| 摘要 |
The invention relates to a method for producing and processing an image on a card substrate of an identification card, comprising the following steps: printing a colour image onto a surface of the card substrate by means of a printer; optically scanning the surface of the printed image and detecting individual image components of the printed image, which differ from one another in terms of their colour features, by means of an optical detection and evaluation unit; calculating coordinates of boundary lines between the detected image components, which boundary lines represent the contours of the image components, by means of a calculation unit, and heating the card substrate material in lines below the surface of a surface layer of the card substrate along the boundary lines, by moving a laser along the surface plane of the card substrate using the calculated coordinates. An identification card comprising a colour image is shown. |
