  • Publication number: 20060092207
    Abstract: The present invention provides methods and apparatus for controlling the quantity of fluid output (e.g., drop size) by individual nozzles of a print head to a very high precision at a frequency equal to the frequency at which fluid is normally dispensed. This is achieved by mapping fluid quantity control information into the data that represents the image to be printed. Data representative of an image is received and converted into pixel data. In at least one embodiment, the pixel data includes pixels represented by N bits, and the N bits may represent a drop size for the pixel and a union of the N bits may represent a nozzle status. A print head may be controlled based on the pixel data, and the print head may include nozzles that are each adapted to deposit at least one drop size quantity of a fluid on a substrate.

  • Publication number: 20060071957
    Abstract: The embodiments of the present invention describe an apparatus and a method of visualizing droplets dispensed from an inkjet printing system. A droplet visualization system is integrated with the inkjet printing system and is capable of measuring the sizes and the speeds of dispensed inkjet droplets and capturing the trajectories of the dispensed inkjet droplets. The measured information regarding the sizes, the speeds and trajectories of the droplets is feedback to the inkjet printing system to monitor and to control the dispense operation of the inkjet printing system. Due to this feedback control, the uniformities of the sizes, the speeds and the trajectories can be monitored and be improved.
