Common Foil Stamping Problems and How to Solve Them
Find common foil stamping problems such as poor adhesion, incomplete transfer, blurred edges, color inconsistency, and foil peeling. Ginkgotech explains possible causes and practical solutions to improve hot stamping foil quality and production stability.
The Abnormal Situation During Foil Stamping
There are many types of defects. Below provide information regards two major defects that take place very often. One is "entrapped-air" which the voids are generated and trapped on the surface of the foil. Secondly, when perform hot stamping process on exquisite items, it tends to generate foil flake.
Entrapped-air Generated During Hot Stamping Process
The voids were stuck into the film during the process. The air couldn't go out and will break during hot stamping process.
Due to its vertical working moves, this defect is often found in up and down hot stamping process.
Summary:
To adopt model number - GV series to solve this issue.
Foil Dust Generated During Hot Stamping Process
Foil dust is often found when performing hot stamping on exquisite fonts or patterns. Due to the easy release of the foil and the high working pressure / temperature, causing flake on the edge of the object which is known as foil dust.
Summary:
Choose foil with tighter velease, or adjust temperature and pressure when not changing the foil.
Gallerys
Stamped surface breaks due to the entrapped-air.
Entrapped-air.
It cost more to clean the dust, it's also hard to fully remove it.
