Common Issues and Solutions When Printing with Crystal Label AB Film

Crystal Label AB Film is widely used in UV DTF (Direct to Film) printing for transferring high-quality designs onto smooth surfaces such as glass, metal, plastic, and ceramics. While it offers excellent adhesion and vibrant color reproduction, users may encounter some common issues during printing. Below, we outline these challenges and provide solutions to ensure optimal printing results.

1. Ink Not Adhering Properly to A Film

Possible Causes:

• Low-quality or incompatible UV ink

• Incorrect curing settings on the UV printer

• Dirty or oily surface on the A film

Solutions:

• Use high-quality, compatible UV ink recommended by the film manufacturer.

• Adjust the UV curing settings to ensure proper adhesion.

• Clean the A film surface before printing to remove dust, oil, or other contaminants.

2. Blurry or Smudged Prints

Possible Causes:

• Ink layer is too thick

• Printing speed is too high

• Poor-quality A film

Solutions:

• Adjust the ink settings to apply an optimal thickness.

• Reduce the printing speed for better precision.

• Use high-quality A film with a smooth and even coating.

3. Poor Adhesion Between A and B Film

Possible Causes:

• Low pressure during lamination

• Misalignment of A and B films

• B film adhesive quality issues

Solutions:

• Increase the pressure when laminating A and B films together.

• Ensure proper alignment before applying the B film.

• Use high-quality B film to achieve strong adhesion.

4. Film Peeling Off After Transfer

Possible Causes:

• Insufficient pressure during application

• Incomplete curing of UV ink

• Surface incompatibility with the target material

Solutions:

• Apply consistent and firm pressure when transferring the design.

• Ensure the UV ink is fully cured before peeling off the film.

• Test the compatibility of the film with different surfaces before full-scale production.

5. Bubbles or Wrinkles Appearing in the Film

Possible Causes:

• Trapped air during lamination

• Uneven application of pressure

• Environmental factors such as humidity and temperature

Solutions:

• Use a squeegee or roller to remove trapped air during lamination.

• Apply even pressure across the entire surface.

• Store and process the film in a controlled environment with stable temperature and humidity.
