This video, courtesy of Heidelberg, is included in the online companion to Introduction to Graphic Communication. Related videos and other interactive content are accessible on mobile devices using the free CP Clicker app from Ricoh. The video player provides ways to navigate more easily through longer videos and ask questions or add comments in the timeline (for logged-in users). Other interactive features, including in-video questions, are planned for early 2019. (Some video features are not yet available on smaller-screen iPhones.) Contact the publisher for more information.
