[Scribus] Crop marks

[Khiraly]

Dear list,

My problem is the following:
I have a document in specific format:
210mm*396mm

The prepress bureau use the following paper size:
sr-A3 320mm*450mm

So I must center my document on a sr-A4 document, and place some  CROP
MARKS.

- What is the easiest method to center on a bigger papersize a smaller
document (so on a 320mm*450mm I want to place a 210mm*396mm document).
  I can write manually, that the margins are:
left: 55mm
right: 55mm
top: 32mm
bottom: 32mm
( in the page properties. But scribus dont place on the printable area
(ie. not exactly o the center)

- How can I place CROP MARKS on the page for the prepress? Is it really
important because I want to print a double sided document.
- Can I place automatically? (if I set correctly the margins values, the
crops marks should be in the right place)

Thx in advance.

Best regards, 
 Khiraly

ps: sorry for my ugly english.
