Systems and methods are provided herein for applying sacrificial material to otherwise uncoated areas of a foil to provide uniform pressure during calendering. For example, one or more portions of a foil may be coated with an active material while other portions of the foil may be coated with an appropriately selected alternate material. After the active material and the alternate material are applied to the foil, the foil may be dried and then calendered. During calendering, the compressive force of the rollers can cause the portion of the foil coated in the active material to stretch a similar amount to the portions of the foil coated in the alternate material. The resulting calendered web has minimal wrinkles due to the similarity of the stretching of the foil coated in the active material and the foil coated in the alternate material.
