The uniformity of a printer toner particle affects the distribution of charge the particle holds and as a result can affect image quality of the printed materials.
Image characterization can be used to determine shape, size, circularity and material uniformity of printer toner particles during and after production. In the application note we demonstrate that the FlowCam can be used for rapid quality control characterization of printer toner.
