Document Type and Number:
WIPO Patent Application WO/2017/205604
Kind Code:
A8
Abstract:
Disclosed are a printer vacuum tables, and corresponding systems and methods for their use, in which the printer vacuum tables include multiple zones to apply vacuum, to hold a variety of media types and thicknesses within a given flatness range, to allow high definition printing. The vacuum zones run in the print direction, and each can be controlled for vacuum on and off. In an illustrative embodiment, the vacuum zones include one or more vacuum zones that are fixed with respect to a printer vacuum table surface, and one or more variable vacuum zones that are movable with respect to the printer vacuum table surface. One or more of the vacuum zones can be turned off if the print media does not cover the zone, such as to prevent leakage, and to provide more consistent vacuum hold down, regardless of media size or width.
