I’m afraid a jig will not work very well for this kind of file…the indexing marks in @cynd11’s tutorial below will work better.
When inkjet printers print on paper products, the image can be shifted quite a bit because of variances in how the paper gets fed through the machine - the feed tray guides can be a little loose in most cases so you rarely hit the actual printing in the same place twice. So jigs don’t always work for this application.
