    • A process of forming a halftone color proof containing at least one dye transfer image and at least one pigment transfer image, comprising imagewise-exposing, for less than about 10−4 sec., by means of a laser having a power density of greater than 104 W/cm2, a dye-donor element comprising a support having thereon a dye layer comprising a dye dispersed in a polymeric binder, the dye layer having an infrared-absorbing material associated therewith, the laser exposure taking place through the side of the support of the dye-donor element which does not have the dye layer thereon, and transferring a portion of the dye in the dye layer to a receiving element having thereon an image-receiving layer; and imagewise-exposing, for less than about 10−4 sec., by means of the laser, an ablative or propulsive pigment-donor element comprising a support having thereon a transfer layer comprising a pigment dispersed in a binder, the transfer layer having an infrared-absorbing material associated therewith, the laser exposure taking place through the side of the support of the pigment-donor element which does not have the transfer layer thereon, and transferring a pigment image to the receiving element to obtain the halftone color proof.
    • 一种形成含有至少一种染料转移图像和至少一种颜料转移图像的半色调色彩检验的方法,包括通过功率密度大于约10-4秒的激光成像曝光小于约10-4秒。 104W / cm 2,染料供体元件包括其上具有染料层的载体,染料层包含分散在聚合物粘合剂中的染料,染料层具有与其相关的红外线吸收材料,激光曝光通过支持体 的染料供体元件,并且将染料层中的一部分染料转移到具有图像接收层的接收元件上; 以及通过激光成像曝光小于约10-4秒的烧蚀或推进颜料施主元件,其包括其上具有分散在粘合剂中的颜料的转印层的载体,所述转印层具有 与其相关联的红外线吸收材料,激光曝光通过在其上没有转印层的颜料给体元件的支撑体的侧面进行,并将颜料图像转印到接收元件以获得半色调色彩。
