Removing the perforated margins
To remove the perforated margins, fold the paper back and
forth a few times along the perforations, then carefully tear
the margins off.
You can also remove the margins by cutting along the
perforations.
Note:
Keep in mind that the edges of your image might be cut off when you
remove the perforated margins. See the illustration below.
