A method for producing a security document, with a thermographic substrate wherein the thermographic substrate is caused to undergo a color change depending on temperature effect in at least one first region A film element is arranged in such a way that the film element is arranged between the at least one first region of the thermographic substrate and a thermal print head. At least one first item of information is introduced by means of the thermal print head by activation of the color change in the at least one first region of the thermographic substrate, wherein the thermal print head, during the introduction of the at least one first item of information is in contact with the film element in such a way that the temperature effect causing the activation of the color change is transferred from the thermal print head through the film element to the at least one first region of the thermographic substrate.
