A scientific evaluation of the factors influencing deinkability has to consider the printing technology and the printing conditions. The results of the deinkability survey in Figure 1 give a general average overview. Detailed technical data of the printing process are not always available. In this average documentation of deinkability results, all relevant parameters are shown with its…

The deinkability of conventionally printed products depends largely on the printing technology and on the type of ink applied on the paper substrate, but sometimes also the paper itself (coated or uncoated), and the age of the printed product at the time of deinking.
