Title
(EN) INKJET PRINTHEADS
(FR) TETES D'IMPRESSION A JET D'ENCRE
Abstract
(EN)
Where material is to be removed from an element (4) of an inkjet printhead having a surface (6) intended to form part of the external surface of the printhead, at least part of the material being removed by ablation using a high energy beam directed at said surface, a protective layer (10) is applied to be in sealing engagement with the surface. The layer is believed to protect the surface from high energy free radicals liberated during the ablation process.
(FR)
Lorsque l'on doit enlever un matériau d'un élément (4) d'une tête d'impression à jet d'encre possédant une surface (6) conçue pour faire partie d'une surface externe de cette tête, une partie au moins de ce matériau étant enlevée par ablation à l'aide d'un faisceau à haute énergie dirigé sur cette surface, on applique une couche (10) protectrice qui doit être en contact d'étanchéité avec ladite surface. On pense que cette couche protège la surface des radicaux libres à haute énergie libérés lors du processus d'ablation.
