Can I ask why you are stepping up the cards in InDesign? Professional printers would prefer singular cards, and they would then do the imposition.
YES! Thank you. that was exactly what I've been looking for.
I know, but we have a business card-cutter in our office, we print and cut them by ourself. It´s a small company...
Well in that case - if your cards don't have bleed you can save a cut by removing the gap in the middle.
yes, but this cutting machine has this settings and I just follow them...
