摘要： The method and apparatus make a printing plate such as a lithographic printing plate by exposing an original plate of the printing plate such as a presensitized plate in a substantially oxygen-free state. The method and apparatus deprive substantially of oxygen at least an exposed area of the original plate being exposed to light at least during exposure and expose the original plate to the light at a wavelength of between 250 nm and 420 nm. The original plate has on a support an image recording layer containing a polymerization initiator, a polymerizable compound and a binder polymer, being sensitive to the light at the wavelengths of between 250 nm and 420 nm, having no oxygen barrier layer, and being removable with a printing ink and/or a fountain solution. That is, a latent image is formed by photo-polymerization on the original plate and the original plate is subjected to development on a printing press.

摘要翻译： 该方法和装置通过在基本上不含氧的状态下暴露印版的原版，例如未敏化的印版，从而形成诸如平版印刷版的印版。 该方法和装置至少在曝光期间至少暴露于原始板的曝光区域，使原始板暴露在250nm至420nm之间的波长的光下。 原版在载体上具有含有聚合引发剂，可聚合化合物和粘合剂聚合物的图像记录层，对波长在250nm和420nm之间的光敏感，不具有氧阻隔层，并且可以用 印刷油墨和/或润版液。 也就是说，在原版上通过光聚合形成潜像，并且在印刷机上对原版进行显影。
