Abstract

A method for alignment of a pattern printed on a material for an absorbent article by a rotary printing device, including providing a first composition from a first chamber; providing a second composition including a detectable agent from a second chamber; wherein the first composition from the first chamber and the second composition from the second chamber are supplied to the same anilox roller or directly to the same rotary printing cylinder; and printing the first and second compositions on the material for an absorbent article by a rotary printing cylinder.

First claim

The invention claimed is:

1. A method for alignment of a pattern printed on a material for an absorbent article by a rotary printing device, comprising:
a. providing a first composition from a first chamber;
b. providing a second composition comprising a detectable agent from a second chamber;
c. wherein the first composition from the first chamber and the second composition from the second chamber are supplied to a same anilox roller or directly to a same rotary printing cylinder;
d. and printing the first and second composition on the material for an absorbent article by a rotary printing cylinder;

wherein the first composition comprises a functional agent selected from a skin beneficial agent, an adhesive, a cooling or heat generating agent, or an antimicrobial agent; and wherein the second composition comprises a detectable agent that emits light in the UV fluorescent or visible light spectra; and wherein the second composition also comprises the first composition.

2. The method according to claim 1 , wherein the first and second chambers are combined in one chamber with two separate compartments.

3. The method according to claim 1 , wherein each chamber has an outlet for supplying composition to the anilox roller or rotary printing cylinder.

4. The method according to claim 1 , wherein the first and second chambers are horizontally oriented in relation to the anilox roll.

5. The method according to claim 1 , wherein the first and second chambers are vertically oriented in relation to the anilox roll and wherein the outlets from the chambers are horizontally orientated in relation to the anilox roll.

6. The method according to claim 1 , wherein the rotary printing device is a flexographic printer.

7. The method according to claim 1 , wherein the anilox roll is banded.

8. The method according to claim 1 , wherein a banded anilox roll has different transfer volumes and/or line counts for the first and second compositions respectively.

9. The method according to claim 8 , wherein the areas with different transfer volumes and or line counts are separated by an area/band without transfer.

10. The method according to claim 1 , wherein the material for the absorbent article has a first and a second transversal edge.

11. The method according to claim 1 , wherein the first composition may be printed >0.1 mm from a first edge of the material and up to and including 99% of the width of the material.

12. The method according to claim 11 , wherein the second composition is printed >0.1 mm from a second edge of the material and up to and including 50% of the width of the material.

13. The method according to claim 1 , wherein the method further comprises an additional step of removing a sync mark.

14. The method according to claim 1 , wherein the first and second compositions are printed with different printing patterns.

15. The method according to claim 1 , wherein the first and second compositions are printed with different frequencies.

16. The method according to claim 1 , wherein the first and/or second compositions comprise microcapsules.

17. The method according to claim 1 , wherein the first and/or second compositions comprise a water emulsion of a skin beneficial agent.

18. The method according to claim 1 , wherein the first and/or second compositions comprise water-based ink.

19. The method according to claim 1 , wherein the material for the absorbent article is a nonwoven, airlaid, film, laminate, highloft nonwoven, cellulose tissue or a combination thereof.

20. The method according to claim 1 , wherein the absorbent article is a feminine or light incontinence napkin or pad.
