Abstract
A test method for analyzing an OCC fiber pulp, to quantify the content therein of contaminants creating bleed-throughs in a paper product formed from the pulp. A sample of the pulp is formed into a sheet, and bleed-throughs are created from the contaminants therein by hot-pressing the sheet. A dye is applied to the sheet, to enhance contrast between areas of the sheet having bleed-throughs and areas of the sheet not having bleed-throughs. The contrasted sheet is analyzed to determine the quantity of contaminants that create bleed-throughs.
