Abstract (en)

A method is disclosed for the formation of a heat mode image strongly improved for pinhole defect. A thermal imaging medium contains, apart from its image forming layer and several auxiliary layers, also a reducible organic metal salt layer, preferably a silver behenate layer. After information-wise laser exposure, lamination of a stripping sheet and delamination a negative heat mode is obtained. By means of an overall post-exposure of this image the pinholes in full recorded areas disappear due to reduction of the metal salt. In an alternative embodiment the metal salt layer is not present in the original thermal imaging medium but applied as part of a separate laminate on top of the processed negative heat mode image.
