CMYK, CMYK + ORGB, or CMYK + FM+FY+FG+FO options

This paper discusses common issues encountered when printing fluorescent colors with DTF (Direct to Film) printers and provides corresponding solutions. With the widespread application of DTF technology in textiles, advertising, and other fields, the demand for fluorescent color printing has gradually increased. Understanding and solving these issues are essential for improving print quality and efficiency.

Introduction

DTF printing technology is highly regarded for its precision and diverse application scenarios. Fluorescent color printing, with its bright and vivid color effects, is widely used in fashion design, advertising signage, and more. However, in practice, fluorescent color printing often faces issues such as dull colors, color deviation, and blurry images. This paper aims to analyze the causes of these common problems and propose effective solutions.

1. Dull Fluorescent Colors

Causes:

• Clogged printheads.
• Poor quality ink.
• Incorrect printer settings.

Solutions:

• Regularly clean the printheads to ensure the nozzles are unobstructed.
• Use high-quality fluorescent ink from reputable brands.
• Ensure the printer settings are correct, especially the color management settings.

2. Color Deviation

Causes:

• Improper color management.
• Mismatched ICC color profiles.

Solutions:

• Calibrate the printer colors regularly.
• Use the correct ICC color profiles to ensure consistent color management.

3. Blurry or Distorted Images

Causes:

• Low print resolution.
• Unstable printhead movement.
• Poor quality image files.

Solutions:

• Increase the print resolution and ensure stable printhead movement.
• Use high-resolution image files.

4. Ink Flow Issues

Causes:

• Incorrect ink concentration.
• Excessive or insufficient humidity in the printing environment.

Solutions:

• Adjust the ink concentration to ensure proper flow.
• Control the humidity in the printing environment, maintaining it between 40% and 60%.

5. Fading of Fluorescent Colors After Printing

Causes:

• Mismatch between ink and printing substrate.
• Incomplete curing process.

Solutions:

• Use compatible ink and printing substrates.
• Ensure the curing process is complete, using appropriate curing equipment and time.

6. Rough Edges on Printed Images

Causes:

• Insufficient printhead precision.
• Uneven printing substrate.

Solutions:

• Check and clean the printheads to ensure precision.
• Ensure the printing substrate is flat and smooth to avoid print quality issues.

Conclusion

DTF printers may encounter various issues during fluorescent color printing, but these problems can be effectively resolved through proper maintenance and correct operation. The solutions provided in this paper aim to offer users a reference to improve print quality and efficiency.
