Abstract
In a method of packaging planographic printing plates disclosed herein, a stack is formed by planographic printing plates and interleaf sheets, or by only planographic printing plates. The stack is packaged with internal packaging paper without using conventional protective cardboard. In a packaging structure for planographic printing plates, the stack is loaded on a loading member and a top plate is placed on the stack. The stack and the loading member are integrally bound with a fixing band made of resin without using a conventional bolt-fastening operation. A reinforcing plate is fixed onto the top plate correspondingly to the fixing band so as to prevent bending or deformation of the top plate.
Claims20
A packaging structure for planographic printing plates in which planographic printing plates are packaged, comprising:
- a stack in which only a plurality of planographic printing plates, or a plurality of planographic printing plates and a plurality of interleaf sheets each protecting a coating film of the planographic printing plate are stacked in a thickness direction;
- and
- a packaging material for packaging the stack.
A method of packaging planographic printing plates in which a packaging structure for planographic printing plates, comprising a stack in which only a plurality of planographic printing plates, or a plurality of planographic printing plates and a plurality of interleaf sheets each protecting a coating film of the planographic printing plate are stacked in a thickness direction, and a packaging material for packaging the stack, is formed, said method comprising the steps of:
- stacking a plurality of planographic printing plates to form a stack;
- and
- packaging the stack formed by the stacking step with the packaging material.
A packaging structure for planographic printing plates, comprising:
- a planographic-printing-plate loading member on which a stack formed by stacking a plurality of planographic printing plates in a thickness direction can be loaded;
- an end plate which is disposed in contact with the stack at a side opposite to the planographic-printing-plate loading member;
- a binding member for binding the planographic-printing-plate loading member, the stack and the end plate in the state of being wound thereon;
- and
- a reinforcing member mounted on the end plate so as to be positioned between the end plate and the binding member, the reinforcing member being provided so as to alleviate pressure from the binding member and make the pressure to act on the end plate.
