Abstract
(EN)
A printhead replacement liquid for active light hardening inkjet printer that prevents any nozzle clogging of the printhead thereof; and a method of cleaning a printhead of active light hardening inkjet printer with the use of the printhead replacement liquid. The printhead replacement liquid for active light hardening inkjet printer is one for use at the time of filling with an ink the ink unfilled printhead of active light hardening inkjet printer or at the time of refilling the ink filled printhead with another ink, characterized in that the printhead replacement liquid contains not only 10 to 40 mass% of at least one cyclic ester compound but also 10 to 40 mass% of at least one polymeric compound contained in newly charged ink.

La présente invention concerne un liquide de remplacement pour tête d'impression pour imprimante à jet d'encre durcissant à la lumière active qui empêche tout encrassement des buses de la tête d'impression connexe ; et un procédé de nettoyage d'une tête d'impression d'imprimante à jet d'encre durcissant à la lumière active par l'utilisation du liquide de remplacement pour tête d'impression. Le liquide de remplacement pour tête d'impression pour imprimante à jet d'encre durcissant à la lumière active est destiné à l'utilisation au moment de remplir avec une encre la tête d'impression non remplie d'encre d'imprimante à jet d'encre durcissant à la lumière active ou au moment de remplir à nouveau la tête d'impression remplie d'encre avec une autre encre, qui se caractérise par le fait que le liquide de remplacement pour tête d'impression contient non seulement de 10 à 40 % en masse d'au moins un composé d'ester cyclique mais aussi de 10 à 40 % en masse d'au moins un composé polymérique contenu dans l'encre nouvellement chargée.
