Abstract
(EN)
A device for controlling the inkjet printing position and the method thereof are disclosed. The method includes the following steps: detecting a color scale in a fed paper and outputting a pulse signal correspondingly by a color scale sensor (S10); setting an expected window in which the pulse signal takes place; when the pulse signal is detected in the expected window(S20), starting the inkjet printing after delaying a preset period, and when the pulse signal is not detected in the expected window or is detected out of the expected window, starting the inkjet printing after carrying out a correction (S30). The method improves the inkjet printing quality.

L'invention concerne un dispositif servant à commander la position d'impression par jet d'encre ainsi qu'un procédé associé. Le procédé comporte les étapes suivantes : détecter une gamme de couleurs sur un papier introduit et faire émettre en conséquence un signal impulsionnel par un capteur de gamme de couleurs (S10) ; spécifier une fenêtre prévue où intervient le signal impulsionnel ; lorsque le signal impulsionnel est détecté dans la fenêtre prévue (S20), entamer l'impression par jet d'encre après un retard d'une durée prédéfinie et, lorsque le signal impulsionnel n'est pas détecté dans la fenêtre prévue ou est détecté en dehors de la fenêtre prévue, entamer l'impression par jet d'encre après avoir réalisé une correction (S30). Le procédé améliore la qualité d'impression par jet d'encre.
