Estimation of Paper Printing Properties with Various Types of Fillers. — 2012. — № 3(37). — рр. 128–132.
    One of the main trends in manufacture of high-quality printing grades of paper is the increasing use of fillers which can provide cost and energy savings, improve paper properties and increase productivities. At the same time the increasing of filler content in a paper associates with some problems such as reducing paper strength and stiffness, increasing size demand, and others. In order to solve these problems different methods of filler modification have been proposed.
    In the Republic of Belarus at industrial enterprise of «Paper mill»Goznak the new technology of GCC fillers modifying by cationic starch have been introduced.
     In this work the complex estimation of paper printing properties with various types of cationic starch modified by GCC fillers is carried out. In order to determine the complex influence of filler type, it form, and content on paper printing properties, including ISO brightness, optical density of prints, printing contrast, and dot gain, the values of overall Harrington’s desirability D function is calculated. It is found that the maximum positive effect on paper printability (D = 0,80) is achieved by using the marble type of modified GCC filler.
