As the main consumables of inkjet equipment, inks, solvents and cleaning agents of inkjet printers are important consumables for inkjet printers, and are also important guarantees for stable operation of inkjet printers. For example, the promotion and development of inkjet printers and consumables in inkjet printers , Subdivided from a single consumable into a variety of consumables, such as high-adhesion ink for plastic packaging bags, anti-migration ink for wires and cables, white ink for black surfaces, anti-alcohol inks for electronic and energy-saving lamp industries, fruit surfaces and eggs for food Ink etc. The failure of inkjet printer consumables is closely related to the continuous expansion of industrial applications of inkjet printers. Only more ink varieties and application ranges can bring satisfactory applications to more inkjet printers. Ink varieties are continuously upgraded and expanded, such as plastic ink A014, high temperature removable ink A015, food oil-resistant high-adhesion ink A016, super acid and alkali resistant ink LT12, etc. Of course, there is also the special ink EC6601 for eggs, which brings different inkjet printer consumables for the application of inkjet printers in all walks of life. When it comes to inkjet printers, the environmental issues of consumables must first start with the ingredients of the inkjet printer consumables. Because the ink of the inkjet printer is fast-drying and has good adhesion, the dispersant and thinner of the consumables are often ketones and alcohols. . Because these materials tend to pollute the environment to a certain extent, and many users of inkjet printers are not aware of the impact of these used materials on the environment, especially the impact on sewers, the environmental awareness of inkjet printer consumables is not strong. . Many inks use environmentally friendly alcohol or alcohol and ketone mixtures as diluents, such as EC3103 ink, EC6101 ink, and new EC6100 sterilizing bowl transfer printing ink, which are all developed based on the concept of environmental protection. The safety of consumables in the printer is based on the above-mentioned subdivision of consumables and environmental protection. The different components and uses of various consumables put forward many requirements for the safety of inkjet printer consumables, especially with the continuous increase in applications of food companies, the safety of inkjet printer consumables has reached a new height.
