Web guiding structure with continuous smooth recesses

A web-guiding system for guiding a web of media having a width spanning a cross-track direction travelling from upstream to downstream along a transport path in an in-track direction, the web of media having a first side and an opposing second side, comprising:

• a web-guiding structure including an exterior surface having a pattern of alternating ridges and recesses formed into the exterior surface, wherein the web of media travels past the web-guiding structure with the first side of the web of media contacting at least some of the ridges on the exterior surface of the web-guiding structure;
• wherein the ridges and recesses are formed into the exterior surface of the web-guiding structure such that the exterior surface has a continuous and smooth surface profile in the cross-track direction, the surface profile having a maximum slope magnitude of no more than 0.3 and a minimum radius of curvature magnitude of no less than 5 mm.
