Dwell Time and Machine Speed in Hot Stamping
Machine speed and contact time have a direct effect on hot stamping quality. A setting that works during a slow trial may become unstable when the machine runs at normal production speed. ## Why Contact Time Matters Contact time is the moment when the heated stamping plate, foil and paper surface stay together. If this time is too short, the foil may not activate fully. The result can be incomplete transfer, weak adhesion or broken fine details. If contact time is too long, the foil may over-transfer. Edges can become less clear, gloss can look dull and the stamped design may appear heavy.…
