Jacket back designs span a larger area than any other common embroidery position. The fabric shifts during hooping in ways that left chest logos do not. Heavy underlay is required across the full design area, and the sequencing must prevent distortion as the design builds up layer by layer.
Most embroidery digitising services plan jacket backs the same way they plan small left chest logos. They just scale up the approach. This produces distorted results on the production floor.
At PlixaLabs, jacket back designs are mapped zone by zone, the shoulder area, the mid-panel, and the lower section each planned separately and sequenced together for a clean result across the full design.
