Abstract

Prints are produced by the offset heatset process using a printing ink based on mineral oil and additionally using an agent for increasing the abrasion resistance of the prints, where the agent for increasing the abrasion resistance is an oxidized olefin polymer which has a melt viscosity of from 100 to 15,000 mm.sup.2 /s, measured in accordance with DGF M-III 8 (75), and an acid number of from 5 to 50 mg of KOH/g of polymer, measured in accordance with DGF M-IV 2 (57).
