polymerization offset negative type CTP plate, applied using 405nm violet laser diodes as a light source CTP platesetter.
applicableto the newspaper, books andpackaging printing, which is applicable to the resolution of the outputdevice to 100-150lpi 1000-2400dpi plusnetwork files when using 1800-2540dpi equipment 175lpi or higher resolution outputplus net accuracy when a file that can be used for commercial printing. But the need to find appropriate parameters and optimum machine and plate matching when using the machine, otherwise themachine, dot 10% or less have lost points on the plate phenomenon, 30% -70% of the networkhas reduced the phenomenon. Therefore not recommended for high-resolution outputfile.
