Introduction
Accurately calculating ink consumption per code is essential for cost control, production planning, and ink inventory management. Different inkjet technologies — CIJ, TIJ, DOD, and High-Resolution — have very different ways of delivering ink and therefore consume ink at different rates.
This guide explains how to calculate ink usage per print for each type of system, using practical formulas and real-world examples to help you forecast cost per product and optimize efficiency.

1. CIJ (Continuous Inkjet) Ink Consumption
Method:
CIJ printers eject a continuous stream of ink, and only part of it is used for printing. The rest is recycled or purged. Ink is consumed not only during printing but also during:
-
- Nozzle cleaning
- Warm-up/startup purging
Approximate Formula:
Typical Range:
- Standard alphanumeric code (2 lines, 15–20 characters): 0.015 – 0.035 ml
- Cost per 1000 prints: **$0.30–$0.70 USD**

2. TIJ (Thermal Inkjet) Ink Consumption
Method:
TIJ cartridges specify the number of “ink shots” (drops) they contain. You can estimate per-code use based on the coverage and DPI (dots per inch).
Formula:
Example:
- 50×25mm barcode at 300 DPI = 0.3 – 0.6 ml per print

Example:
- 42ml cartridge yields ~600,000 characters (at 300 DPI, 2x4mm characters)
- 0.07 ml per code of 20 characters
Typical Range:
- Simple text: 0.05 – 0.10 ml per code
- High-res or bold fonts: up to 0.15 ml

3. DOD (Large Character Inkjet) Ink Consumption
Method:
DOD systems dispense large-volume drops for bold characters or logos. Drop size and character height heavily influence ink use.
Estimate:
- 70mm tall code on carton (1–2 lines): 0.5 – 1.5 ml per code
Cost Estimation:
- 1L ink = 800–2000 prints depending on font size
- Cost per 1000 codes: **$0.50 – $1.50 USD**
—
4. High-Resolution (Piezo Inkjet) Ink Consumption
Method:
Used for barcodes, logos, QR codes — printing with high DPI (180–600 DPI). Ink usage depends on surface coverage and ink density.
Formula:
Comparison Table
| Technology | Ink per Code | Cost/1000 Codes | Typical Application |
|---|---|---|---|
| CIJ | 0.015–0.035 ml | $0.30–$0.70 | Plastic bottles, pouches |
| TIJ | 0.05–0.10 ml | $0.20–$0.50 | Cartons, labels |
| DOD | 0.5–1.5 ml | $0.50–$1.50 | Shipping cartons |
| High-Res | 0.3–0.6 ml | $0.60–$2.00 | Barcodes, logos |

Tips to Optimize Ink Usage
- Use thinner fonts or outline fonts where acceptable
- Reduce DPI if readability is unaffected
- Print smaller characters where compliance allows
- Schedule regular maintenance to avoid wasteful purges

Conclusion
Knowing your ink usage per code is the key to managing printing costs effectively. Different printers consume ink differently, even when producing similar outputs. At ChinaCIJInk.com, we provide accurate ink yield data and testing support to help our customers plan, budget, and scale with confidence — one code at a time.
