Design Scaling and Sett Adjustment for Production
topic
Jacquard design scaling adjusts the pixel dimensions of the design bitmap to match the actual thread count per centimetre in the woven fabric, with the design width in pixels equal to warp ends per centimetre multiplied by design repeat width in centimetres, and the design height in pixels equal to picks per centimetre multiplied by repeat height, with the warp-to-weft pixel aspect ratio matching the thread ratio that determines whether the woven design is geometrically proportional to the original artwork or requires pre-distortion to compensate for anisotropic thread spacing.
Role
Ensures that the woven fabric reproduces the intended proportions of the original design by correctly matching the pixel grid of the design programme to the physical thread grid of the woven fabric, with scaling error being the most common cause of distorted design proportions in woven Jacquard fabrics where incorrect aspect ratio compensation produces circles appearing as ellipses and squares as rectangles in the finished cloth.
