Kurzbeschreibung (Abstract)
The INGEDE No. 11 test method for evaluating deinkability was introduced in 2001. It replaced the deinkability index based on brightness measurements used in earlier tests with an ink elimination (IE) index obtained by measuring effective residual ink concentration (ERIC) using Kubelka-Munk scattering and absorption coefficients. Following discussions at the European Recovered Paper Council in 2006, INGEDE developed a scoring system covering a range of properties for different printed products rather than print processes. Recent studies by Darmstadt Technical University's Department of Paper Production and Process Technology (PMV) have shown the need for modifications to the INGEDE 11 deinkability test method to evaluate newsprint derived from different fibres to ensure defibration occurs at a minimum pH level. The studies showed that deinking acceptability levels for different newsprints and for inkjet printed papers varied with changes in pH. The findings indicate that deinkabili ty should be determined by laboratory tests using different sodium hydroxide levels, even though this will involve more effort and a larger number of print samples.
