Printing high-quality designs on textiles requires precision in ink fixation and curing. Users of the Kornit Atlas may encounter challenges, such as ink scratching off finished prints, which can be frustrating. In this guide, we'll explore potential solutions to address ink adhesion issues, incorporating insights from experienced users.

Identifying the Problem: One user reported difficulties with ink adhesion despite employing a Fixation Agent and an ADELCO dual dryer. The user experimented with fixation levels, drying temperatures, and times, but the issue persisted, especially when working with 100% black cotton T-shirts.

Optimal Fixation Levels and Temperature: A seasoned user suggested a minimum curing temperature of 320°F (160°C) for Kornit Atlas prints, recommending a range between 320-330°F for 8-10 minutes. Deviating from these optimal temperature settings can lead to insufficient curing, resulting in poor ink adhesion.

Key Steps for Troubleshooting:

1. Review Fixation Levels: Ensure fixation levels are adequate for the chosen garment. Adjust fixation percentages based on the fabric type to achieve optimal adhesion.
2. Temperature Calibration: Verify that the drying temperature is within the recommended range (320-330°F). Inconsistent or too low temperatures can contribute to inadequate curing.
3. Drying Time Adjustment: Experiment with drying times within the suggested range, considering variations in garment types. Longer drying times may be necessary for certain materials.
4. Check for Equipment Issues: Inspect the ADELCO dual dryer for malfunctions or irregularities. Ensure proper ventilation to maintain a consistent drying environment.
5. Ink Quality and Compatibility: Evaluate the quality and compatibility of the ink used. Subpar ink formulations may impact adhesion. Consider consulting Kornit's ink compatibility guidelines.

Additional Considerations:

• Humidity Levels: High humidity can affect the curing process. Monitor and control humidity in the printing environment to optimize ink fixation.
• Maintenance Protocols: Regularly maintain and calibrate the Kornit Atlas to ensure its optimal performance. Follow manufacturer guidelines for routine maintenance.

Seeking External Support: For users grappling with persistent issues, reaching out to the community beyond the Kornit support network can provide valuable insights. Online forums, social media groups, and industry-specific events often host discussions where experienced users share troubleshooting tips.

Addressing ink adhesion problems on the Kornit Atlas involves a systematic approach to fixation levels, drying temperatures, and other relevant factors. By implementing the suggested troubleshooting steps, users can enhance their printing processes and achieve durable, long-lasting prints.
