[Technology] Do you really understand the types of environmentally friendly inks and special inks in

I believe that inthe printingand packaging industry, ink is a necessary consumable for everyone's daily production work, but printing ink is also divided into many types, do you really understand them? Today, the editor will take you to understand the types of environmentally friendly inks and special inks in the printing and packaging industry.

  Special ink belongs to anti-counterfeiting ink, which is the basis of anti-counterfeiting ink. Can be applied to packaging, advertising brochures , publications, etc. Pearlescent printing can be implemented in the main printing methods, such as offset printing, gravure printing, flexo printing and silk printing.

  There are three main components of ink: pigments, vehicles and additives.

  The pigment can provide the color for the ink; the linking material is a moist substance that can disperse the pigment evenly, such as: petroleum, water, soybean or other vegetable oils, etc.; and additives such as paraffin and petroleum fractions help to dilute and improve the printing performance of the ink. onboard performance.

  Vegetable Inks: Petroleum-based inks have been widely used for over fifty years because of their fast drying and cost-effectiveness. But the fly in the ointment is that the drying process of this ink can cause damage to the environment. Petroleum-based inks not only use non-renewable resources, but also produce VOCs during the drying process - contributing to environmental pollution and the global climate.

  Conductive silver inks: Not only is demand for silver inks still solid in traditional applications such as membrane switches and PCBs, but a number of new applications are emerging that will bring new business revenues to silver ink manufacturers.

  Nano-inks: With the increasing role of heat-sensitive flexible substrates, low-temperature curing capabilities will play an especially important role. Nano-inks have high conductivity and can be cured at low temperatures.

  Epoxy screen printing ink : Epoxy screen printing ink has a uniform and bright ink layer, good pigment dispersion, uniform fineness, good netting and leveling properties, excellent adhesion to polar substrates after curing, and high coating film Excellent hardness, gloss and good water resistance, weather resistance and chemical resistance.

  Pyrosetting ink: Pyrosetting ink is also called plastic melt ink, plastic ink, resin ink, etc. It is mainly composed of plasticizer and resin, as well as additives and colorants. Because it has the characteristic that it must be heated to cure, it does not block the screen during printing, and it can be wet-set and wet-continuously printed, which greatly improves production efficiency.

  Pyrosetting ink is a new generation of textile printing ink. Due to its many advantages, it has largely replaced traditional printing materials abroad. In addition to using mucilage and water slurry for processing under the specified requirements of the printing factory , most printing manufacturers have already understood and used a large number of thermosetting inks to process high-precision products.
