EFI™ senior applications specialist, Brian Bernard, offers some tips and tricks on roll-to-roll, double sided printing on VUTEk® hybrid printers. While this application is not entirely supported, it is doable provided it is done carefully and close attention is paid to setup and placement of the image. Perfect back to front registra-tion should never be expected, however, as that can only be achieved using the media fence in sheet mode. The following tips are for a banner application as opposed to a backlit application.
