Patent number: 8926049Abstract: In a method to execute a pause in an ink printing system printing operation in which a printing substrate web is printed with print bars having print heads, with aid of a take-up roller moving the printing substrate web at printing speed past the print bars in a transfer printing zone in order to generate print images. Upon triggering the pause, a strain state of the printing substrate web is measured at a beginning of the pause and stored as a desired strain state. During the pause, the strain state of the printing substrate web is measured as a real strain state at selectable points in time, and the real strain state is compared with desired strain state. Given a deviation of the real strain state from the desired strain state, at the selectable points in time the take-up roller is controlled so that the strain state of the printing substrate web assumes the desired strain state at the beginning of the pause.Type: GrantFiled: July 23, 2013Date of Patent: January 6, 2015Assignee: Océ Printing Systems GmbHInventors: Mehrad Biglari, Admir Lela, Peter Thiemann, Stephan Pilsl

Patent number: 8702228Abstract: Inkjet printing systems are provided that use a cross-module airflow to limit condensation between a printing module and a receiver and that supply a co-linear flow of air that flows along with ink droplets toward a receiver. An integration area is created between the inkjet printhead heads, the receiver and a barrier to allow co-linear flow and cross-module flow to integrate and flow from between the printing module and the receiver without disrupting travel paths of the ink droplets.Type: GrantFiled: December 20, 2012Date of Patent: April 22, 2014Assignee: Eastman Kodak CompanyInventors: Michael Joseph Piatt, David F. Tunmore, Timothy John Hawryschuk, Harsha S. Bulathsinghalage
