The threads of a fabric that run horizontally across the width of the fabric, interweaving with the warp. The weft is commonly a fabric's direction of lesser strength. Also known as the woof. See also Warp.
Term for the direction in which an offset press blanket has the least strength, which should ideally be across its width, not in its around-the-cylinder direction. A press blanket has been prestretched during manufacture to compensate for any stretching that may occur when it is mounted around the blanket cylinder. A blanket with greater strength across its width will become baggy on press, and cause slurring of printed images. The direction of greatest strength is called its warp. See Blanket.
