Tattooing is to inject pigment into the dermis, which is the most stable (it is said that the dermis will not regenerate after adulthood).

Moreover, the body itself is curved, and any pattern will be deformed when put on.

Unless the bottom of the meat becomes too big or injured.

So as long as the change is not big, it will not be deformed.

Ps: the picture is transferred from the post bar (if it is a long muscle, it should be almost undistorted)
