and how do I achieve it

I am going to print business cards that I've created using LaTeX, and when I contacted the print company and asked what they needed for the print, they answered that they needed a "pdf with the correct page size, including a 5 mm bleed,

I've read up on wikipedia and understood that when you print something, you usually print it on paper that is too large, and then cut away the extra to fit the page Fountain Pen Montblanc size. This "extra" is, if I understand correctly, called bleed. Is my understanding accurate?

I intend Montblanc Cufflinks the finished Mont Blanc Rollerball Pen business cards to be 85x50 mm, printed on white paper with a faint watermark. I've Mont blanc Pen fixed the paper size with the geometry package and "underlayed" the watermark using the eso-pic package, so that's down allright. The watermark image is large enough to span almost the entire card, but it is white (transparent) all the way around the edges, so it doesn't actually touch the paper edge.

How do I achieve in LaTeX what the printers ask for? Do I simply adjust the paper size to 10 mm extra in each direction, or Mont Blanc Meisterstuck Fountain should I do something more advanced than that? If it's more advanced, how do I Discount Montblanc Pens do it
