Claim 0:
1. A method for mitigating thermal ghosting on a printed image with an ink-based image forming device having a rotatable imaging member with a reimageable surface in an environment having an ambient temperature, the method comprising:
a) after an imaging of a prior image on the reimageable surface, measuring temperatures of the reimageable surface with a temperature sensor adjacent the reimageable surface, the temperatures being affected by stress induced by the imaging;
b) aligning information of a current image with a temperature map of the reimageable surface where the current image will be rendered, the information including a pixel-wise gray level of the current image, the temperature map associated with the measured temperatures by the temperature sensor;
c) determining a corrected current image including a gray level modification of the current image based on the pixel-wise gray level of the current image and the temperature map to decrease marking material density at reimageable surface discrete coordinates that are warmer than a reference temperature and prevent ghosting of the prior image on a printing of the current image; and
d) rendering the corrected current image on the reimageable surface for a printing by the ink-based image forming device, the printing of the rendered corrected current image appearing not as the corrected current image, but as the current image.
