Abstract
A method of producing a radiation-induced colorant transfer image on a support, includes the steps of: providing an image-receiving element comprising a support having thereon an image-receiving layer; providing a colorant donor element having a colorant transfer layer on a colorant element support and wherein colorant can be transferred from a transfer surface of the colorant donor element to the image-receiving layer in response to selectively applied radiation; providing a rigid element being configured to provide a surface having peaks and valleys; pressing either the colorant element support surface or the image-receiving support surface against the rigid element so as to cause either the colorant transfer layer surface or the image-receiving surface, respectively, to conformally have peaks and valleys; causing the peaks of the colorant transfer layer or the image-receiving layer to engage either the image-receiving element or the colorant donor element, respectively; and applying radiation to the colorant element support to cause colorant to transfer in the space between the image-receiving element and the colorant transfer layer surface corresponding to the valleys in the co…
