Abstract

Système de mélange d'encre, appareil d'impression à jet d'encre numérique à grande vitesse l'utilisant, et procédé d'impression à jet d'encre numérique à grande vitesse l'utilisant, l'appareil comprenant : une unité d'alimentation en matériau pour apporter un matériau à imprimer ; une unité d'impression de surface avant positionnée au-dessus de la surface avant du matériau à imprimer, et pour imprimer, au moyen d'une impression à jet d'encre, la surface avant du matériau à imprimer, qui est transféré au moyen de l'unité d'alimentation en matériau, au moyen d'un système de mélange d'encre ; une unité d'impression de surface arrière positionnée sous la surface arrière du matériau à imprimer, et pour imprimer, au moyen d'une impression à jet d'encre, la surface arrière du matériau à imprimer au moyen du système de mélange d'encre ; et une unité de séchage pour sécher le matériau imprimé qui a été imprimé au moyen de l'unité d'impression de surface avant et de l'unité d'impression de surface arrière. Le système de mélange d'encre comprend : une pluralité de sources pour apporter une pluralité de matériaux liquides comprenant une encre d'au moins une couleur ; une unité de mélange d'encre pour recevoir l'apport de la pluralité de matériaux liquides provenant de la pluralité de sources et mélanger les matériaux liquides reçus ; et une tête d'impression qui possède une pluralité de buses pour recevoir les matériaux liquides de l'unité de mélange d'encre et les pulvériser sur un objet. Par conséquent, la présente invention présente une structure compacte et occupe ainsi un espace minimal. En outre, la présente invention réduit au minimum les erreurs de couleur et permet des tests de couleur rapides et divers au moyen du mélange numérique d'encres. Et la présente invention ne génère pas de déchets de colorants et permet ainsi une réduction de pollution de l'eau et de la pollution de l'air.
