Therefore, an ink layer that changes color is provided, and in the former case, the surface where the ink layer burns is exposed on the base (paper) surface. In other words, printing is performed according to the color and strength of the base and ink layers. Note that the color of the ink layer uses a dark colored ink that does not reflect the laser light.

Abstract

L'invention concerne des techniques pour vérifier que l'information a été imprimée par une imprimante laser. On vérifie que l'information a été imprimée sur une surface d'impression, sur la base d'un produit logique d'un signal d'oscillation détecté représentatif du bon état ou du mauvais état des oscillations d'un oscillateur laser et d'un signal de son détecté représentatif d'un son se produisant lorsque la surface d'impression est brûlée par un rayon laser qui lui est appliqué.
