I have been trying to impose a DL size (210mm x 99mm) PDF onto SRA3 450mm x 320. The PDF artwork has 3mm bleed and Indesign default crop marks but I am trying to impose this 6up so I only need to utlise 2mm of the bleed. I should have a 4mm gutter between columns and rows with the 2mm bleed falling inside the gutter.
Assume I am an idiot and new to FFC (which I am, on both counts), Can someone tell me how on earth I could get this to work? This must be possible to fit in 6up as I can do it easily in InDesign.
If I understand your case. I would first use a Resize node (to eliminate the 1mm of excess bleed) -- see screensnaps. Note you need to check the reposition contents selection to get the centering you expect. The fllowing imposition node should be set with the press sheet size of SRA3. The layout to 3 rows, 2columns.
