how to center document & align it with punch mark on fil

[HKFriedRiceChef]

Hi all Prepress Experts. I need help here. My question is how can I center my preps document on film so that the center of the document(registration mark) align with the center punch mark on the film. I got my document page align on the left side. When I use Quark to sent imposition page, I choose "center" from Quark print dialog box, the document will be in the center of the film, & so does the punch mark.(the center registration mark will align with the center punch mark on the film) However, Preps print dialog box doesn't has "center" option. Is there any where I can set it in Preps. panic...
*I am using Preps 4.2 in OSX classic, postscript workflow. Help~~~~
*the first film I got rotated the wrong direction & got chop off, punch marks are on the right side. Then, I choose rotation"1" from device set up under custom page. Then, I got it rotate right, but document is not in the center of the film????by the way, what is rotation"0" "1" "2" , etc???????
*straight 9hrs working without break & lunch, 1 man solo...>_<

One Question......Have you used Preps before now ?

Guest. you are very rude. get out of here!!!

HK sounds like on the initial install your output device was never calibrated for center and pin configs. If you are new to preps this will be a very frustrating area to accomplish. If it is a recent install, I'd try getting in touch with your dealer and have them reconfig to your output device.

finally, I got everything centered on the film, except there is an 1/16" space less between the press sheet & punch marks???
