Abstract
An odor control substrate that is applied with an activated carbon ink is provided. The activated carbon ink is applied in a pattern that covers from about 25% to about 95% of the surface area of the substrate. Although not covering the entire surface, the present inventors have discovered that the activated carbon ink is still capable of providing good odor reduction qualities to the substrate. To further enhance the aesthetic appeal of the odor control substrate to a consumer, one or more colored inks may also be applied the substrate in a pattern that may or may not overlap with the activated carbon ink pattern. The colored ink(s) may contrast well with the activated carbon ink to provide an overall design that is more aesthetically than otherwise would be provided by a uniform coating of activated carbon ink.
