What is a JEF file?
JEF is Janome’s embroidery format, the file Janome’s machines read, the 7-needle MB-7 among them. It keeps Janome’s own colour number for each thread with the needle points, jumps and colour changes. Qepe writes it for Janome machines and reads every file back before it is saved.
- Qepe’s Janome profile follows the MB-7: 7 needles and three hoops, M1 24 × 20 cm, M2 12.6 × 11 cm and M3 5 × 5 cm, each with the field Janome publishes.
- SEW, Janome’s older format, opens in Qepe; JEF is what it writes.
How to make a JEF file from a logo
Open the logo
PNG, JPEG, WebP, SVG, PDF or AI. Qepe grades the file first: Good file, OK file or Poor file, with the reason.
Pick the machine
Choose Janome in the machine chip, and Qepe uses its needles and hoops. JEF is the machine’s own file there, or one click away under Export.
Set the size, garment and colours
Left chest, cap front, sleeve, full back or your own size in millimetres; ten garments, each with its own underlay, density and pull compensation.
Digitize and check
The Auto Digitizer makes the stitches. Quality scores them against the artwork out of 100, and Fix all corrects what is safe to correct.
Export JEF
Qepe writes the file, reads it back and compares every needle point with the screen. A file that doesn’t match is never saved, and the old one stays.
Convert PES to JEF
Open the PES file, or one in any of the 40 formats Qepe opens: it opens stitched as the file has it, to recolour, move or add a name to. Export writes the JEF and checks it like any other file. A machine file has no shapes to stitch again, so resizing it by more than 10 % changes its density: for a new size, digitize from the logo.
What Qepe compares before a JEF is saved
- Every needle point, each within 0.06 mm of the screen
- Every thread change and needle
- Every trim and stop
- The header the machine reads: stitch count, colours, extents and label
- The thread names, where the format keeps them
Questions
- What is a JEF file?
- Janome’s embroidery format: the needle points, jumps and colour changes, with Janome’s colour number for each thread. Janome machines read it.
- How large can a JEF design be?
- Qepe notes when a design passes JEF’s 200 × 200 mm limit, so you know before the machine does.
- Can I convert a PES to JEF?
- Yes. Open the PES in Qepe: it opens stitched as the file has it. Export JEF, and Qepe writes it and reads it back.
