Special inks belong to anti-counterfeiting ink, which is the basis of anti-counterfeiting ink. Can be used in packaging, advertising brochures, publications, etc. The main printing methods, such as offset printing, gravure printing, flexo printing and screen printing can be implemented in pearl printing.
Vegetable ink
The three main components of ink: pigment, binder and additive.
Pigments can provide color to ink; A binder is a wet substance that can disperse the pigment evenly, such as oil, water, soy or other vegetable oils; Additives such as paraffin and petroleum fractions help to dilute and improve the performance of the ink on the press.
Petroleum-based inks were widely used more than 50 years ago because of their rapid drying speed and high cost efficiency. 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 - causing environmental pollution and global climate.
Conductive silver ink
Not only is the demand for silver inks for traditional applications such as film switches and PCBS still solid, but a number of new applications are gradually forming, which will bring new business revenue to silver ink manufacturers.
Nano-ink
With the increasing role of thermal sensitive flexible substrates, the low temperature curing function will play a particularly important role. Nano inks have high conductivity and can cure at low temperatures.
Thermosetting ink
Thermosetting ink is also known as plastic melting ink, plastic ink, resin ink, etc., mainly composed of plasticizers and resins, and other additives and colors. Because it has the characteristic that it must be heated to cure, it does not plug the net when printing, and can be wet wet continuous printing, which greatly improves the production efficiency.
Thermosetting ink is a new generation of textile printing ink, because of its many advantages, has largely replaced the traditional printing materials in foreign countries. In addition to the use of glue and water paste for processing under the specified requirements of the printing plant, most printing manufacturers have understood and used a large number of thermosetting inks to process high-precision products.
