ABSTRACT:
The present invention provides inkjet print nozzle calibration systems and methods for calibrating an inkjet print nozzle. The systems may include an inkjet print nozzle adapted to dispense ink onto a substrate in response to a firing pulse voltage, a light source adapted to illuminate the dispensed ink, an imaging system adapted to measure a transmittance of light through the dispensed ink, and a controller adapted to controllably adjust the inkjet print nozzle based on the measured light transmittance. The methods may include dispensing ink onto a surface with an inkjet print nozzle set at a firing pulse voltage, measuring a light transmittance characteristic of the dispensed ink, determining a volume of ink dispensed based on the transmittance characteristic, and adjusting a fire pulse voltage of the inkjet print nozzle based on a difference between the determined volume of ink dispensed and an expected volume level of ink dispensed.
