About PNG files
PNG is a lossless image format with full transparency support. A transparent PNG background is detected automatically, so your design's edges come out clean without any manual background removal. Lossless compression means no edge artifacts — colour regions trace exactly as drawn.
Tip: Export logos and clip-art as PNG with a transparent background for the cleanest stitch regions.
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.
