Problems solved by technology

At present, there are weak solvent and water-based plate-making inks for nano-material printing direct plate-making inks, but ink droplets will diffuse on the surface of the plate base during printing, which will reduce the precision of plate-making. Diffusion behavior to improve plate making accuracy and print quality

Abstract

The invention belongs to ink for printing plate making, relates to a material for directly making a plate by jetting ink and printing based on a nanometer material, in particular to ink for printing and directly making a plate used in a nanometer material and a preparation method thereof. The method comprises the following steps of: uniformly stirring and mixing 5-30 percent by weight of film-forming resin, 0.01-5 percent by weight of a nano-grade or micron-grade dye, 30-60 percent by weight of an organic solvent, 0.01-5 percent by weight of a humectant and the balance of water at the room temperature on the basis of the total weight of ink; and after the film forming resin is dissolved completely, performing multi-stage filtration for removing impurities and / or undissolved substances from a mixed solution to obtain a filtrate, i.e., the ink provided by the invention. The ink is jetted onto the surface of a metal substrate through an ink jet printer for forming printing patterns, and can be directly printed after curing, so that the chemical pollution and a post-treatment process are reduced, the printing resistance of a printing plate can be up to 100,000 and the resolution is up to 175lpi.

Description

technical field [0001] The invention belongs to ink for printing and plate-making, relates to materials for direct plate-making of ink-jet printing based on nanomaterials, in particular to an ink and a preparation method thereof which can be used for nano-printing direct plate-making technology (Nano-print to Plate, referred to as NTP). Background technique [0002] In the field of digital imaging, inkjet printing technology, as an important part of traditional printing technology, is attracting more and more attention. The process of nanomaterial printing direct plate-making technology (NTP) is as follows: firstly, the graphic information is processed and transmitted to the inkjet printer (plate making machine) through the computer, and the inkjet printer prints the graphic information on the coated coating or only has On the sandy, non-coated aluminum plate base, the graphics and text part is composed of nanocomposite transfer materials, which are lipophilic when printed o...
