Abstract

The invention discloses letterpress-printing dark red ink. The letterpress-printing dark red ink comprises the following components in parts by weight: 4.5-6 parts of pigment permanent red, 3-5 parts of ever-bright fast red BBN, 4-5 parts of 107 molybdate red, 10-60 parts of polyamide resin liquor, 7.6-8.4 parts of nitro-cotton liquor, 8-10 parts of alcohol, 0.5-0.8 part of polyethylene microcrystalline wax and 1.8-2.8 parts of dispersing dustproof agent. According to the letterpress-printing dark red ink and the preparation method thereof, the ink is colorful in color and luster, high in glossiness, capable of being completely dried within one second, excellent in rheological behavior and convenient for a printer to grasp and operate.

Description

technical field [0001] The invention relates to an ink and a preparation method thereof, in particular to a letterpress printing deep red ink and a preparation method thereof. Background technique [0002] Letterpress ink refers to the general term for various letterpress inks used in various letterpress printing methods. A type of ink suitable for letterpress printing, a type of ink used to print books, newspapers, albums, documents, account books, etc. The main feature of letterpress printing is that the inked part of the printing plate protrudes from the non-inked part. With the development of social urbanization, technology and humanization, printing has developed vigorously, and more and more types of printing are close to consumers' lives, etc. , followed by the increase in the use of letterpress printing inks and the emergence of problems such as letterpress printing inks being not waterproof, slow drying, low gloss, and poor rheology. Composition, it is very necess...
