Ink is an important material for printing, which can express patterns and characters on the substrate. Its formula is mainly made of resin, pigment, filler, auxiliary agent, solvent and other ingredients through processing.
1、 Brief introduction of water-based ink
At present, the ink on the market is mainly water-based ink. The formula is a slurry material made of water-soluble resin, organic pigment, solvent and related additives through composite grinding. Among them, water-soluble resin can be divided into water dilution type and water dispersion type. In order to improve the performance of water-based ink, various additives will be added, such as defoamer, pH stabilizer, dispersant, preservative, leveling agent, thickener and smooth agent.
2、 Photosensitive ink UV
Photosensitive ink, also known as UV ink, refers to this kind of ink that is sensitive to ultraviolet rays, and its curing method is through ultraviolet rays. Conventional UV ink products are solvent-free inks with fast drying speed, good gloss, bright color, water resistance, solvent resistance, wear resistance, good adhesion, wear resistance, corrosion resistance and weather resistance. UV curing ink and rare earth luminescent material are combined to prepare UV luminescent ink, which can make the printing process clean and environmentally friendly and low energy consumption.
3、 Formulation analysis and composition analysis technology of photosensitive UV peelable anti-counterfeiting printing water-based ink
In addition to understanding UV and water-based inks, we also need peelable and anti-counterfeiting ink products. Peelable inks are mainly used for sandblasting and shielding protection of glass, acrylic and other materials. They have the advantages of suitable adhesion, easy peeling, no residue, good flexibility, impact resistance and strong tensile ductility. Anti counterfeiting ink is a product that uses color materials and connecting materials with special functions to prevent counterfeiting.
