Abstract

The invention discloses a printing method and device of water-base resin inkjet. The printing method comprises the following steps of: printing a printing product carrier into a printing platform, printing the water-base resin inkjet onto the printing product carrier, and heating a printing product at the temperature of 40-100 DEG C for 3-60 seconds; and after the printing platform is printed, entering a drying oven and continually heating the printing product by using the drying oven at the heating temperature of 40-200 DEG C for 3-300 seconds. The printing device comprises a printing platform and a printing spray head positioned on the printing platform, wherein a heater is arranged below the surface of the printing platform; and a drying oven is arranged outside the outlet of the printing platform. Due to the adoption of the printing method and the printing device, the defect that the water-base resin inkjet on the printing product is scratched and falls off easily can be overcome, the advantage of increasing the printing accuracy of the printing product is achieved simultaneously, the water-base resin inkjet serving as an environmentally-friendly product can be widely applied to various type of screen printing, and can be particularly applied to outdoor billboards.

Description

technical field [0001] The invention belongs to the technical field of inkjet printing, and in particular relates to a water-based resin inkjet printing method and a printing device. Background technique [0002] At present, the inkjet solvents used in outdoor print advertisements generally contain cyclohexanone, lipid components and other substances. These substances are harmful to the human body, and volatilization in the air and waste will cause environmental pollution. For this reason, people invented water-based resin ink-jet afterwards. Water-based resin inkjet is a kind of pigment ink with water as the main carrier and resin as the binder. In water-based resin inkjet, the resin can exist as a molecule or as an emulsion. During inkjet printing, after the water in the ink is gradually evaporated or absorbed, resin molecules or emulsions bind the pigment particles to the surface of the media. [0003] Water-based resin inkjet has the advantages of environmental prote...
