Inkjet printing apparatus includes a print head for directing radiation curable ink onto a substrate and a curing device for directing radiation along a path toward ink received on the substrate. The apparatus includes a shield and a mechanism for selectively moving the shield into and out of the path of radiation. Control of movement of the shield enables the intensity of radiation received on the substrate to be varied to ensure that the substrate does not overheat during a curing operation.
La présente invention concerne un appareil d'impression à jet d'encre qui comprend une tête d'impression destinée à diriger une encre séchable par rayonnement sur un substrat et un dispositif de séchage destiné à diriger un rayonnement le long d'une trajectoire menant à l'encre reçue sur le substrat. L'appareil de l'invention comprend un blindage et un mécanisme qui permet de déplacer sélectivement le blindage dans la trajectoire du rayonnement et en-dehors de celle-ci. En régulant le mouvement du blindage, on peut varier l'intensité du rayonnement reçu sur le substrat de façon à éviter une surchauffe de ce dernier au cours d'une opération de séchage.
