Poznámky

Pokud měříte okraje v milimetrech, vynásobte požadovanou šířku okrajů v milimetrech hodnotou 3,937, abyste určili správnou míru v setitinách palce. Pokud například chcete mít okraj 25 mm, vynásobte 3,937 a výsledek je 98 zaokrouhleno dolů. Potom byste nastavili odpovídajícího Margins člena na 98.
