Abstract
A method of marking an absorbent article which has a liquid pervious top sheet, a liquid impervious back sheet, and an absorbent body enclosed there between. The method includes providing at least one strip on an inside of the back sheet material, i.e., on the side adjacent the absorbent body, wherein a color or tint of the strip is different from the rest of the back sheet material and wherein the color or tint of the strip is selected so as to be an indication of product type, product size, or product absorption capacity of the absorbent article; and arranging a wetness indicator on or adjacent the at least one strip on the inside of the liquid impervious back sheet so that the wetness indicator is visible through the back sheet material.
