EPRC deinkability assessment The deinkability assessment according to EPRC (European Paper Recycling Council) sets targets and limits for the evaluation of the deinkability of a print product and is based on the results of INGEDE Method 11.1 In total, five parameters have to be determined for the assessment of the deinkability (Figure 1). Three parameters
