Abstract: A method of providing a printhead assembly having a hydrophilic ink pathway and a hydrophobic ink ejection face. The method includes the steps of: providing a printhead assembly comprising a printhead attached to an ink supply manifold, the printhead comprising a nozzle plate having a hydrophobic coating and a protective metal film disposed on the hydrophobic coating; treating surfaces of an ink pathway in the printhead assembly with a solution comprising an alkoxylated polyethyleneimine; drying the surfaces; and removing the protective metal film so as to reveal the hydrophobic coating.

Abstract: A method for hydrophilizing surfaces of a printhead assembly includes decontaminating the printhead assembly; plasma activating the surfaces of the printhead assembly; treating the surfaces of the printhead assembly with a treatment solution; drying the printhead assembly; baking the printhead assembly; and performing a print quality and electrical test on the printhead assembly. The step of decontaminating the printhead assembly is performed before the step of plasma activating the surfaces of the printhead assembly.

Abstract: An apparatus (10) to aid in fixing dye to fabric having housing (15) having a portion (20) to receive and support a printer (25) to apply dye to the fabric (40) as it passes a predetermined location (50). A first set of rollers to provide for movement of the fabric (40) through the housing (15) so as to pass the location (50); a steamer (55) within the housing (15) and through which the fabric (40) passes after the location (50), the steamer (55) being adapted to aid in fixing the dye to the fabric (40); means (75) to deliver steam to the space; and wherein the apparatus (10) further includes: a second set of rollers to provide for the passage of the fabric (40) from the predetermined location (50) to the steamer (55).
