An up and coming book publisher wanted to run a competition encouraging budding writers to send in their work for review and possible publication. However they only wanted to open up the competition to people who had already purchased one of their books. The solution was a digitally printed self adhesive label that featured a unique code that the buyer could enter onto a microsite and submit their work. To aid in security an additional scratch off panel was printed over the code, preventing casual shoppers from copying the codes. Contact Labelservice today for samples and information on similar work.
