ABSTRACT:
To correct for blooming artifacts in an ionographic imaging device, a summation of the effects of previously deposited charge is made prior to depositing ions to form the image, to determine the likely amount of displacement of any ion due to a previously deposited charge. A comparison of the displaced pixel position, with the desired image is made to determine where the ions will fall. If the ions are predicted to fall within an area in which ion deposition is desired, ions are allowed to pass to the imaging surface. If the comparison of the displaced pixel position with the desired image is made and predicts that ions will fall outside of an area in which charge is desired, ions are prevented from passing to the image surface.
