
The more structured the Pigment Carbon Black, the better the dispensability.
The more structured the Pigment Carbon Black, the better the hold-out but also the lower the gloss of the ink film.
