Hand feel.

How the printed area feels against the rest of the garment: soft and moving with the fabric, or stiff, thick, and boardy. It is a complaint category of its own, separate from cracking, peeling, or a color miss, and a print can pass every other check and still come back. Too much ink laid down, an underbase heavier than it needs to be, or too much adhesive powder on a transfer are the usual causes.
