At present, the recognition of environmental protection, the ink of inkjet printer consumables needs to meet environmental protection requirements. Environmental protection inks mainly include water-based UV ink, water-based ink, UV ink and some alcohol-soluble inks.
- Water-based UV ink: Water-based UV ink is a new research direction in the current UV ink field. The preform viscosity in ordinary UV inks is generally very large, and it is necessary to add active substitutes instead. However, the currently used substitutes acrylate compounds have varying degrees of skin irritation and toxicity. Therefore, while developing low-viscosity pre-dispersed and low-toxic active substitutes, another development direction is to study water-based UV inks, that is, using ethanol and Water etc. as a substitute. Ink, has been successful, and has been applied in some printing. In addition, the alcohol-soluble ink, which is mainly used in flexo printing, is also a kind of ink with very low pollution, mainly for beverages, food, tobacco and alcohol, medicines and packaging and printing of daily necessities in contact with the human body.
- Water-based ink: The biggest difference between water-based ink and solvent-based ink is that the solvent used is water instead of organic solvent, which significantly reduces VOC emissions, prevents air pollution, is not easy to burn, does not affect human health, and has stable ink properties. Bright colors, non-corrosive plate material, simple operation, low price, good adhesion after printing, fast drying, strong water resistance, various inkjet printer consumables and inks are especially suitable for packaging and printing such as beverages, food, medicines, etc. It is recognized worldwide The environmentally-friendly printing material is also the only ink approved by the American Food and Drug Association among all printing inks.
- Ultraviolet curing ink: Ultraviolet curing (UV) ink refers to the ink that uses ultraviolet light of different wavelengths and energy to make the ink film and dry under ultraviolet radiation. Utilizing different ultraviolet spectra can produce different energy. The advantages of different ultraviolet inks are mainly: ①good gloss, bright colors; ②water resistance, solvent resistance, and good wear resistance. The monomers in the ink binder polymerize into polymers, so the color film of UV ink has good mechanical and chemical properties. The photoinitiator in UV ink is a compound that is easily excited by light. After absorbing light, it is excited into free radicals, and the energy is transferred to the photosensitive molecule or photocrosslinking agent; ③no solvent; ④fast drying speed and low energy consumption . The UV ink has become a photocuring reaction. At present, UV ink has become a relatively mature ink technology, and its emission is almost zero. In addition to solvents, UV inks also have advantages such as not easy to paste, clear dots, bright ink color, excellent chemical resistance, and low dosage.
- Water-based edible ink (applicable to various brands and models of saturn inkjet printers) is very complete. It is edible water-based ink without any harmful chemical components. It has a variety of colors such as blue, black, red, etc. Can penetrate the surface of food, various inkjet printer consumables and ink widely dispersed in the candy, ice cream, egg and other industries, while ensuring the printing effect, it also absolutely guarantees healthy eating.
- Plastic high-adhesion ink (applicable to various inkjet printer brands and specifications). The color of the ink is black and blue. It is used for food plastic packaging. The main market for such inkjet printer consumable inks is food plastic outer packaging.
- The white pigment ink is specially used for the white ink machine. It is used for printing on the surface of black and dark non-permeable materials, such as black plastic tubes, steel, tires, automobile rubber seals, wires, cables, automobile brake pads, etc. , Red, yellow, blue and other color pigment inks.
- Transparent ink (applicable to various inkjet printer brands and specifications) The color of the ink is black, and it is used for plastic surfaces coated with oil and metal surfaces with anti-rust oil.
- Alcohol-resistant ink (applicable to various inkjet printer brands and specifications) The color of the ink is black, and the object to be printed will not fade when immersed in alcohol. If it is removed from the alcohol, the additional force will be reduced when the alcohol is not completely dry. After the alcohol is completely dry, the additional force is not suffered.
- Anti-counterfeiting invisible ink (applicable to various inkjet printer brands and sizes). The color of the ink is red and blue, which can only be seen under special light sources (such as money detector lamps). The use of this ink can effectively reach the high-end food and brewing industries The anti-counterfeiting and anti-crossing goods requirements.
- Retort-resistant ink (applicable to various inkjet printer brands and specifications) The color of the ink is blue and black, and is used for food packaging. The main market for ink for inkjet printer consumables is food plastic packaging and cans.
- High-definition ink The color of the ink is black, which is used in high-definition inkjet printers.
