1. A system for use in inkjet printing comprising:
- a calibration substrate having at least one calibration mark thereon;
at least one inkjet print head adapted to deposit ink on the calibration substrate; and
a controller adapted to;
control deposition of the ink on the calibration substrate using the at least one inkjet print head,detect a deposited location of the deposited ink on the calibration substrate,compare the deposited location to an intend location, the intended location being indicated by the at least one calibration mark,determine a difference between the deposited location and the intended location, andcompensate for the difference between the deposited location and the intended location by adjusting a parameter of an inkjet printing system.

Abstract
Methods and apparatus for inkjet drop positioning are provided. A first method includes determining an intended deposition location of an ink drop on a substrate, depositing the ink drop on the substrate using an inkjet printing system, detecting a deposited location of the deposited ink drop on the substrate, comparing the deposited location to the intended location, determining a difference between the deposited location and the intended location, and compensating for the difference between the deposited location and the intended location by adjusting a parameter of an inkjet printing system. Numerous other aspects are provided.
