Lengthwise threads in a woven fabric, and typically the fabric's direction of greater strength. See also Weft.
Term for the direction in which an offset press blanket has the greatest strength, which should ideally be in the direction of its length, or 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 least strength is called its weft. See Blanket.
In video production, the term warp refers to a digital video effect used as a transition between scenes in which the incoming image is rotated and enlarged to cover the outgoing image. Alternately, the outgoing image may be rotated and reduced to reveal the incoming image.
