What type of printheads are used in One Pass systems?

One Pass systems can use different types of industrial inkjet printheads. Selection depends on speed, resolution, drop size, ink type, print width, and application requirements.

30.

Why are printheads fixed in a One Pass system?

Fixed printheads allow the printhead array to continuously cover the printing area while the substrate moves, enabling continuous stable and  high-speed printing.

31.

What inkjet control requirements does One Pass have?

One Pass requires precise control of drop consistency, droplet placement, nozzle compensation, data synchronization, and high-speed data transmission because large numbers of nozzles must operate consistently during high-speed production.

32.

Why does One Pass require advanced data processing?

At high production speeds, the system must process large amounts of image data in real time and accurately distribute that data to numerous fixed printheads and nozzles.

33. 

What substrate requirements does One Pass have?

Substrates generally need good dimensional stability, surface consistency, and transport stability. Specific requirements depend on the ink technology, application, and machine architecture.

34.

Why is precise substrate transport important in One Pass?


Because the printheads are generally fixed, substrate movement directly affects image placement. Stable substrate transport and precise motion control are therefore critical components of a One Pass system.
