Flexo (Flexography) Inks are inks transferred by the process of flexography, primarily used in the printing of packing materials, for example, cardboard boxes, brown corrugated cardboard, paper bags and plastic bags, newspapers, etc. There are several types of ink which are mainly water-based, solvent-based, and UV curable. The flexo inks, like Gravure inks, have low-viscosity, characterised as fluids. This enables faster drying and, as a result, faster production, which results in lower costs. The flexo inks and method of printing continue to grow in popularity due to its low cost and environmentally friendly nature. General properties of Flexo Printing Ink Type Characteristic Use Co-Solvent Must use a synthetic resin plate that is highly resistant to solvents as it contains alcohols & esters. Makes a wider variety of resins available. Application on Al-foil, Polyolefin, Polyester Nylon, etc. Interior/exterior printing Alcohol May apply on a wide range of boards as it contains Ethanol, IPA or other Glycol that cause minimal effect to the plate. Tendency of absorbing moisture. Al exterior printing OPP, PE exterior surface printing Water Inflammable with no solvent residue. May be diluted with water. Harder to re-fuse. Limited dryness. Paper Principle of flexoprinting

Resins are the carrier of the pigment in the ink, which is the core material of the ink. Along with pigments, resins convey important properties to the printing process as part of the ink vehicle. Resins impart many important characteristics of a finished ink, including gloss and adhesion, runnability on the press, and can also help disperse pigment.   The quality of the ink will directly affect the performance of the ink, because the resin binder determines the viscosity and viscosity of the ink to a large extent. Dryness, fluidity and other properties. In order to obtain high-quality inks, it is necessary to use high-quality inks for resins. Ink resins are available in a variety of kinds, including CPP resin, Polyamide resin, Polyurethane resin, and Acrylic resin, etc. They are suitable for differenct ink system and printing material.

Requisite Properties •Printing : cylinder contamination, metastatic, electrostatic field, blocking ability •Post process : Laminate, Boil, Retort, etc. •Substance resistance : soup base, repellant, etc. •Film properties : scratch resistant, heat resistant, oil resistant Process While the press is in operation, the metal printing cylinder is partially immersed in the ink tray, filling the recessed cells, which are intaglios on the cylinder. As the cylinder rotates, it draws excess ink onto its surface and into the cells. The doctor blade removes the excess ink, leaving in the cells the right amount of ink required before it makes contact with the paper. Next, the paperboard gets sandwiched between the impression roller and the gravure printing cylinder, where the ink gets transferred from the recessed cells to the web. The purpose of the impression roller is to apply force to ensure even and maximum coverage of the ink. The inked paperboard then goes through a dryer because it must be scorched before going through the next color unit and accepting another coat of ink. Principle of gravure printing

Almost anything that you want to make it glow. You can mix it into a transparent or semi-transparent medium such as resin, wax, paint, ink, paste, plastics, rubber, fabric, caulking, ceramic glaze, nail-polish etc. There are industrial applications for safety, for novelty, for fun, for household using in arts and crafts. Glow in the dark pigment can meet expectation of all purposes above-mentioned. Some detailed applications, such as egress signs, sudden darkness orientate system, outline marking, cell phone case, keyboard cover pad, screen-printing ink, night-glow shirts, toys, clothes, glass mosaic, garden decoration lights, etc., have been applied. See some application samples in picture below: a. b.
