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 relevant parameters are shown with its…

Deinkability of different printed products
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. The Deinkability Score assessment defines categories of printed products with different target values…

Deinkability test methods
Newspapers and magazines in Europe are mainly based on papers manufactured from mechanical pulp and deinked pulp, so-called wood-containing papers. The most efficient deinking processes for these paper products are in an alkaline environment. Therefore, deinkability tests developed also assume alkaline deinking conditions. INGEDE was the first and only association which established a deinkability standard…
