Problems solved by technology

This method increases the production cost
And although in CN101081952, photosensitive coating has been removed, the plate base must be processed through special electrolysis and oxidation processes, which increases the difficulty of the universal use of the plate base, and the water-based ink in this invention is hydrophilic, has nanometer and The surface of the aluminum substrate with micron pores is prone to dirtying under the action of capillary force

Embodiment 1

[0027] Preparation of coating: 0.1wt% gum arabic, 5wt% potassium sulfate, 10wt% zinc oxide nanoparticles with a particle size of 10nm, 0.1wt% organosiloxane, 0.2wt% propylene glycol ester and the remainder mixed with water at room temperature, stirred the mixed solution, and filtered to remove impurities to obtain a water-soluble paint.

[0028] After the electrolytic graining and anodic oxidation treatment of the aluminum base is washed and dried, the water-soluble coating obtained above is evenly coated on the surface of the aluminum base by spin coating, and dried. The thickness of the coating is about 1 μm. A plate material for inkjet printing direct-to-plate is obtained.

Embodiment 2

[0030] Preparation of coating: mix 20wt% polyethylene glycol, 0.1wt% aluminum sulfate, 0.1wt% aluminum oxide nanoparticles with a particle size of 1000nm, 20wt% water and the rest of ethanol at room temperature, and stir the mixed solution , to obtain a water-soluble paint after filtering to remove impurities.

[0031] Use 5wt% dilute sodium hydroxide aqueous solution to degrease the aluminum substrate that has not been electrolytic grained and anodized, wash and dry it with water, and apply the above-mentioned aluminum substrate evenly on the surface of the aluminum substrate by roller coating. The water-soluble paint is dried, and the thickness of the coating is about 20 μm to obtain a plate material for direct plate-making by ink-jet printing.

Embodiment 3

[0033] Preparation of coating: 10wt% polyacrylamide, 0.2wt% zinc chloride, 1wt% calcium carbonate nanoparticles with a particle size of 200nm, 0.05wt% polyether, 0.2wt% ethylene glycol ester, 0.3wt% of malic acid, 30wt% of water and the rest of ethanol are mixed at room temperature, the mixed solution is stirred, and the water-soluble paint is obtained after filtering to remove impurities.

[0034] Use 5wt% dilute sodium hydroxide aqueous solution to degrease the zinc plate base that has not undergone electrolytic graining and anodic oxidation treatment, after washing and drying, apply the above-mentioned zinc plate base evenly on the surface of the zinc plate base by spin coating to obtain The water-soluble coating is dried, and the thickness of the coating is about 5 μm, so as to obtain a plate material for direct plate making by inkjet printing.

Abstract

The invention belongs to the field of printing plate materials, and relates to a printing plate material for ink-jet printing direct-to-plate. Paint is coated on the surface of a metal plate after electrolytic graining and / or anodic oxidation treatment or without electrolytic graining and / or anodic oxidation treatment or a plastic plate after graining to prepare the printing plate material applicable to ink-jet printing direct-to-plate. Diffusion of ink droplets of plate making ink is effectively controlled by coating the paint on the surface of the metal plate or the plastic plate, so that plate making accuracy is improved. When the printing plate material is used, graphic and text information is printed on the printing plate material to form a graphic and text area by an ink-jet printing plate making machine through solvent plate making ink. By the aid of the printing plate material, production cost is reduced, staining in printing is avoided, and a printed matter with excellent image resolution can be obtained after the printing plate material with the graphic and text information is printed on a computer.

Description

technical field [0001] The invention belongs to the field of printing plates, in particular to ink-jet printing plate-making plates, and more specifically to metals that have undergone electrolytic graining and / or anodic oxidation treatment, or that have not undergone electrolytic graining and / or anodic oxidation treatment. Plates, or inkjet printing direct-to-plate plates obtained after coating the surface of grained plastic plates with paint. Background technique [0002] Inkjet printing plate-making technology has gradually attracted the attention of people in the industry because of its environmental protection and simple operation. In CN1818786, the inkjet printing method is used to print the ink on the aluminum plate base of the common positive PS plate coated with the inkjet receiving layer for plate printing. This approach increases production costs. And although in CN101081952, photosensitive coating has been removed, the plate base must be processed through speci...
