The PES file
Brother · Babylock
Getting it onto the machine
USB stick, root folder. Models: PE800, SE700, Luminaire.
How the file is built
A PES file has a PEC file inside it. PEC holds the stitches, the threads and the thumbnail; PES is the wrapper around it. Our writer builds the PEC first and wraps it, because that is the part the machine actually reads.
Colours
Brother machines know 64 fixed thread numbers. Every colour is matched to the nearest of those, so the shade on screen is the shade the machine will name — not a new one.
If your machine is not listed
Use DST. Every commercial machine reads it, and most home machines will too — it is the format the trade falls back on. The stitches are identical in all seven; only the wrapper differs, so «which format?» is a question about your machine and never about quality.
