A forming fabric having a paper side layer and a machine side layer comprises at least two systems of weft yarns and warp yarns including both non-binding yarns and triplet sets of warp binder yarns. In the fabric weave pattern, each member of each triplet set of warp yarns interweaves with the paper side weft yarns to occupy in sequence segments of an unbroken warp path in the paper side surface, and the members of each triplet interlace in pairs with single machine side layer weft yarns. Each segment in the unbroken warp path is separated by at least one paper side layer weft yarn. Each triplet set is separated from the adjacent triplet sets by at least one non-binding warp yarn. In a modification of this forming fabric, the weft yarns also include paired binding weft yarns, the pairs being separated from adjacent pairs by at least one non-binding weft yarn. The machine side layer interlacing points can be regularly or irregularly spaced. Paper products made using these fabrics have enhanced printability.
