Essential Findings for Production Teams
When ordering digitized embroidery files, receiving the correct machine-specific format is essential for smooth production run-times.
1. Tajima (.DST) - The Universal Commercial Standard The Tajima .DST file is accepted by virtually all industrial embroidery equipment (Tajima, Barudan, SWF, Happy, Ricoma, ZSK). It stores precise needle coordinates, jump stitches, and stop commands.
2. Brother & Baby Lock (.PES) Used extensively by home and semi-professional single-head or 6-needle Brother embroidery machines. PES files store color palette information directly in the file header.
3. Melco & Bernina (.EXP) Standard format required by Melco EMT16X multi-head commercial systems and high-end Bernina embroidery machines.
4. Janome (.JEF) & Husqvarna (.HUS) Format extensions standard across Janome Memory Craft systems and Husqvarna Viking home embroiderers.
At Power Digitizing, every client receives the master Tajima DST file along with any specific format required for their embroidery setup.
