Abstract
A document determination system includes a server apparatus that stores document data, a second multi-function printer that generates an authentic printed product, which is an authentic printed product in which a document represented by document data stored in the server apparatus is printed and in which at least a portion of the document is printed in composite black that is black represented using ink of a plurality of colors, and a third multi-function printer that reads a printed surface of a reading target including the authentic printed product and a duplicate of the authentic printed product. The server apparatus determines, based on whether at least the portion of the document represented by read data generated through reading by the third multi-function printer is printed in composite black, whether the reading target read by the third multi-function printer is the authentic printed product.
