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, on print media uses the change in reflectivity caused by overprinting a series of positional-calibration indicia with colorant to obtain data with respect to deviations in a carriage-scan x-axis and a paper scan y-axis. Thus the invention measures distances between pens or nozzles.
