Design Repeat and Harness Neck Planning
topic
Design repeat planning determines how the Jacquard design image is distributed across the fabric width in relation to the machine hook capacity, with unrepeated designs using single-end harness control assigning each warp end to a unique hook for full-width non-repeating imagery, half-drop and mirror repeats using grouped neck configurations that share hook control across multiple design repeats across the width, and the total design width in hooks determined by warp sett multiplied by repeat width in centimetres.
Role
Establishes the fundamental relationship between design size, hook capacity, and fabric width that determines whether a given design can be woven on available Jacquard equipment, with harness neck planning being the technical assessment step that determines the minimum hook capacity required for each design and the appropriate neck configuration for each combination of design width, warp sett, and machine capacity that the weaving production requires.
