Nowadays the number of medicine packaging counterfeits increases very quickly. The rotogravure printing technique is worldwide used for medicine blister foils production. However, the existing anti-counterfeiting solutions do not take into account this printing process. Additionally, it is not easy to apply conventional solutions while using blister foils instead of uncoated/coated paper. In this paper, we study some features of the rotogravure printing and identify the future paths to fight the increasing number of counterfeited medicine products. We present the result of a preliminary study of such a process, extended to foils, and discuss some promising solutions for blister foils authentication.
