Abstract: A method and apparatus for a test pattern used in the alignment of an ink-jet pen which deposits fixer fluid, or other clear ink precursor fluid, or even colored ink fluid, on print media incorporates a colorless chemical marker in the fixer that is either infrared- or ultraviolet-sensitive and can either be observed using IR-sensitive detectors or visually, respectively, upon application of IR (or near-IR) radiation or UV radiation, respectively. Thus, data may be obtained with respect to deviations in a carriage-scan x-axis and a paper scan y-axis. Thus, the teachings of the present invention permit a determination of the extent of misdirected or missing nozzles.

Abstract: A class of magenta dye chromophores generally described as metal complexes with dye ligands of 4-hydroxy-3-(2'-pyridylazo)-1-(sulfo substituted) naphthalene for use in ink-jet inks is disclosed. The dye ligands are coordinated to a polyvalent metal. The dye-metal complexes of the present invention provide excellent ink-jet prints having excellent lightfastness when exposed to direct sun light as well as office light.

Abstract: The center-to-center spacing of pens containing a "problematic" combination of inks is increased to introduce a relatively small additional time-delay in which those particular constituents are applied to the same or adjacent areas during a single pass, thereby providing a substantial improvement in print qualities (such as Halo or Bleed) on plain (untreated) and special purpose (matt, glossy, transparent) print media, without substantially increasing the throughput rate. The center-to-center spacing of a critical combination of pens is substantially greater than the width of a single pen, thereby providing an increased delay that is equal to the increased spacing divided by the traverse speed.
