What Is Lost Printing One on the Other
At 100% scale, both centred, nothing resized. A positive figure on the wider or taller side is cropped; on the other it is a blank margin.

|---|---|---|---|
| Width | 25.4 mm (1 in) each side | 6R loses it | blank band |
| Height | 25.4 mm (1 in) each end | 6R loses it | blank band |
