Differentiation by printing technology 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
