Publication number: 20190146384Abstract: In an example, a method of wetting a print blanket includes receiving a null cycle trigger during a printing session. The method also includes maintaining printing voltages on a forecast BID (binary ink developer) that has been prepared to print a next color separation onto a photoreceptor, and applying wet null voltages to a non-forecast BID. The method then includes engaging the non-forecast BID with the photoreceptor to transfer fluid other than ink to the photoreceptor during the null cycle.Type: ApplicationFiled: January 13, 2019Publication date: May 16, 2019Inventors: Vitaly Portnoy, Michel Assenheimer, Amiran Lavon, Eric G.
