US 7,611,217 B2 · Methods and systems for inkjet drop positioning

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.

Dependent claims

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.
