Offset printing black ink formula

Abstract

The present invention discloses an offset printing black ink formula, wherein the materials in the formula comprise resin oil, colloid oil, a long oil alkyd resin, phthalocyanine blue B, a Reflex Blue slurry, high pigment carbon black, furnace pigment carbon black, poly ethylene microcrystalline wax, polytetrafluoroethylene microcrystalline wax, cobalt isooctanoate, manganese isooctanoate, zirconium isooctanoate, butyraldehyde oxime, and high boiling point kerosene. According to the present invention, the phthalocyanine blue B, the Reflex Blue slurry, the high pigment carbon black and the furnace pigment carbon black are adopted as the ink pigment so as to provide the coloration effect; the resin oil, the colloid oil and the long oil alkyd resin are adopted as the connection material so as to disperse the pigment; the poly ethylene microcrystalline wax and the polytetrafluoroethylene microcrystalline wax are the ink filler and can be filled in the ink so as to reduce the cost; and the remaining cobalt isooctanoate, the manganese isooctanoate, the zirconium isooctanoate, the butyraldehyde oxime and the high boiling point kerosene are the additional material of the ink.

Description

technical field [0001] The invention relates to the field of offset printing, in particular to a formula of offset black ink. Background technique [0002] Offset printing is a kind of lithographic printing. To put it simply, offset printing is a printing method in which the graphics on the printing plate are transferred to the substrate by means of rubber. It is also the existence of the blanket that gives this printing method its name. Fine graphics and rich layers are suitable for mass printing, and the printing equipment can be used for multiple purposes, which is suitable for the characteristics of the Chinese label market. Ink is a very important part of the offset printing process, and different ink formulations can also determine different effects of offset printing. An offset printing ink and its preparation method with application number 201310138279.5 describe the formula of offset printing ink, but its formula only describes the number of parts of binder, wax pa...
