  • Patent number: 9296909
    Abstract: An ink used for direct inkjet printing to plate based on nanometer material and a method for preparing same. Of the baseline total amount of the ink, 5 to 30 wt % is of film-forming resin, 0.01 to 5 wt % is of nanometer or micrometer dye, 30 to 60 wt % is of organic solvent, 0.01 to 5 wt % is of humectant, and water provides the balance; these ingredients are stirred and mixed at room temperature, and after the film-forming resin is completely dissolved, impurities and/or insoluble substances in the present invention are removed by means of multi-level filtering, and the obtained filtrate is the present ink. The ink in the present invention is sprayed on a metal base material surface by an inkjet printer to form a printing pattern which, after curing, can be directly printed on the machine, thus reducing chemical pollution and post-processing processes, while a press run of the printing plate can be up to 100,000 copies at a resolution of up to 175 lpi.

  • Patent number: 9127177
    Abstract: A water-based ink for use in a computer-to-plate inkjet printing and a preparation method therefor. A polymer of 5 to 40 wt %, an additive of 0.01 to 10 wt %, a dye or pigment of 0.01 to 10 wt %, an organic solvent of 1 to 30 wt %, an anti-foaming agent of 0 to 5 wt %, and deionized water are stirred and mixed at room temperature. When the polymer is dissolved, the mixed solution is filtered. The filtrate is the water-based ink. The water-based ink is sprayed via a computer-to-plate machine onto a surface of a metal substrate (which may be an aluminum plate, a zinc plate, or a copper plate) to form a graphic region. A printing plate allowing for computer-to-plate printing is acquired after solidification. The printing plate acquired is allowed to achieve a halftone dot reproduction rate between 2 and 99% and a recognition rate of 175 lpi.

  • Patent number: 9034430
    Abstract: A method for preparing a metal substrate for inkjet CTP, comprising: treating a metal substrate by anodizing or non-anodizing (such as sandpaper burnishing, sand blasting, polishing, or brushing), and then applying a hydrophilic polymer paint on the surface of the metal substrate. Due to the existence of nano-size or micron-size oxide particles in the hydrophilic polymer paint, the metal substrate has high specific surface energy, while the metal substrate has a certain roughness, therefore the metal substrate has ink absorbency and good abrasive resistance. The metal substrate can reduce the spread of ink droplets and produces print image having better resolution and definition. The non-anodizing method can avoid environmental pollution which is caused by waste acid and waste alkali discharge of anodizing method.

  • Publication number: 20140356532
    Abstract: A coating material for an aluminum substrate for inkjet computer-to-plate and preparation method and use of same. The composition of the coating material is: high polymer 5-40 wt %; nano-sized and/or micro-sized oxide particles 5-30 wt %; organic solvent constituting the remainder. The high polymer is at least one selected from the group consisting of MMA-BMA-MA terpolymer resin, phenolic resin, epoxy resin, polyurethane, polyester, urea-formaldehyde resin, polyvinyl formal, polyvinyl butyral and gum arabic. The preparation method for obtaining the coating material is to mix the ingredients together and stir at room temperature. A spin coating method or a roll coating method is used to coat the coating material onto a clean aluminum substrate having not undergone electrolytic graining and anodic oxidation treatment, and then the substrate is baked, resulting in the required roughness.

  • Publication number: 20140238256
    Abstract: Disclosed is an environment friendly waterless offset plate. The waterless offset plate is formed by: coating a base coating on a surface of a metal plate substrate not subject to electrolytic graining and/or anodic oxidation treatment but subject to oil-removal solution immersion, coating a diazonaphthoquinone light-sensitive adhesive layer on a surface of the base coating, coating an ink-repulsive layer on a surface of the diazonaphthoquinone light-sensitive adhesive layer, and further covering a polymer protective film on a surface of the ink-repulsive layer. The waterless offset plate has a good printability, and has a pressrun up to 10 to 30 thousand copies.

  • Publication number: 20130160666
    Abstract: A plate for inkjet computer-to-plate and an inkjet printing method are disclosed. The plate is obtained by coating adhesive on the surface of metallic base followed by coating ink repulsive liquid, and a polymer film can be further covered on the obtained plate as protective layer. The adhesive improves the adhesion force between the metallic base and the ink repulsive layer, and the obtained ink repulsive layer is not sticky to the printing ink during printing. Therefore, without undergoing the treatments of electrolytic graining and anodizing, the plate of the present invention can achieve excellent printing durability and high resolution, thereby avoiding serious environmental pollution of the waste acid solution and waste base solution produced in the process of electrolytic graining and anodizing.
