A vacuum surface for a wet - dye - printing device, and an ink jet printing apparatus with such a vacuum surface

摘要

Support plates surfaces structure (200; 300; 400) for a vacuum holding-down device (101) with a supporting plate (109) of a pressure device (100) for printing with wet - dye on printing media, wherein said printing means (100) a vacuum generator for producing a predetermined has be (fv), with the supporting plate (109) a first surface for receiving the print media to the same, the first surface having a predetermined width dimension along a predetermined first axis of symmetry, and wherein the first surface a plurality of vacuum ducts (203; 303; 403), which are arranged distributed parallel, wherein each of the vacuum ducts substantially parallel to the first axis of symmetry is, with adjacent vacuum channels essentially an identical, predetermined shape of the channel and predetermined channel dimensions have; each of the vacuum channels (203; 303; 403) at least one vacuum connection (205; 305; 405;), which is associated with it, each of the vacuum channels in each case with the vacuum generator are connected fluidically couples, wherein each of the vacuum channels of adjacent vacuum ducts by means of ribs (207, 307, 407) of the support plates is separated surfaces structure,..
