摘要： A printhead for an inkjet print cartridge capable of generating low drop weight ink drops is produced by reducing the dimensions of the firing chamber. A thinner orifice plate is needed to reliably achieve the lower drop weight ink drops. To overcome the material strength limitations of such a thinner orifice plate, an annealing step in the manufacture of the printhead is employed to modify the material properties of the orifice plate. This improved process improves the print quality of printers and aids in the production handling properties of the orifice plate. Orifice plates having a thickness in the range of 25 .mu.m to 40 .mu.m are being produced.

摘要： Islands of barrier layer material of an inkjet printhead are disposed between an ink source and the ink feed channels leading to the ink firing chambers to filter particles in the ink. Dimensions of the ink feed channels and ink ejecting orifices have been reduced in size and the thickness of the barrier layer has been made thinner. The nominal size of the filter pores is less than the barrier layer thickness while the width of the ink feed channels and the bore diameter of the orifices is larger than the barrier layer thickness.

摘要： Aqueous inks are provided for use in vehicles employing from about 10 to about 40 wt % of one or more organic solvents; and optionally up to about 5 wt % of an additive independently selected from the group consisting of surfactant, buffer, biocide, and mixtures thereof. The inks comprise, by weight, from about 1 to about 10 wt % Reactive Black 31 dye in either or both of its hydrolyzed forms, namely vinyl sulfone form and ethyl hydroxy form. Ink-jet inks made using the Pacified Reactive Black 31 provide improved lightfastness across a range of printing media while providing reliable ink-jet pen performance.
