Abstract

An alcohol-soluble preprinting ink on gravure carton is composed of 6-10% nitrocellulose, methacrylate ester7-13%, propylene glycol methylether acetate 4-12%, dioctyl phthalate 2-6%, the dyestuff 15-25%, acetic ester 12-23%,absolute ethyl alcohol 32-43%. The ink has good glossiness, colour saturation degree and recurrence of halftone dot. It can defend the fake and resist to 180deg.C.

Description

1. Technical field: [0001] The invention belongs to an ink, in particular to an alcohol-soluble gravure carton preprint ink. 2. Background technology [0002] The traditional method of producing colored corrugated cartons is to directly use flexo printing technology to print on die-cut cartons. This method has low production efficiency, and the resulting cartons have simple patterns and dull colors, and can only be used in some low-end occasions. Later, the use of lithographic pre-printing technology to produce cartons appeared, that is, firstly, offset printing is used on the single-piece carton surface paper, and then the printed surface paper is combined with corrugated paper by a laminating machine, and then die-cut into various box shapes. . The cartons produced by this method have relatively rich patterns and bright colors, but the production efficiency is still extremely low. The biggest defect is that it cannot guarantee the stability between batches, or even the st...
