An inkjet date coder is a type of coding machine that is commonly used in the packaging industry to print product information such as batch numbers, expiry dates, and manufacturing dates on packaging materials.
The working principle of an inkjet date coder involves the use of a high-pressure inkjet system to create imprints on surfaces.
The working principle of an inkjet date coder can be divided into the following steps:
Ink Droplet Formation: The first step in the working principle of an inkjet date coder involves the formation of ink droplets. This is achieved by using a high-pressure pump to force ink through a small nozzle, which breaks the ink into small droplets.

Droplet Charging: Once the ink droplets have been formed, they are charged with an electrostatic charge. This is achieved by using an electrode located close to the nozzle to charge the droplets.
Deflection: The next step involves deflecting the charged droplets to create the desired imprint on the surface. This is achieved by using a series of deflection plates that apply an electrostatic field to the droplets, causing them to change direction.
Surface Contact: The charged droplets are then directed toward the surface that is being printed on. The droplets make contact with the surface and create the desired imprint.
Drying: Once the ink droplets have made contact with the surface, they begin to dry. The drying time depends on the type of ink being used and the surface being printed on.
The working principle of an inkjet date coder involves the formation of ink droplets, charging the droplets with an electrostatic charge, deflecting the charged droplets to create the desired imprint on the surface, making contact with the surface, and drying the ink droplets.
The high-pressure inkjet system used in inkjet date coders allows for high-speed and accurate printing of product information on packaging materials.
