Collection method, collection system, recycling method and collection container for used printing plate

摘要

An IC tag (18a) is fixed to a printing plate (18). An ID code is stored in the IC tag. A used printing plate (33) is collected using a collection container (35). The collection container is provided with a reception device (40) of the collected used printing plates. The reception device is provided with an IC tag reader (42). An ID code of the used printing plate is read with the IC tag reader. According to the read ID code, whether to reuse the used printing plate for a substrate (14) of the printing plate is judged. The used printing plates judged to be reused are sent to an aluminum substrate recycling plant (60a) and recycled as raw materials for aluminum used in production of the substrates for the printing plates.
