If your stamped image isn't completely stamped, simply take a marker and connect the lines.

If you stamp a bolder stamp and you end up with a larger area that didn't stamp well, simply take a cotton swab and tap it on your inkpad and dab onto the area to fill it in. By dabbing, you feather the color in and get almost a seamless correction.
