Zusammenfassung:An improved photopolymer coversheet film including no microindentations or micropitting is disclosed. One embodiment of the process for forming the improved the photopolymer coversheet film includes a modified casting (casting and coating) method. This embodiment exhibits no microindentations or micropitting in its smooth surface. Another embodiment of the process for producing the improved photopolymer coversheet film includes the use of a reheat embossing step to achieve no surface microindentations greater than 0.5 microns in depth.
