<p>Abstract The invention relates to an apparatus (1) for thermal printing or embossing, comprising a film conveying section (2) for a carrier film (4) coated with a coloring agent (3), a print support (5) for a printable medium (6) and a printhead (7) for selectively heating the carrier film (4) in accordance with a predetermined printed image, so that the coloring agent (3) is transferred from the carrier film (4) to the printable medium (6) in accordance with the predetermined printed image. The apparatus (1) is characterized in that it further comprises a sensor device (9) set up for recording a remaining pattern of the coloring agent (3) on the carrier film (4) after the heating of the carrier film (4) and set up for generating a sensor signal on the basis of the recorded pattern. The invention additionally relates to a corresponding process for printed image inspection in thermal printing or embossing and to a computer program with program code for carrying out the process when the computer program is performed in a computer.</p> |
