What Is Drop On Demand Printing?
Drop on Demand (DOD) is an inkjet printing method where ink droplets are ejected only when needed, unlike Continuous Inkjet where a constant stream is produced.
Types of DOD Printers
- Thermal DOD: Uses heat to push ink droplets through nozzles.
- Piezoelectric DOD: Uses piezoelectric crystals to create pressure and eject droplets.
Advantages of DOD
- Lower ink consumption
- Sharper, higher-quality prints
- Precise control over droplet placement
- Ideal for large characters or barcodes on cartons
DOD printers are commonly used in packaging, shipping, and product labeling industries.
