The recently announced HP Pagewide XL printer delivers high quality output at very high printing speeds. The breakthrough speed of Pagewide XL is delivered via an array of nozzles covering the entire paper width (an order of magnitude more nozzles than traditional scanning systems). All the drops are fired in a single pass, which leads to a heightened sensitivity to nozzle errors for output quality, and to servicing drops for print production costs. Robust and reliable operation, along with economical print production are enabled by an inkset developed for this application. First, the Pagewide XL inkset uses pigment colorants that are quickly immobilized when contacting paper surface, leading to high color saturation and high black optical density at lower levels of ink coverage. The pigmented colorants, along with HP's polymeric binders also deliver better resistance to water, highlighters, and light fade. Second, the inkset has an additive that migrates to the ink/air interface in the nozzle. This film-forming additive produces a vapor barrier that slows water loss and enables extended uncapped periods while maintaining good drop ejection. Finally, the ink components work together to minimize the need for servicing spits to keep nozzles healthy, which improves uptime, productivity, and reduces print production costs.
