Abstract

The invention disclose water-base type printing ink for spray ink printing, which comprises the following components in percentage by weight: 3-5 percent of dye, 0.65-2 percent of surfactant, 0.2-2 percent of polymer, 0.5-0.8 percent of additive and the balance of solvent, and the sum of the mass percent of the components is 100 percent. The water-base type printing ink for spray ink printing hasthe advantages of good fluency, better storage stability, no sediment, high printing color density of solid color lump, bright color, high saturation, no corrosion for blocking a spray head, water resistance, low price, simple preparation method and no harm to human body because water accounts for 60 percent of the components of the printing ink. By adopting the water-base dye type printing ink for spray ink printing, printed pictures and characters are clear, and the phenomena of splashing and water bleeding staining can be avoided.

Description

technical field [0001] The invention belongs to the technical field of inkjet printing, and in particular relates to a water-based dye ink used for inkjet printing. Background technique [0002] As an emerging printing method, inkjet printing is developing rapidly, and the corresponding inkjet printing consumable materials are also developing rapidly. Ink is an important part of printing consumables, and its quality directly affects the quality of inkjet printing. The research and development of ink itself is a part of inkjet printing technology. Only inks that meet certain standards can ensure good visual reproduction of inkjet printing pictures. Nowadays, there are many printing consumables produced at home and abroad on the market, but the quality is uneven. The main problems are that the ink is too permeable, there are marks on the back, bleeding on the edge of the ink, and poor water resistance. Contents of the invention [0003] The purpose of the present invention...
