Abstract
A stack of planographic printing plates is accommodated in a packaging box for planographic printing plates in a manner such that imaging surfaces of the planographic printing plates are directed toward a bottom face plate. Therefore, when the packaging box for planographic printing plates is opened in a manner such that top face plates are directed upwards, the imaging surfaces of the planographic printing plates are directed downwards.

A planographic printing plate packaging product comprising:
- a stack of planographic printing plates that each includes one surface as an imaging surface;
- and
- a packaging box that accommodates the stack of planographic printing plates, the packaging box including an entrance for manually taking out the printing plates accommodated therein;
- and
- a plurality of sheets of cardboard at intervals of the printing plates for protecting the printing plates from damage or deformation due to an external force acting on the packaging box;
- wherein the planographic printing plates are accommodated and packaged in the packaging box in a manner such that the imaging surfaces of the planographic printing plates are directed to a side opposing the entrance, and at least one of the imaging surfaces include a recording layer having a solubility that changes with respect to a developer when the recording layer is irradiated with a laser beam;
