Solutions to Prevent Transfer Lines: Part Two

Another way to reduce or eliminate hard paper lines from heat transfer is to tear the edge of your sublimation transfer paper. This causes a more gradual edge and also a less pronounced line so it will not be as noticeable. This is more of a Band-Aid as the lines might still be there, but it could get you over the edge if you are close to solving the transfer lines issue.
