I have a workflow where once imposed it will be a 2 sided image, that bit is fine, what i want to do as the final step is to move the whole imposition, including the cropmarks by 3mm to the right on side 1 and 3mm to the left on side 2, so both sides end up physically shifted to one side by 3mm on the sra3 sheet, ive tried to do this using the resize node placement, but it doesnt move the cropmarks, they stay central, can anyone suggest a way that will move the cropmarks as well?
One solution is to use the Imposition node Horizontal Alignment feature. If "Binding Edge" is selected the imposition of the pages will use the left side followed by the right side of the sheet for the reference edge. Then use the "Horizontal Alignment" to get the shift that you desire. The put both pages in center use the formula of halfthewidthoftheimposedsheet - halfthewidthoftheimposedpage. For example if the press sheet width is 18inches and the page width is 8.5 inches, the horizontal alignment = 9 - 4.25.
The crop marks will move with the horizontal alignment.
