Selecting the embroidery file format

In order that embroidery motifs can be read by the BERNINA embroidery machine, they have to be created
by the BERNINA Embroidery software and exported as .EXP file. Besides the actual embroidery file, a .BMP
file and an .INF file are generated additionally. The .BMP file allows a preview of the embroidery motif and
the .INF file provides the information on the thread colors. Please note: If the .INF file is missing, the
embroidery motif cannot be displayed in the real color but only in standard colors. In this case, the colors can
be entered manually in the color overview of the motif on the machine.
Additionally, following embroidery formats can be read by the machine: .PES, .PEC, .XXX, .PCS, .JEF
and .DST. BERNINA International AG doesn't warrant that embroidery motifs which have not been created or
converted by the BERNINA Embroidery software can be correctly read and embroidered.
Simple motifs with a low stitch count are suitable for embroidery on fine material. Densely embroidered
motifs, e. g. embroidered motifs with multiple color and embroidery direction changes, are suitable for
medium and heavy-weight material.
