Abstract
The present invention provides a method for printing and coating a flexible substrate web so as to attain a specified coefficient of friction on both sides of the substrate web which employs the use of controlled set-off of coated and/or printed material from the front side to the back side side of the web. Furthermore the method provides a substrate web produced therefrom and the method is useful for packaging substrate webs and, in particular, foil substrate webs.
