Hand warmth
Applications
Anti-counterfeit and tamper
A hidden mark that appears under a warm thumb is easy for customers to check and hard to copy with ordinary print. A tamper version changes colour when torn.
01
Hidden logos and codes for cosmetics, wine and electronics
02
Tamper-evident seals that change colour when removed
03
Combinable with other security print
We help place the mark and the "rub to verify" prompt where customers will see it.
