Fault Phenomenon

The surface of the gold (foil-stamp) print shows a wrinkled texture, and the lamination results are poor.

 When pressed, the laminated area  feels soft and movable, and some areas may remain sticky.

Cause Analysis

1. Insufficient UV lamp curing

1. If the UV lamp output is insufficient (for example, due to UV lamp failure, obstruction, or a software issue), the UV light may only cure the surface layer of the ink.

2.  In this case, the surface of the white ink cures, while the internal ink remains semi-cured.

2. Post-curing shrinkage under ambient light

1. When exposed to natural light, the semi-cured internal ink continues to cure and shrink. This shrinkage pulls the already cured surface layer, causing wrinkling.

2. The wrinkle pattern may vary depending on the texture of the printing substrate.

3. Reduced adhesion between white ink and gold (foil-stamp) film

1. When white ink is not fully cured, its adhesion to the gold (foil-stamp) film decreases, leading to poor lamination performance.

Troubleshooting

1. Print a Test Pattern

Test File:

https://support.eufymake.com/s/article/Test-Diagram-Project-File

Important:

When printing the test pattern, use a smooth, non-absorbent substrate (such as acrylic or glass). Follow the steps below for evaluation.

2. Surface Wipe Test

Use a dry paper towel to wipe the printed surface:

• Check whether any color residue remains

• Identify which color block leaves residue, if applicable

3. Color Consistency Check

Compare the printed result with the original design:

• If color fading is observed, restore the printer to factory settings

• Re-perform ink filling and initialization, then reprint

If the issue persists after reinitialization, take clear photos of the defective print and contact eufyMake Customer Support.

4. UV Lamp Function Check

Reprint the test file and use a mobile phone to record the UV lamp during printing.

Notes:

• Wear anti-blue-light protective glasses

• Confirm that the UV lamp turns on normally and maintains stable output

5. UV Lamp Maintenance

Refer to the UV lamp deep cleaning guide and perform maintenance as instructed:

6. Verification

After maintenance, reprint the test pattern and check the result. If the issue persists after completing the above steps, please contact eufyMake Customer Support at support@eufymake.com with the following information:
