Pigment Blacks for Printing Inks

The use of suitable pigment blacks makes it possible to achieve various effects  

Almost 100% of the pigment black applications in the printing ink industry involve the dyeing of black inks. Pigment blacks are also used to tint gray and colored inks (brown, oUve, etc.), but this amount is relatively small compared with the entire consumption. 

Bearing in mind the effects which may be achieved by pigment blacks in printing inks, one can distinguish between the color giving (inking) component and the rheological 

The inking component depends largely on the particle size of the pigment black. The liner the particle size of the pigment black, the higher the color density or jetness of the printing ink  

Decreasing the particle size, increasing jetness and brown undertone Increasing the particle size, decreasing jetness and bluer undertone
