Retyne before the fabric goes in a quilt. Synthrapol for suspending dye in the water after construction. Throw in several colour catchers as well. Do not dry the quilt top until all bleeds are gone.
I think if is a bad bleeder, I would remove the border and use another fabric. I don't machine embroider but I think it would be best before the quilt it washed because the fabric is firmer with the sizing in it. I don't think I would want to wash the embroidery before the quilt top was quilted due to shrinkage.
