Overview

The FieldPrinter uses Dusty Robotics–approved ink cartridges to create accurate, readable layout lines on a variety of jobsite surfaces.
Choosing the correct ink type for your environment and maintaining it properly ensures clear, durable prints and reduces downtime caused by clogs or fading.

This article explains the differences between water-based and solvent-based inks, when to use each, and how to store and maintain them for best results.

🧪 Ink Types Overview

The FieldPrinter supports two main ink types: Water-Based Ink and Solvent-Based Ink.

💧 Water-Based Ink

Best for:

• Indoor or high temperature environments
• Much more reliable than solvent since it doesn't dry out as easily
• Dry surfaces

Characteristics:

• Produces crisp, dark lines
• Dries cleanly with minimal odor
• Ideal for most conditions

Operating range: 30°F – 95°F (−1°C – 32°C)
Avoid: Damp, moist, or frozen surfaces

Advantages:
✅ High print clarity
✅ Excellent UV resistance (up to 3 months)
✅ Easy cleanup with water or mild detergent

Limitations:
⚠️ May bead or smear on smooth or damp surfaces (e.g. highly polished and sealed concrete)
⚠️ Not suitable for extremely cold or outdoor conditions

🧴 Solvent-Based Ink

Best for:

• Cold or slightly damp environments
• Very smooth surfaces
• High durability requirements indoors

Characteristics:

• Flows well at low temperatures
• Dries quickly for high adhesion
• Performs reliably on nonporous materials

Operating range: 25°F – 95°F (−4°C – 35°C)
Avoid: High heat and direct sunlight over 95°F

Advantages:
✅ Consistent jetting in cold weather
✅ Strong adhesion on slick or coated surfaces

Limitations:
⚠️ Thins quickly in high heat, leading to “thinning” or clogged lines
⚠️ Shorter cartridge life if exposed to sunlight or stored warm

🧰 Best Practices for Ink Handling and Storage

1. Store Correctly

• Keep cartridges in a cool, dry place (35°F – 85°F)
• Avoid direct sunlight, freezing, or heat exposure.
• Always store upright to prevent leaks and air bubbles.
   

2. Prepare Before Printing

• Allow ink to reach room temperature before installation.
• Check print quality on scrap material if lines appear faint.
   

3. Clean the Printhead

• If ink flow fades or skips, gently clean the nozzle plate with a lint-free alcohol pad, included with robot equipment.
• Avoid using compressed air or rough wipes.
• Regular cleaning prevents dried ink from obstructing jet channels.
   

⚙️ How the FieldPrinter Detects Ink Type

The FieldPrinter automatically recognizes the installed ink cartridge. You can verify what type of ink is in each print header of the robot on the iPad on the FieldPrinter tab.
This allows the system to:

• Adjust printhead temperature
• Modify jet timing and pulse rate
• Optimize ink flow for the cartridge’s viscosity.

No user input or setting change is required when swapping inks.

🌦️ Choosing the Right Ink for Your Jobsite

Additional Tips

• If you see gaps or fading, pause and clean the nozzle.
• Keep a spare cartridge in temperature-safe storage for backup.
• For summer jobs, use canopies or shade to protect the ink and the robot.
