Use Prepare Artwork for Embroidery to prepare images for automatic digitizing. This automatically flattens colors, sharpens outlines, and reduces ‘noise’.
Reduce colors to a specified number
Reduce each block to a single color
Remove anti-aliasing, noise and dithering
Sharpen outlines.
Note: Processing makes it easier for the software to recognize distinct areas in the artwork. These areas then become the embroidery objects of the finished design.
