Even the most advanced digital textile printers can occasionally face print quality issues — from color mismatches and banding to nozzle blockages or misalignment. These small but significant print defects can cause production delays, material waste, and inconsistent results.
At Grando, our field technicians have encountered and resolved hundreds of such challenges in real-world production environments. Drawing from their experience, this guide focuses on troubleshooting print defects with practical, field-tested methods. Whether you’re dealing with color banding, nozzle check issues, or printer calibration errors, these expert tips will help you identify, correct, and prevent common problems — keeping your prints flawless and your production running smoothly every time.
Troubleshooting Print Defects: Fix Color Banding or Uneven Lines
Common Causes:
- Clogged print heads
- Low ink pressure
- Incorrect print resolution
Solutions:
— Perform a nozzle check and clean the print head to clear any blockages.
— Ensure ink cartridges are full and properly pressurized.
— Recalibrate the printer to ensure accurate droplet placement.
— Always use genuine Grando-approved inks for consistent results.
A consistent color banding fix routine keeps your output smooth and professional, especially during high-volume textile production.
How to Resolve Color Mismatch Across Prints
Common Causes:
- Improper ICC profiles
- Incorrect media or fabric settings
- Environmental inconsistencies
Solutions:
— Always use the correct ICC color profile for your specific fabric type.
— Regularly calibrate your printer’s color management system.
— Maintain stable temperature and humidity levels in your workspace to prevent ink drying inconsistencies.
Accurate printer calibration ensures that every print matches your intended color palette, from the first sample to the final run.
Fixing Ink Smudging or Ghosting in Prints
Common Causes:
- Incorrect curing temperature
- Excessive ink saturation
Solutions:
— Adjust your heat press or dryer temperature based on the fabric type.
— Reduce ink load settings in your RIP software to optimize drying time.
— Use Grando Sublimation Paper Rolls, designed for faster drying and sharper print clarity.
Proper curing and material selection prevent ghosting and keep prints crisp and durable — a key step in sublimation printing troubleshooting.
How to Solve Misalignment and Blurry Prints
Common Causes:
- Print head misalignment
- Fabric slippage during feeding
Solutions:
— Conduct regular alignment tests to fine-tune the print head position.
— Keep rollers clean and check for wear or damage.
— Activate your machine’s auto-feed tension control to prevent fabric movement during printing.
Following these printer alignment tips helps eliminate blurriness and ensures your designs print with perfect precision.
