摘要:
A media print system includes a first print unit, a second print unit, at least one actuator configured to move the first unit and the second unit relative to one another and a controller configured to generate control signals. The at least one actuator positions the first unit and the second unit at the first and second positions, respectively, during a first longitudinal pass of a medium and positions the first unit at a third position during a second longitudinal pass of the medium in response to the control signals.

A media print system includes two or more printhead carriages adapted to print on a medium in a print area, the print area including two or more print regions. Each of the printhead carriages is adapted to print in one or more of the print regions. The system also includes a controller adapted to reconfigure a positioning of the two or more printhead carriages in a configuration selected from a predetermined set of configurations. The controller is adapted to reconfigure the positioning each time a predetermined criterion is satisfied.

A composition includes an alkenyl succinic anhydride sizing agent or an alkyl ketene dimer sizing agent. The alkenyl succinic anhydride sizing agent is present in an amount ranging from about 1.0 pounds per ton to about 4.0 pounds per ton. The alkyl ketene dimer sizing agent is present in an amount ranging from about 2.0 pounds per ton to about 10.0 pounds per ton. A metallic salt is also incorporated in the composition.

Systems and methods for providing smudge resistant and durable ink-jet images are provided. Specifically, a system for printing durable ink-jet ink images can comprise a first printhead containing a fixer composition including a charged fixer component, wherein the first printhead is configured for ink-jet printing the fixer composition on a substrate. The system can further comprise a second printhead containing an ink-jet ink, wherein the second printhead is configured for ink-jet printing the ink-jet ink composition over the fixer composition. The ink-jet ink can also include a colorant carrying an opposite charge with respect to the charged fixer component. A third printhead containing a polymer overcoat composition can also be present, and can be configured for ink-jet printing the polymer overcoat composition over ink-jet ink composition. The polymer of the polymer overcoat composition can also carry an opposite charge with respect to the charged fixer component.
