A Study on the Prevention of Print Mottle by Means of the Liquid Absorptivity Controlling in Coated Paper

Development of the paper coating technologies to prevent print mottle is needed to obtain high quality printing. Printing mottle is recognized as the most common printing problems in using coated paper and which is one of the most difficult problems to solve in offset printing. Print mottle is one of the most important quality properties of printed products and manufacturers strive to improve the paper surface to gain higher and more even print mottle. The prevention of printed mottle requires of coating color formation, especially the minimum of binder migration. The results the uniformity of liquid absorption by paper at very short contact time between paper and testing printing liquids.
