EPRC assessment on removability of adhesive applications in graphic paper products The assessment of the removability of adhesive applications from graphic paper products is in principle adopted to the assessment of the deinkability score. For an assessment method under laboratory conditions not only the screening but also the pulping process has to be defined because
