These are manufactured with medium to high-structure pigment blacks. An un­pleasant characteristic of conventional newspaper inks is their low rub resistance. This can be influenced by the structure of the pigment black. Low-structure pigment blacks improve the rub resistance, those with a higher structure promote smudging. A combination of both pigment blacks is usually the solution to this problem. More carbon blacks in beaded form are now used in newspaper printing inks. Beaded carbon blacks generate little dust and therefore improve the handling necessary for an automatic ink production. The most popular of the beaded versions, including oil beads, dry beads and wet beads, is the oil-beaded carbon black, due to its relatively easy dispersibility.
