After the hot stamping process is complete, the C-film fails to adhere, and the printed image cannot be successfully transferred (peeled off)

1. The C-film may have been applied with the incorrect side facing down; perform a test to verify the correct orientation of the film.
2. The wrong type of C-film was used; ensure that the correct C-film is utilized.
3. The temperature setting is inappropriate; the film-transfer temperature should be set to approximately 90°C.
