USED PRINT PLATE BUYING PRICE DETERMINATION METHOD AND DEVICE

摘要

A first planned buying price of a used print plate per unit collection amount, which is applied to a reusable used print plate, and a second planned buying price, which is lower than the first planned buying price and is applied to a non-reusable used print plate, are stored at a planned buying price memory device (72). A buying price calculation device (76) obtains a first buying price of a used print plate (33) in accordance with shipment data including a shipment amount of a print plate, collection data including a collection amount of used print plates, and the first planned price when the used print plate (33) is reusable as a raw material of an aluminum support member (11) of a print plate. The buying price calculation device obtains a second buying price of the used print plate (33) in accordance with the shipment data, the collection data and the second planned price when the used print plate is not reusable.
