Non-permeable sheet substrate printing ink

Abstract

The invention relates to non-permeable sheet substrate printing ink. The ink is prepared from 10% of polymeric oil III, 3% of aluminum hydroxide, 50% of polymeric oil IV and 37% of iron blue. The ink can be used to achieve satisfactory printing effects on non-permeable sheet substrates such as plastic sheets and the like.

Description

technical field [0001] The ink technical field of the present invention, especially a kind of printing ink of non-permeable base. Background technique [0002] Offset printing is mainly used in the printing of paper and board with relatively high absorption rate. Penetration and ink condensation play a major role in the drying of most sheetfed printing. However, there are some offset printing of plastics and metal foils that use oxide conjunctiva. Dry, printing on these materials with oxidized conjunctival drying inks, printing stability and quick drying are a pair of contradictions; they cannot be skinned or stained on ink fountains and ink rollers, printing plates and blankets, but It must be able to stick effectively to the film base. In fact, in order to dry quickly, its stability time can only be reduced to the shortest possible time. In addition, the dusting of anti-adhesive agent and the reduction of stack height are also the key to avoid serious staining. The troubl...

[0002] Offset printing is mainly used in the printing of paper and board with relatively high absorption rate. Penetration and ink condensation play a major role in the drying of most sheetfed printing. However, there are some offset printing of plastics and metal foils that use oxide conjunctiva. Dry, printing on these materials with oxidized conjunctival drying inks, printing stability and quick drying are a pair of contradictions; they cannot be skinned or stained on ink fountains and ink rollers, printing plates and blankets, but It must be able to stick effectively to the film base. In fact, in order to dry quickly, its stabilization time can only be reduced to the shortest possible time. In addition, the dusting of anti-adhesive agent and the reduction of stack height are also the key to avoid serious staining. The trouble is with water-ink balance, the base is non-porous, it doesn't transfer fountain solution like paper and cardboard do, which increases the possibility of over-emulsification of the ink
