Heat To Win
Hot promotions: ‘Heat to Reveal’ involves a black obscuring ink that hides your printed image or message, which becomes transparent when the card is heated through touch/steam.
This is an alternative way for the consumer to interact with the Product/Brand.
Utilising a reversible ink product… add additional security to this mechanic by individually wrapping the cards in printed foil if you plan to offer high value prizes via a varying prize level structure throughout the campaign.
Alternatively, you may produce a generic message to direct customers to a free phone number or website.
