Hasbro does not publish a hole spacing, so the presets start at 6.35 mm and you replace it once with your board's real one. Measure centre-to-centre across a run of holes — the longer the run, the smaller your error.
Nothing is uploaded — the image is read and converted in your browser.
Nine possible values per hole is a very short palette. Dithering trades a flat wrong colour for a mix that reads right from a step back — leave it on for photographs, turn it off for logos and flat art.
The board previews the conversion live. Convert commits it so you can edit it by hand — and that step is undoable.
Turn off “fit to page” / “shrink to fit” in the print dialog and set the scale to 100%. Every sheet carries a 100 mm bar — measure it once with a ruler before you trust the rest.
