The application of ink according to the following aspects. Print Network HC Conducting ink Purchase , The first to consider the applicability of ink. The application of ink according to the following: 1. Printing substrate Different resin matrix to select different printing ink resin. Currently used in the printing base with BOPP film, BOPET film, BOPA film, PE film and so on. According to "similar compatibility" principle, only the matrix resin similar or close to, the printing substrate and ink will have good adhesion. In the ink system, play a key role on the adhesion of resin materials is connected. At present the development of gravure printing inks. Into benzene by solvent inks, alcohol-soluble ink formulations, ink and other water-soluble formulations. By connecting into chlorinated polypropylene resin material ink, polyurethane inks, polyamide inks. Which chlorinated polypropylene BOPP film ink applied in India; polyurethane ink applied to BOPET film, BOPA film printing, high-temperature cooking can be, boiled; polyamide ink suitable for BOPP film, PE film surface printing. 2. Printing process conditions Printing conditions including the printing speed (line speed), drying capacity, Roller performance, gravure method (Table India, in India), the number of print colors, print order, the environment temperature, humidity and so on. Conditions directly affect the transfer rate of ink drying speed and thus the economy according to reasonable conditions to use ink. Humidity at the production site for example, printing speed is high, the transfer rate to use, fast drying high-grade ink to prevent the thin film adhesion phenomena occur after printing. In air drying, the printing speed of processing conditions, use a higher viscosity, add the antistatic agent of ink, to avoid the quality problems caused by static electricity. 3. Printing effect Printing effects, including printed materials hue, gloss, transparency, cover, level, overlay precision. Different ink manufacturers in the hue, solid content, viscosity, gloss, and other levels of expression have some differences, even in the same factory, the production of different batches of ink are not the same. So, doing the same product, made in the play's comp after customer approval, the same batch as one-time purchase enough ink to ensure consistency with the comp. 4. Postpress conditions Plastic film by printing, the go through extrusion compound, dry lamination, vacuum aluminum plating, slitting, bag making and other processes, even when the customer using high temperature steaming, boiling, freezing, sterilization, etc. treatment. Therefore, according to Package After printing the material, technological conditions, conditions in the selection of ink. Such as during dry compound, we should consider printing inks and adhesives in the adaptability of the product without affecting the peel strength of the composite. Conducting bag, high temperature steaming, boiling, freezing, processing, surface printing ink to be considered high resistance, low temperature, to prevent the ink from the film, color and so on. 5. Customers use Ink as the pigment, additives, binders, fillers, and chemical composition of solvents and other organic systems, formed by the printing ink attached to the plastic film substrate. As a variety of packaging materials, not only play the role of marketing to attract eyeballs, but to play to ensure product quality, the role of the safety of consumer protection. Thus the selection of the first ink ink to consider the health, safety, and tasteless, its resistance to resistance to meet the customer's use. Resist the ink, including light resistance, heat resistance, oil resistance, chemical corrosion as well as the packaging has good compatibility and so on. Surface printing ink to rub, oxidation resistance, resistance to water, light, and have some antistatic properties. Resist the ink to meet the added non-toxic additives to health; no need to add filler requirements without.
