Title (EN) DRYING SPEED ADJUSTMENTS VIA DENSITY INDEX ANALYSIS
(FR) AJUSTEMENTS DE VITESSE DE SÉCHAGE PAR ANALYSE D'INDICE DE DENSITÉ
Abstract:
(EN) An example of a print system including a dryer to dry a sheet of paper. The print system includes a media feeder to feed the sheet of paper into the dryer and a controller to vary a speed of the media feeder. The print system includes a communication interface to receive data associated with an image to print on the sheet of paper and a processor. The processor is coupled to the controller and the communication interface. The processor is to determine a first density index for a first portion of the image and to determine a second density index for a second portion of the image. The processor is to adjust the speed of the media feeder via the controller based on the first density index and the second density index.
(FR) Selon la présente invention, un exemple d'un système d'impression comprend un séchoir pour sécher une feuille de papier. Le système d'impression comprend un dispositif d'alimentation de support pour alimenter la feuille de papier dans le séchoir et un dispositif de commande pour faire varier une vitesse du dispositif d'alimentation de support. Le système d'impression comprend une interface de communication pour recevoir des données associées à une image à imprimer sur la feuille de papier et un processeur. Le processeur est couplé au dispositif de commande et à l'interface de communication. Le processeur doit déterminer un premier indice de densité pour une première partie de l'image et déterminer un second indice de densité pour une seconde partie de l'image. Le processeur doit ajuster la vitesse du dispositif d'alimentation du support par l'intermédiaire du dispositif de commande en fonction du premier indice de densité et du second indice de densité.
