Method for obtaining uniform porosity in printed inherently porous cigarette tipping papers

摘要

A method for obtaining uniform porosity in printed inherently porous cigarette tipping papers from base papers of differing relative porosities, comprising measuring the porosity of the base paper and adjusting the viscosity of the ink used to print the base paper relative to the porosity of the base paper. The viscosity of the ink is progressively increased or decreased relative to decreases or increases respectively in the porosity of the base paper to arrive at a predetermined uniform final porosity in the printed paper.
