The smooth surface makes it possible to utilize the printing plate precursor in preparing planography plate with long running period.
这种光滑的表面使得能够由所述版前体制备在印刷过程中具有高的运转周期的平版印刷版。
When the planography heat-variable negative recording imaging element is coated on the proper substrate, it is able to form the planography printing plate precursor which is not treated.
当该平版热敏阴图记录成像元件被涂布在适当的基版上能够形成无处理平版印刷版前体。
The purpose of the invention is to provide a heat-variable negative recording imaging element and non-treatment planography printing plate precursor.
