The Abnormal Situation During Foil Stamping
Incomplete stamping effects lead to missing parts and a black stripe appears on the foil.
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.
