1. A method of inkjet printing comprising:
- imaging a substrate;
detecting variations in print parameters of an inkjet printing system;
calculating a correction factor based on the imaged substrate and detected variations in print parameters;
adjusting at least one print parameter of the inkjet printing system based on the correction factor;
determining an intended deposition location on the substrate; and
depositing an ink drop to the intended deposition location using the inkjet printing system after adjusting the at least one print parameter.

Abstract
Methods and apparatus for inkjet 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.
