Messages printed with thermochromic inks tend to disappear on application of certain degree of heat and it reappears when the heat on substrate cools down. Such property attribute to the name Magic Message. The heat can be generated simply by rubbing the surface of a label on which thermochromic printing is inscribed so the printed message disappears from the label face. But almost immediately on stopping the rubbing the message reappears on the label face. Such printing can be done on any kind of labels be it holographic, paper or polymer or any other substrate generally.
Messages printed using Ultra-Violet (UV) inks are generally not visible to human eyes under normal condition. It is only when the item with UV printing on it is passed under a UV light or similar decoders that the Invisible Message becomes visible. Such printing can be done on any kind of labels be it holographic, paper or polymer or any other substrate generally.
