Automatically inject crosshair centre marks on every ink plate, offset from the ink bounding box, top, bottom, left and right.
Centre Marks takes a normalised PDF and injects crosshair centre marks on every ink separation, positioned off the shared artwork centre and cropped to each plate so they line up when the plates are mounted. Getting centre marks right by hand across a stack of separations is slow and easy to get wrong, this tool places them consistently in one pass, offset cleanly from the ink bounding box on all four sides, and clamps the bleed to the sheet. It runs in the browser, free to try for 7 days, and gives the plate room a reliable mounting reference on every colour.
