I'm designing some artwork for my control panel and want some bleed around the edges, so there's some excess in case I don't apply it perfectly. The problem is, if I make the background extend say an extra inch in all directions, then when I go to put it on, how will I know where the "proper" edge is meant to be? I could add a line for the edge in the art, but then that defeats the purpose of the bleed because if I don't put it on perfectly that wonky line will look really bad.
Does anyone have advice for how to have the background extending, but still be able to tell where the proper edges of the control panel are? I want some circles around the buttons so having it line up as straight as possible would be good.
