ABSTRACT:
A method for treating an imaging sheet is disclosed. The method includes the steps of providing an imaging sheet having coated on one of its surfaces a layer of microcapsules, the microcapsules containing a radiation curable composition and having an image-forming agent associated therewith, heating the sheet; and image-wise exposing the layer of microcapsules to actinic radiation; wherein the heating step is performed prior to or after the image-wise exposing step. The method reduces or removes damage defects on the imaging sheet and, in some instances, extends the dynamic range of the image-forming agents.
