Special inks are anti-counterfeiting inks, which form the basis of anti-counterfeiting inks. Can be used in packaging, advertising pictures, publications, etc. The main printing methods, such as offset printing, gravure printing, flexo printing and silk printing can be implemented in pearl printing.
So far, we have seen various special inks appear one after another in the market, printing their respective effects. This article will discuss several inks that are likely to occupy a certain market in the future market and lead the trend. .
Vegetable ink
The three main components of ink: pigments, binders and additives.
Pigments can provide color to the ink; the binder is a moist substance that can evenly disperse the pigment, such as: petroleum, water, soybean, or other vegetable oils; and additives such as paraffin and petroleum fractions help to dilute and improve the ink in printing Onboard performance.
Petroleum-based inks have been widely used more than fifty years ago because they have the advantages of fast drying speed and high cost efficiency. But the disadvantage is that the drying process of this ink will cause damage to the environment. Petroleum-based inks not only use non-renewable resources, but also generate VOCs during the drying process-causing environmental pollution and global climate.
Conductive silver ink
In the next eight years, the conductive silver ink market will nearly double, reaching $ 2.4 billion by 2015.
Not only is the demand for silver ink from traditional applications such as membrane switches and PCBs still solid, but a number of new applications are gradually taking shape, and they will bring new business revenue to silver ink manufacturers. First, the radio frequency identification market will contain the greatest opportunities for development. It is estimated that by 2015, the revenue of silver ink used only for RFID antennas will exceed US $ 880 million. In 2003, the sales volume of electronic tags in the world was 1.5 billion tons, and it is expected to reach billions of tons by 2007, and at least 5 billion tons after 6 years. Although it is still unpredictable, when the demand reaches billions of tons At that time, what proportion of electronic labels produced by printing factories using electronic ink and existing printing equipment will occupy.
Second, because the current alternative energy market contains a very favorable objective development environment, it is expected that by 2015, the silver ink revenue for solar panel contacts will increase to about 250 million US dollars.
Nano ink
As the role of heat-sensitive flexible substrates expands, the low-temperature curing function will play a particularly important role. Because nano inks have high conductivity and can be cured at low temperatures, by 2015, nano ink sales will account for nearly 21% of total ink sales. .
Epoxy screen printing ink
The ink layer of the epoxy screen printing ink is uniform and bright, the pigment dispersion is good, the fineness is uniform, the mesh is good? The leveling is good, after curing, it has excellent adhesion to polar substrates, the coating film has high hardness, gloss and Good water resistance? Weather resistance? Chemical resistance.
Industry insiders said that it should be noted that: add appropriate amount of thinner before use to mix thoroughly; use special thinner for different types of ink; mass production after trial printing to confirm that it meets the requirements; do a good job of removing grease and impurities on the surface of the printed object In order to promote the effect of adhesion; static electricity on the surface of the screen or the printed object will cause pinholes in the ink after printing; too high environmental humidity will affect the printing effect; after the product coating is dry, it can be laminated for shipment; operation After the completion of the remaining ink, close the container tightly; when the printing quality is in bad condition, please consult the technical department of our company, do not handle it by yourself; no compensation for improper use. In particular, pay attention to safety rules: Ink and thinners are strictly prohibited from pyrotechnics during use and storage. When using, pay attention to the good ventilation of the construction site. Try to avoid direct skin contact. Inadvertent splashing of the mouth? Nose? Eyes? Directly consult a doctor. Allergists should apply a layer of skin cream or impervious gloves before use.
Thermosetting ink
Thermosetting inks, also known as plastic melt inks, plastic inks, resin inks, etc., are mainly composed of plasticizers and resins, as well as additives and colorants. Because it has the characteristic that it must be heated to be cured, it does not block the screen during printing, and can be printed continuously from wet to wet, which greatly improves the production efficiency.
Thermosetting 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 the use of glue and water slurry for processing under the requirements of some customers, most printing companies have already understood and used a large number of thermosetting inks to process high-precision products.
In China, agents for thermosetting inks were distributed a few years ago, such as Guangzhou agents of Canadian LANCER company, American WELFEX company, and Italian KFG company all set up distributors on the mainland. At that time, because domestic printing manufacturers were used to processing products with glue and water slurry, and the processing technology and equipment were backward, plus the agents only promoted ink during the promotion period, and there was no matching equipment and color separation platemaking technology. Therefore, it is impossible to meet the needs of customers to produce high-precision products from the configuration of production projects.
Now, there are also some professional printing design companies in China, which largely meet the needs of customers for design and plate making. And because of the improvement in precision of manual and automatic printing machines, it also provides conditions for the popularization of thermosetting inks in China.
