The tobacco rod (122) has a circumferential direction, a longitudinal direction (142), a lit end (124), and a mouth end (130). The wrapper (123) includes a base web (140) having generally parallel first and second side edges extending in the longitudinal direction (142) and two ends extending in the circumferential direction wherein the base web (140) is disposed around the column of filler such that the first and second side edges of the base web (140) overlap and form a seam. The base web (140) includes at least one circumferentially extending banded region (126) of fibrous crystalline cellulosic material (126) thereon. The fibrous crystalline cellulosic material (126) is in a condition of having been gravure printed on the base web (140) as a fibrous crystalline cellulosic slurry that comprises water, crystalline cellulose, and chalk wherein the fibrous crystalline cellulosic slurry has a solids content of about 10% or less by weight of the fibrous crystalline cellulosic slurry.
