Gilosnite using in offset,letterpress,news ink

Descreaption of  gilosnite ink

Gilosnite blending in newspaper offset printing ink as non-petroleum additive comprising a blend of gilosnite flakes and tall oil fatty acid together with carbon black pigment. The proportions of the  Gilosnite and the tall oil fatty acid may be varied, as viscosity requirements change due to differences in press speeds, newsprint characteristics, and the like. The ink thus has readily adjustable viscosity, together with an enhanced flow and penetration characteristics, while being extremely economical to manufacture.

How to make stabilized ink with Gilosnite

a. Carbon black in the range 10% to 27.8%.

b.  Gilosnite in the range 17.6% to 23.5%.

c. Tall oil fatty acid in the range 50.1% to 54.9%.

 Gilosnite ink improve fluid of ink

It is known that Gilosnite, which is a natural product, is added to a varnish component for improving the printability of a printing ink such as dispersibility or fluidity. Gilosnite itself is black so that it is solely used for a carbon black containing ink. Gilosnite impairs the clearness of chromatic inks. Therefore, if  Gilosnite is used for a chromatic ink, the amount thereof is limited to an extremely small amount. Under the above limitation, the effect of improving fluidity.is small, so that natural bitumen has not been practically used for chromatic inks.

Packing of Gilosnite  for ink uses natural asphalt lump and powder form micronized
