Abstract

The invention provides offset ink and a preparation method thereof, and belongs to the field of offset printing. The offset ink comprises the following components in parts by weight: 65-80 parts of connecting materials, 1-2 parts of cerate, 15-25 parts of pigments, 0.1-0.3 part of anti-skinning agents and 1-10 parts of auxiliary agents A, wherein the cerate comprises flax oil, mineral oil and bee waxes; and the bee waxes contain polar and non-polar groups, carbon chains are unequal in length, and thus the cerate has both internal lubrication action and external lubrication action. Above all, the offset ink provided by the invention effectively solves the problem that the offset ink is adhered with an ink roller under the precondition of not influencing gelation because the prepared cerate is discovered to equilibrize the internal and external lubrication action under the combined action of the flax oil, the mineral oil and the bee waxes, and can effectively enhance the printing quality, reduce the cleaning and maintaining cost of a printing machine and increase the working efficiency of the printing machine; and the preparation method provided by the invention has the advantages of simple preparation step and low process cost.

Description

technical field [0001] The invention relates to an offset printing ink and a preparation method thereof, belonging to the field of offset printing. Background technique [0002] With the progress of the printing industry, the continuous improvement and improvement of printing technology and printing equipment, offset printing has been favored by its unique advantages, such as fast and convenient plate making, low cost, high printing quality, wide range of paper use, and large printing quantity shrinkability. Favored by printing manufacturers at home and abroad, it has developed rapidly and extensively, and then occupies a leading position in the international printing industry, and offset printing ink has also developed rapidly. [0003] As the most important printing material for information reproduction, ink should have good printability during printing. Offset printing ink is mainly composed of colored pigments (dyes, etc.), binders, fillers and additives. When preparing...
