Hi Prasanna,

We have an excellent article about bleeds here: http://www.bestprintingonline.com/bleed.htm and an article about setting up an InDesign document here: http://www.bestprintingonline.com/indesign.htm#basics

Margins are up to the designer, but I would keep all type at least an eighth of an inch (.125") away from the final trim area. On documents with more than 24 pages I would increase this safety margin to at least one quarter inch (.25") to account for shingling. Shingling is what happens to the center pages of saddle-stitched books with a lot of pages. If you open a magazine flat you'll notice that the center pages are not as wide as the cover pages because as more pages meet at the spine the center pages are pushed out more and when the book is given it's final trim, the center pages end up narrower than the rest. A commercial printer will compensate for shingling by moving the inside pages slightly towards the spine so that the page numbers (typically on the outer edge of the page) will fall in the same spot when you flip through the book. For this reason, it's a good idea to avoid crossovers on big books and to increase the margins for the inside of pages.

Hope this helps,
