Abstract
The invention concerns an embossing plate for a hot-cold-laminating press with a three-dimensional structure based on an essentially flawless metal plate with a hardened surface of appropriate thickness and dimensions and a suitable surface, specifically a highly polished surface, into which or onto which the three-dimensional structure is incorporated by a process with at least two steps.An embossing plate produced by this process is used for the production of documents, specifically security documents, such as personal identity cards, passports, identification cards, credit cards, customer cards, driving licenses and similar sheet and/or card and/or book-like documents by means of hot-cold-lamination and/or embossing and/or item-by-item embossing.
