About BMP files
BMP is the uncompressed Windows bitmap format. BMP files are completely uncompressed, so there are zero compression artifacts — every pixel is exactly as authored. BMP has no transparency, so the automatic background removal detects and strips solid backgrounds instead.
Tip: Keep the background a single flat colour so the automatic background removal can strip it cleanly.
About the EXP format
EXP (Melco Expanded format) is read by Bernina home machines and Melco commercial embroidery machines. The format stores raw stitch data with no thread-colour table. Load via USB. EXP carries stitches and colour stops only, so you set the actual thread colours on the machine.
