Abstract
In an improved process for printing newsprint paper with a light-weight keyless printing press system the mineral oil ink standardly used is replaced by an aqueous newsprint ink having a total solids content of about 13-80% and containing about 2-30% of a colorant consisting of a pigment and/or dye, about 3-60% of a dispersed starch, and water to total 100%, wherein the percentages are by weight based on total weight of the ink. The ink may optionally contain a viscosity stabilizer if necessary to prevent retrogradation of the starch or a thickener. In a preferred embodiment the pigment is carbon black and the starch is a dextrin or waxy fluidity starch.
