Abstract
Growth and clustering of halftone dots is a drawback in the reproduction of halftoned continuous tone images on prior art recording materials. Certain thermographic materials show a local microdot shrink effect called negative cross-talk upon neighboring microdots when exposing a microdot. Exposing these materials according to the frequency modulated halftone data of an image results in better tone rendering and lower noise due to lower dot clustering or negative cross-talk characteristics.
