JEF
Machine-readable embroidery format
Description
A proprietary embroidery file format developed by Janome to store stitch data and machine instructions for compatible hardware.
Detailed explanation
JEF (Janome Embroidery Format) functions as the native stitch data file for Janome embroidery machines. It encodes specific stitch coordinates, hoop information, and thread color changes required for the machine to execute a design. Embroiders must ensure digital patterns are converted to this specific format to guarantee compatibility and correct rendering on Janome models.
