I've figured out a bit more about how these are working, but could still use clarification from someone familiar with the source.
It appears that whatever I specify as the page size, Scribus is putting the registration marks *outside* this area, and is then increasing the size of the PDF document to accomodate this. It seems that with offset=0, the registration marks are"just barely" outside the defined page area, so that the centers are about 7mm further apart than the size of the defined page. Any additional offset gets added to this distance, and the page grows even larger to accomodate it. This is all well and good, and probably makes sense for most situations, where you have a rectangular page and want the registration marks outside that area (and probably outside the bleed area as well). CD printing is a bit different, however - at least, it is for this printer. It appears I need to get the *centers* of the registration marks exactly 165mm apart. The CD itself is only 117mm wide, so there is actually a very large margin around the printed area. It seems that defining a page size of about 158mm (165-7) smaller does the trick. Or perhaps it should be exactly 20pts smaller. I'm just kind of eyeballing it - I can't figure out a way to calculate the center-to-center distance precisely. It occurs to me that it should be possible to figure this out from the code. But I'm afraid my programmng days are long behind me. Can anyone tell me how far the center of the registration mark actually is from the edge of the page (assuming offset=0)? -------------- Marc Sabatella marc at outsideshore.com
