Quality of the garment. When selecting embroidery over silk-screen, the garment is always of higher quality then a garment selected for silk screen. When applying embroidery to a garment, the computerized embroidery will outlast the garment many times over. The normal density of the embroidery is from 2x to 6x times what the garment is made from. Most shirt backs embroider best if they are from a woven material.
Knitted material has a tendency to contract or pucker causing distorted embroidery.
