Industrial chromatic printing requires another quality characteristic: flow properties. For all three characteristics – color saturation, gloss, color flow – there is one key criterion: the size of the pigment particles. The finer, the better.
The finer, the more light diffracts on the pigments and reflects the color waves to the eye of the observer; the finer, the better the ink flows, preventing the printing plates from clogging in production.
What others may tackle with grace, Bühler has elevated to a fine art. And what isn’t ground, blended, and dispersed on Bühler grinders and mixers? Wheat, rye, corn, cocoa and coffee, plastics, silver, carbon, pigments. All of these raw materials are transformed into flour, powder, dough, bulk, pastes, and inks in Bühler’s mills.
