Hot stamping transfers a coating from a carrier to a substrate using heat, pressure and a die. Product families can include metallised, pigment and holographic effects, but the correct grade depends on the material and process.
Separate the effect from the engineering fit
Gold, silver, colour and rainbow effects describe appearance, not technical compatibility. The construction must match the substrate, press type, detail, coverage, overprinting or varnishing requirement and resistance target.
- Metallised
- Metallic appearance for graphical and packaging work
- Pigment
- Opaque colour for graphical or functional marking
- Holographic
- Diffractive effects for visual enhancement
- Transparent
- Clear transfer options for defined applications
Holographic does not automatically mean security
Standard continuous rainbow or decorative holographic effects can increase shelf impact but should not be presented as a customized authentication feature. Security architecture requires a separate threat and verification analysis.
Confirm before specifying
Do not publish or purchase by assumed thickness, temperature or speed. Send the current substrate, press, die, process settings, roll specification, coverage and finish requirement for technical review.
Frequently asked questions
Is rainbow holographic foil an anti-counterfeit product?
A standard rainbow effect is primarily decorative. It should not be treated as a unique authentication feature unless it is part of a defined, controlled security construction.
Can hot-stamping foil be tested before a production order?
Sample and press trials are often the safest route because substrate coating, pressure, temperature, dwell and die condition affect transfer quality.
Do you publish universal application temperatures?
No. Temperature and speed depend on the grade, substrate and machine. Final values must come from current technical documentation and trial conditions.
