Introduction
Ink consumption is one of the most important factors that determine the total cost of ownership in industrial inkjet printing. Whether you’re running a high-speed beverage line or printing barcodes on cartons, understanding how much ink your system uses—and why—can help reduce waste and save money.
In this article, we compare the ink consumption behavior of three primary inkjet technologies used in product marking and packaging: TIJ (Thermal Inkjet), CIJ (Continuous Inkjet), and DOD (Drop-on-Demand).

1. Key Factors Influencing Ink Consumption
Ink consumption depends on multiple technical and operational variables:
- Print content size and complexity (e.g., alphanumeric vs. QR codes)
- Print resolution and DPI settings
- Line speed and print frequency
- Nozzle size and ink droplet volume
- Ink type and substrate absorbency

2. TIJ Ink Consumption
Technology Overview:
- TIJ uses disposable ink cartridges, typically 42 ml in capacity.
- Each print is formed by thermal ejection of ink droplets from the cartridge nozzle.
Consumption Metrics:
- One 42 ml cartridge yields approximately 500,000 characters at 300 dpi.
- At high-resolution settings (600 dpi), yield can drop to around 250,000 characters.
- Best suited for short to medium runs with high precision text.
TIJ Consumption Example:
Printing a 12-character date code at 300 dpi, at 60 products per minute, a TIJ system will use approximately 15–20 ml per 8-hour shift.

3. CIJ Ink Consumption
Technology Overview:
- CIJ continuously ejects a stream of ink, only some of which is used for printing.
- Unused ink droplets are recycled, but some are lost due to solvent evaporation.
Consumption Metrics:
- CIJ printers typically consume 2–4 ml of ink per 1,000 characters (depending on drop size and font).
- In addition to ink, CIJ systems also consume solvent, with an average ratio of 1:1 to 1:3 (ink:solvent).
- Daily solvent loss through evaporation can be 10–15% of tank capacity if the printer runs continuously.
CIJ Consumption Example:
A standard CIJ setup marking 10-character codes on 100 products per minute will consume about 80–100 ml ink and 100–150 ml solvent per 8-hour shift.

4. DOD Ink Consumption
Technology Overview:
- DOD systems eject ink droplets only when required, based on user-defined print commands.
- Typically used for large-character printing on cartons, pallets, or crates.
Consumption Metrics:
- Droplet volume can vary from 80 to 250 picoliters depending on nozzle diameter.
- Consumption is calculated based on character height, print density, and print coverage area.
- Yield is expressed in square meters per liter.
DOD Consumption Example:
Printing 10 mm characters on secondary packaging (outer cartons), a DOD printer may use 5–10 ml of ink per square meter of coverage.

5. Comparative Overview
| Parameter | TIJ | CIJ | DOD |
|---|---|---|---|
| Print Precision | High (600 dpi) | Medium (100–300 dpi) | Low to Medium (60–150 dpi) |
| Typical Use | High-res text, barcodes | Small codes on high-speed lines | Large character carton marking |
| Ink Usage (per 1,000 codes) | 2–5 ml | 5–10 ml + solvent | 10–15 ml |
| Best for | Compact, clean applications | Harsh, high-speed environments | Warehousing, logistics |

6. How to Optimize Ink Usage
Tips to improve efficiency and reduce ink costs:
- Choose the lowest acceptable DPI setting for your application.
- Use fast-drying, low-viscosity inks for porous surfaces.
- Regularly maintain printheads to avoid clogging and over-spray.
- Use efficient fonts and eliminate unnecessary graphics from print layouts.
