ABSTRACT:
Glazing on printing press rollers is reduced by use of a lithographic printing ink containing a crown ether such as the cyclic polymeric hexamer of ethylene glycol. The incorporation of the crown ether in the ink is especially helpful in reducing glazing when using lithographic inks wherein the underlying pigment contains calcium, e.g. Calcium Lithol Rubine - Pigment Red 57:1.
