File preparation

Crop marks and bleed marks are areas that I would like to learn more about and how to utilise properly. They are tools I just simply have never taken the time to set up in my work. I am so used to printing at home where a white border doesn't really matter, or I have cut it off on a double sided page where it will obviously mess up one side. But I know that if I paid more attention it could save time and leave room for error.
