Internal structure of continuous inkjet printers
This section explains the internal path and ink circulation principle of industrial inkjet printers.
Stores the ink used in printing. Ink recovered from the gutter is also returned here.
Pressurizes and feeds the ink from the main tank to the print head.
3Pressure reducing valve
Adjusts the ink pressure.
Oscillates the ink stream discharged from the nozzle to separate into ink particles.
Discharges the ink.
6Electrostatic electrode plates
Applies a negative electric charge to the ink particles created from the ink stream.
Monitors whether the ink particles have the proper electrostatic charge in them.
8Deflecting electrode plates
Generates a magnetic field between the electrode plates to deflect ink particles according to their charge. This directs ink particles onto the print target.
Collects the ink particles that are not used in printing.
Retrieves the ink particles from the gutter and feeds them to the main tank.
Repeats the ink circulation.
- Solvent tank
- Supplies solvent to control viscosity when the ink in the main tank becomes too thick.
- Ink tank
- Supplies ink to the main tank when it is empty or when the ink is too thin.
