Small-character inkjet printer inks are generally black ink. Black ink is the matching ink for most inkjet printer customers. The reason why it is called ordinary black ink is because it represents the ink used by most of the audience.
The main component of the black ink of ordinary small character inkjet printers is graphite, commonly known as carbon powder. The purity requirement is between 99.998%-99.999%. The particle size is required to be between 0.11-0.12 microns. Exceeding the above indicators will seriously affect the ink splitting window of the printer, and cause various failures in the printer. Not only that, substandard ink will also cause serious damage to the ink system. The most obvious example is the wear and tear on the ink pump, which greatly reduces the service life of the ink pump.
Other ingredients are also strict, such as reducing agents and antioxidants. These two chemical components also require very pure purity for them, even harsh. Therefore, there are not many domestic chemical plants that can provide qualified products. Like Sinopec and PetroChina, these are domestic giants. Only their products can meet the requirements of inkjet printer inks; foreign suppliers are also giants. Like Mobil Oil and so on! Some small manufacturers also produce them. Although the price is cheap, the purity of their products generally cannot meet the requirements.
Compared with the early users’ ink standards for inkjet printers, current customers have put forward environmental protection requirements. *It was developed countries such as the European Union and the United States that made this request earlier. The EU’s ROCS standard is currently the most stringent environmental protection standard, and it imposes almost stringent requirements on printer ink manufacturers. The content of various harmful substances should be controlled within 5ppm. For this reason, inkjet printer manufacturers have invested a lot of research and development expenses to modify existing ink formulas, and a large number of chemical raw materials that meet environmental protection requirements have been used. At the same time, the ink factory has strengthened the production process management to avoid secondary pollution. In order to meet the standards, the factory also purchased a large number of expensive testing equipment, and conducted environmental inspections on each batch of products. For this reason, the cost pressure of manufacturers has greatly increased. In the selection of ink for small-character inkjet printers, Oulance recommends to choose original consumables. Whether it is the price of the inkjet printer or the later maintenance and maintenance of the inkjet printer, the original consumables are the key to reducing the failure rate of the inkjet printer.
