Plate Processor question.

[UnlimitedBT]

Hi guys. Anyone can tell me please what is the difference between the Analog plates processor and CTP plate processor?
The reason why I am asking - we have two of JetPlate 64P Processors that's manufactured by FERPA GRAPHICS
It says: The JetPlate Processor 64 is designed to process the pre-sensitized, subtractive
aluminum offset plates imaged by the JetPlate system, as well as those
same plates conventionally imaged.
I have intend to sell them and they seem like really nice, microprocessor controlled units but I don't want to offer them where they're would be unappropriated for the job... I know thery were meant to work with Kodak Craftsman Plates and similar...
Thank you.
Roman.
