To provide a packing material which prevents as much as possible the occurrence of trouble caused by the difference in the type of interleaving paper used and which exposure processes on the most suitable device condition according to a printing plate and interleaving paper used.
A bar code 22 is placed on the side face of a packing box 10. The bar code 22 is recorded with the outer shape information and the physicality of a PS panel 12 and an interleaving paper 14. Therefore by reading the information recorded in the bar code 22 by a bar code reader in exposure processing, trouble caused by the difference in the type of PS panel 12 and the interleaving paper 14 is prevented, and exposure processing on the best device condition is performed.
