Abstract:
The invention relates to a flat security element, having a front side and a reverse side, and being relatively small in size, such as planchettes, including, at least on one of its sides, at least one in-register authentication pattern and/or an authentication pattern resulting from the combination and/or superposition of a pattern on its front side and of a pattern on its reverse side, at least one of said authentication patterns being at least partly observable in transmitted light. It also relates to the manufacturing process thereof and to the security sheets and documents containing them.
