1. A disposable absorbent article comprising: a) a body contacting surface;b) a garment contacting surface opposite the body contacting surface; andc) an inkjet printed wetness indicator which is seen through either the body contacting surface or the garment contacting surface; the wetness indicator
1. A disposable absorbent article comprising: a) a body contacting surface;b) a garment contacting surface opposite the body contacting surface; andc) an inkjet printed wetness indicator which is seen through either the body contacting surface or the garment contacting surface; the wetness indicator comprising a permanent hidden central graphic and a water soluble background graphic, wherein the hidden central graphic having at least one permanent ink composition and the background graphic having at least one water soluble ink composition, the central graphic and the background graphic together comprising inkjet-applied dots of the permanent ink composition that are adjacent or overlapping inkjet-applied dots of the water soluble ink composition, such that upon wetting, the background graphic exhibits a visible change resulting in the hidden central graphic being revealed, wherein the visible change is selected from the group consisting of a color change, a graphic change, and combinations thereof; and wherein the revealed hidden central graphic is visible through either the body contacting surface or the garment contacting surface; andwherein the inkjet-applied dots of the permanent ink composition have a first color, the inkjet-applied dots of the water soluble ink composition have a second color, and the respective dots are disposed adjacent each other to form a built third color. 2. The article of claim 1, further comprising a component material disposed between the body contacting surface and the garment contacting surface. 3. The article of claim 2, wherein the component material is selected from the group consisting of a backsheet, a topsheet, an acquisition layer, an absorbent core, leg cuffs, and combinations thereof. 4. The article of claim 3, wherein the backsheet is either breathable or non-breathable. 5. The article of claim 1, wherein the water soluble ink composition comprises: a) from about 1% to about 10%, by weight of the composition, of a fluid dyestuff;b) from about 1% to about 10%, by weight of the composition, of a resin;c) from about 1% to about 10%, by weight of the composition, of a plasticizer; andd) from about 50% to about 90%, by weight of the composition, of a solvent. 6. The article of claim 5, wherein the solvent is an organic solvent. 7. The article of claim 6, wherein the organic solvent is selected from the group consisting of methanol, acetone, and combinations thereof 8. The article of claim 1, wherein the wetness indicator is printed via continuous inkjet printing. 9. A disposable absorbent article comprising: a) a liquid pervious topsheet;b) a liquid impervious backsheet that is at least partially joined to the topsheet;c) an absorbent core disposed at least partially between the topsheet and the backsheet; andd) a wetness indicator inkjet printed onto a surface of either the absorbent core or the backsheet, the wetness indicator having a permanent hidden central graphic and a water soluble background graphic, wherein the hidden central graphic includes at least one permanent ink composition and the background graphic includes at least one water soluble ink composition, the central graphic and the background graphic together comprising inkjet-applied dots of the permanent ink composition that are adjacent or overlapping inkjet-applied dots of the water soluble ink composition, such that upon wetting, the background graphic exhibits a visible change resulting in the hidden central graphic being revealed, wherein the visible change is selected from the group consisting of a color change, a graphic change, and combinations thereof; and wherein the revealed hidden central graphic is visible through either the liquid pervious topsheet or the liquid impervious backsheet; and wherein the inkjet-applied dots of the permanent ink composition have a first color, the inkjet-applied dots of the water soluble ink composition have a second color, and the respective dots are disposed adjacent each other to form a built third color. 10. The article of claim 9, wherein the wetness indicator is in liquid communication with the absorbent core. 11. The article of claim 9, wherein the wetness indicator is printed via continuous inkjet printing. 12. A method of printing a wetness indicator onto an absorbent article, the method comprising the steps of: a) providing an absorbent article wherein said article comprises a liquid pervious topsheet, a liquid impervious backsheet and an absorbent core; andb) inkjet printing a wetness indicator onto a surface of the absorbent article, the wetness indicator having a permanent hidden central graphic and a water soluble background graphic, wherein the hidden central graphic includes at least one permanent ink composition and the background graphic includes at least one water soluble ink composition, the central graphic and the background graphic together comprising inkjet-applied dots of the permanent ink composition that are adjacent or overlapping inkjet-applied dots of the water soluble ink composition, such that upon wetting, the background graphic exhibits a visible change resulting in the hidden central graphic being revealed, wherein the visible change is selected from the group consisting of a color change, a graphic change, and combinations thereof; and wherein the revealed hidden central graphic is visible through either the liquid pervious topsheet or the liquid impervious backsheet;and wherein the inkjet-applied dots of the permanent ink composition have a first color, the inkjet-applied dots of the water soluble ink composition have a second color, and the respective dots are disposed adjacent each other to form a built third color. 13. The method of claim 12, wherein the backsheet is either breathable or non-breathable. 14. The method of claim 12, wherein the water soluble ink composition comprises: a) from about 1% to about 10%, by weight of the composition, of a fluid dyestuff;b) from about 1% to about 10%, by weight of the composition, of a resin;c) from about 1% to about 10%, by weight of the composition, of a plasticizer; andd) from about 50% to about 90%, by weight of the composition, of a solvent. 15. The method of claim 14, wherein the solvent is an organic solvent. 16. The method of claim 12, wherein the wetness indicator is printed via continuous inkjet printing. 17. The method of claim 16, wherein the continuous inkjet printing is binary array printing.
