Printing ink connection material

Abstract

The invention discloses a printing ink connection material which comprises the following components in percentage by weight: 5.0-70.0% of a macromolecular polymerized PVA solution, 0.1-1.0% of a wetting agent, 0.1-1.0% of a film-forming agent, 0.1-0.8% of a dispersant, 30.0-95.0% of distilled water and 2.0-5.0% of an auxiliary agent. The used macromolecular polymerized PVA solution is a safe macromolecular organic matter, does not have toxic or side effect on a human body, has good biocompatibility, and is a common safe film-forming agent in the aspect of paper coating layers. The printing inkconnection material is simple to prepare, common and easily available in materials, low in cost, water-based and environment-friendly and can adapt to large-batch industrial production, and the quality stability of printed matters is ensured; coated paper has digital printing adaptability, can be directly printed by digital printing paper without being coated again, and can be applied to variousoccasions for improving offset printing performance of special paper, enhancing digital printing adaptability and the like.

Description

technical field [0001] The invention relates to an ink-linking material, in particular to an ink-linking material for improving the offset printing performance of special paper and enhancing the adaptability of digital printing. Background technique [0002] Special paper is also called special processing paper, which originated from the carbonless copy paper successfully developed by the National Cash Register Company of the United States in 1945. Later, other special papers were introduced continuously, broadening people's horizons and changing people's traditional views on paper. The raw materials are no longer limited to plant fibers, and non-plant fibers (such as inorganic fibers and synthetic fibers) have also been applied. Structurally, in addition to the fiber interweaving layer, the number of coating layers can also be processed or increased. In effect, it can be copied according to the design according to the needs, which was not thought of in the past. However,...

Problems solved by technology

In the printing process, too fast ink penetration will lead to slow drying speed and poor color reproduction, which will affect production efficiency and print quality; too fast conjunctiva will cause surface drying of ink during printing, and the drying speed will be slower; due to uneven surface coating Uneven mottling during ink printing directly affects the quality of printed products. Special paper will add pearlescent powder and other types of particulate materials in the coating, so that the surface of the paper has an aesthetic visual and tactile texture.

Therefore, there are also high requirements for adhesion. The adhesion of particles is poor, and they will follow the viscosity of the ink to separate from the paper itself, and then stick to the printing cylinder during transfer printing, resulting in the loss of the printing surface and resulting in extremely poor quality products.
