Guides are on-screen only — never printed; keep-outs are for overprinting existing card stock. Corners: Rounded = transparent corners, the machine cuts on the image edge. Square + trim guide = artwork bleeds to a square edge with a barely-there printed curve and corner ticks for hand trimming — cutting machines ignore printed lines. For a machine-true cut on the trim line use Print & cut SVG: it carries the artwork plus a vector cut path (in Design Space select both and Flatten). Sheets auto-rotate to fit the most cards and include crop marks at the trim line. Folded stocks get four faces: outside flat (front + back) and inside flat (cover + message), both imposed so everything reads correctly once folded — duplex-flip on the short edge for top-fold, long edge for side-fold. If a flat is bigger than the sheet (A5 card = full A4 flat), export the flat PNG and print it directly. Your design autosaves in this browser; run one test print before a batch.
