1. What Is DOD Inkjet Technology?
Drop-on-Demand (DOD) is an inkjet printing technology where droplets are only ejected when needed, unlike CIJ which continuously streams ink. DOD is commonly used in large character coding, carton marking, and industrial packaging.
Two main DOD types:
-
Valve Jet DOD – Uses mechanical valves to eject large ink drops (for LCM/LCM+ printers)
-
Piezoelectric DOD – Uses electric signals to squeeze ink out via a piezo crystal (for high-resolution printing)
2. DOD Ink Characteristics
DOD ink is typically more viscous and pigmented than CIJ ink to accommodate large droplet sizes and improve visibility.
| Property | DOD Ink Attributes |
|---|---|
| Viscosity | High (for strong adhesion and jetting) |
| Drop Size | Large droplets (80–200 μm typical) |
| Colorant | Pigment-based for high contrast |
| Drying Time | Fast-drying on porous and non-porous surfaces |
| Shelf Life | 12–24 months with proper storage |
3. Common DOD Ink Formulations
DOD inks vary based on application requirements:
| Ink Type | Key Features | Best Use |
|---|---|---|
| Oil-based ink | For porous substrates like cardboard | Carton coding |
| Solvent-based ink | Quick dry, strong adhesion | Metal, plastic, film |
| Pigment ink | Bright, bold text for dark substrates | Cable, wood, automotive parts |
| UV ink | Anti-counterfeit or invisible coding | Security applications |
4. DOD Ink vs CIJ Ink: What’s the Difference?
| Feature | DOD Ink | CIJ Ink |
|---|---|---|
| Drop Control | On-demand (precise drops) | Continuous stream, deflected |
| Print Size | Large characters | Small characters |
| Viscosity | Higher | Lower |
| System Maintenance | Easier, fewer moving parts | Complex, more maintenance |
| Ideal Use | Outer case & carton coding | Product-level codes (bottles, etc.) |
5. Industries Using DOD Inkjet Inks
DOD printing is perfect for secondary packaging and bold branding:
-
Logistics & Warehousing → Shipping boxes, barcodes
-
Beverage & Brewery → Outer packaging with bold logos
-
Timber & Construction → Coding on wooden planks and pipes
-
Food Manufacturing → Case-level expiry and lot coding
-
Cable & Wire Industry → High-contrast marking on extrusions
6. DOD Printer Compatibility and Ink Brands
Most DOD systems use proprietary ink, but cross-compatibility is often available.
| Printer Brand | Common DOD Ink Codes |
|---|---|
| Videojet (LCM, 2120) | V413-DOD, V490, V498 |
| Domino (C-Series) | 1BK007, 1BK009, 1BK019 |
| Matthews | MPER-BK (porous), MSSR-WT (non-porous) |
| Diagraph | DCI Black, DCI 8000 White |
| Markem-Imaje 4020/5800 | 5196 Black, 5159 Pigment |
7. DOD Ink Application Techniques
Best practices:
-
Maintain correct nozzle height (3–10 mm)
-
Pre-test adhesion on new substrates
-
Flush lines after long idle periods
-
Use compatible cleaning solutions for nozzles and lines
8. Storage, Handling, and Safety Tips
Storage Conditions:
-
Store between 10–30°C
-
Shake before use (especially for pigment inks)
-
Seal tightly to prevent drying
Handling Precautions:
-
Use gloves during refill
-
Avoid inhaling vapors from solvent-based inks
-
Refer to MSDS for PPE guidance
9. Ink Cost and Usage
Estimated ink usage per print:
-
8–15 mL per 1,000 large characters
-
Solvent-based inks may evaporate faster — keep tightly sealed
-
Pigmented DOD inks cost more but offer better contrast
Cost-saving tip:
Use software settings to reduce drop size or print area without losing readability.
