BOUNDARY LAYER AIR SCRAPER FOR A ROTOGRAVURE PRINTING PRESS PATENT ABSTRACT A rotogravure printing press includes a boundary layer air scraper which is located immediately upstream of the pinch area of the press (e.g. the area formed by the impression roller and the printing cylinder). The air scraper blocks boundary layer airflow drawn with the moving web. This reduces the solvent laden air and allows a reduction in the capacity of the scavenger system.
