Abstract
A wrapper for a smoking article has a base web and a plurality of crenellated bands, each having a diffusivity value in the range of 0 to about 0.2 cm/sec. The add-on material can be applied by gravure printing in a single pass in a chevron pattern such that an apex of the element is co-linear with substantially symmetrically spaced points on a trailing, outer edge of an adjacent chevron element. Testing elements may be simultaneously printed with the add-on material to monitor diffusivity and/or presence of add-on material.
