Well you put the DPI(dots per inch) in the place where it says 72 when you start out with a new space area,hich is resolution of your graphic, and bleed is basically just the amount of space you leave blank on a graphic , so if it says .25" bleed, which is a 4th of a inch, you put that much extra space on your graphic, so when the printer cuts, it ill only leave your graphic, if you dont put bleed on your graphic, then .25" will be cut off from your graphics, n you dont want that, Hope this helped...
