The Rapid Development Of Printing Ink
Oct 26, 2017

In recent years, with the rapid development of the printing industry, all kinds of plastic, paper packaging printing continuously improve the product packaging level more and more demanding. Composite flexible packaging printing is different from the general packaging, that is, the former is printed, the latter is the table printing, the ink used in the two is called the ink and the printing ink, we must analyze the differences between the two inks, the correct use of them has great significance.Printing Ink

Most of our inks are made up of $number binders, $number pigments, $number organic solvents and 0%~5% additives. Binders are adhesive resin, is the ink off the chain component, the pigment and the printed material bonded in a piece, the adhesion effect, and make the ink shiny. Pigments determine the color type. The solvent dissolves the resin, regulates the viscosity, regulates the drying speed and enhances the wetting effect to the printing material. Additive is to improve viscosity, weathering resistance, anti-aging, increase luster and other functions.Printing Ink

The main solvents used in the printing inks are xylene and isopropyl alcohol. and the general printing ink solvents to toluene, ethyl acetate mainly. High temperature cooking ink is ethyl ketone, ethyl acetate, etc. mainly. In printing ink solvents for high-speed printing, solvent volatile faster, solvent residue is particularly low. Because polyamide resin soft, with greater flexibility, adding additives to make its wear resistance is good and improve, and external objects collide more firmly. Printing ink resin chlorinated polypropylene resin is particularly good rigidity, wear resistance, because it is in India, wear resistance requirements are correspondingly lower.Printing Ink

Table printing inks and printing ink because of the different links, and its accessories? Additives and additives are also not the same, the table printing inks often add dehydrated apples, kiwi fruit acid ester, to improve adhesion, increase luster, improve viscosity. Printing inks also include various pigments dispersant, enhancer, defoaming agent and other additives.Printing Ink
