Abstract:
A method for imaging on a thermographic material, the method comprising:(a) providing a layer of thermographic material;(b) scanning a beam along a line on a surface of the thermographic material in a first direction, the beam comprising images of a plurality of light sources, the images all lying on the line;(c) providing data representing an exposure to be given to a spot lying on the line;(d) modulating each of the light sources in response to the data in a manner synchronized with scanning the beam along the line such that:(i) a first one of the light sources is modulated in response to the data during a dwell time when an image of the first one of the light sources is on the spot; and,(ii) each subsequent one of the light sources is modulated in response to the data during dwell times when an image of each subsequent one of the light sources is on the spot.
