Abstract
A method of producing at least one security element () in a data carrier () comprises the steps of: Providing a source of radiation () that is configured to emit electromagnetic radiation (R), providing a data carrier () that comprises at least one guiding layer () and at least one processing layer (), providing at least one masking layer () comprising at least one masking element (), and irradiating electromagnetic radiation (R) from the source of radiation () through the masking layer () and onto the data carrier (). Electromagnetic radiation (R) that impinges on a region () of the masking layer () having no masking element () impinges on the at least one processing layer () as electromagnetic radiation having a first radiation property (Ra), whereby the at least one processing layer () is cured in said region of impingement () into a first curing state. Electromagnetic radiation (R) that impinges on a region () of the masking layer () comprising the at least one masking element () impinges on the at least one processing layer () as electromagnetic radiation having a second radiation (Rb) property being different from the first radiation property (Ra), whereby the at least one processing layer () is cured in said region of impingement () into a second curing state. The second curing state of the processing layer () constitutes the security element ().
