Reply To: Data Merge Document

when doing the merge, make the card the finished size plus bleed, don't put the crops/trims on just yet. do this once the merge is finished.

when idd does the merge, it takes the top left corner and the bottom right corner of the art on the page to be what is duplicated, so if 10-up trims are already drawn up, indesign will think that the complete imposition is what has to be merged rather than the single card.
