Abstract
A vacuum table for a wide format printing system, wherein a medium support surface with vacuum holes therein is spaced apart from a bottom plate by a spacer array. The spacer array is formed by an integrally formed spacer structure with a first and a second longitudinal plate positioned between the bottom plate and the medium support surface. These plates comprise a plurality of air flow through-holes as well as a top support edge and a bottom support edge extending equidistantly to one another. A connection element connects the first longitudinal plates and is positioned between the bottom support plane and the top support plane. The use of longitudinal plates allows the spacer to be cheaply and easily produced by punching. The plates further offer the advantage of a low air flow resistance while maintaining a high rigidity of the spacer array.
