The production date on the bags can be printed out by the inkjet printer, which is also called production date coding machine. You can buy them in offline stores or online stores.
Inkjet printer:
1, the inkjet printer is the use of electrically charged ink particles, by the principle of high-voltage electric field deflection, in a variety of objects on the surface of the printed pattern of text and digital, is a set of electromechanical integration of high-tech products.
2, the product is widely used in the food industry, cosmetics industry, pharmaceutical industry, automotive and other parts processing industry, wire and cable industry, aluminum-plastic tube industry, tobacco and alcohol industry and other fields. It can also be used for printing production date, batch number, bar code and trademark pattern, anti-counterfeiting mark and Chinese characters, which is a powerful equipment for implementing health law and promoting packaging modernization.
Types of inkjet printer:
Inkjet printer can be divided into small character inkjet printer, large character inkjet printer, laser inkjet printer, high-resolution inkjet printer, thermal transfer inkjet printer and so on. The following details of the three kinds of inkjet printers:
1, small character inkjet printer: also known as CIJ inkjet printer. Its working principle is to let a certain viscosity of the ink through the nozzle to form the ink line, by the oscillation of the crystal oscillation and the formation of breakpoints in the role of the electric field to achieve the deflection, the ink spot in the electric field before entering has been charged on demand, so that the characters can be formed on the moving objects.
2, large character inkjet printer: also known as DOD inkjet printer. Its working principle is by a row, such as 7 nozzles, 16 nozzles or 32 nozzles, etc. composed of coding nozzles let the ink in the solenoid valve under the action of the spring and the ink pressure, spray nozzles, the formation of ink spots, each nozzle on-demand inkjet that is the formation of characters.
4, laser inkjet printer: also known as laser flight marking machine. Its working principle is the role of the laser beam in the deflection mirror, on-demand in the object surface carving out characters. Can print a large amount of data in a very small range, the laser can be a very fine beam of light marking in the product material itself, the printing precision is very high, the control is accurate.
Expanded Information
Notes on the use of inkjet printer:
1, should avoid contact with the mouth.
2, no smoking near the machine.
3, wear protective glasses.
4, Wear protective gloves.
5, clean up the spattered liquid in time.
6. When testing prints, use a metal beaker and ground it.
7. Dispose of waste liquid properly.
8, in order to avoid high MEK content in the air, there should be good ventilation.
