Furthermore, technological progress has also greatly advanced the technical level of inkjet printers. Currently, the new generation of microcomputer-controlled inkjet printers is gradually phasing out the original outdated contact printing and coding methods. Its main advantages are as follows:
1. Microcomputer control makes product information flexible and easy to change, with rich content in markings.
2. The inkjet printer prints quickly, significantly improving production efficiency.
3. The print quality is clear and aesthetically pleasing, enhancing product class and making it less susceptible to counterfeiting.
4. Non-contact printing is not restricted by product shape, applicable to concave and convex or rough surfaces without damaging the product packaging itself.
5. It can be networked with management computers for unified control, which helps improve product production and management levels.
The application fields of inkjet printers are also becoming increasingly extensive, and their printing purposes mainly manifest in the following aspects:
1. Product production date, batch number, shelf life.
2. Product serial numbers, barcodes, multi-dimensional codes, trademark graphics.
3. Names of manufacturing enterprises, identification codes, etc.
4. Product specifications, models, performance, dimensions, national standard codes, inkjet printer consumables.
5. Tracking records and anti-counterfeiting information, such as random codes, electric codes, invisible codes, etc.
6. Anti-diversion regional codes suitable for modern logistics management.
According to different working principles, inkjet printers mainly fall into two categories:
1. Continuous Inkjet Printer (Continue ink jet printer), abbreviated as CIJ:
Its principle is that ink is continuously sprayed from a single nozzle under pressure. After crystal oscillation, it breaks to form ink dots; then, after charging the ink dots and high-voltage deflection, it scans and forms words on the surface of moving objects. The ink that has not been deflected into words needs to be continuously recycled using vacuum and reused. In terms of ink supply, there are gear pump ink supply type and pneumatic pressure ink supply type.
2. Drop-on-Demand Inkjet Printer (Drop on Demand), abbreviated as DOD:
Its principle is that the nozzle is composed of multiple high-speed precision valves. When printing, the corresponding valves open and close quickly according to the character type, and the ink is sprayed out relying on internal pressure, forming characters or graphics on the surface of moving objects.
