Keeping in mind that many people outsource the design components of their embroidery files and add lettering in house, I wanted to make some comment on the benefits of including editing to your embroidery software even if you outsource your digitizing.
We have all seen the variation in a stitch out depending on the fabric the design has been stitched to.
A common problem is if a design digitized for drill fabric is then stitched on a knitted garment or other stretch material, often there will be registration problems where adjoining segments do not align correctly.
This can be fixed easily by a simple realignment of the shaping nodes or even changing the stitch angle of one or both of the objects.
Neither remedy is complicated and does not require an in depth knowledge of digitizing.
