A high speed embossing and adhesive printing process using a first and second embossing rolls having complementary embossing pattern disposed thereon. A web of sheet material is placed in contact with an adhesive applied to the first embossing roll. The adhesive forms an adhesive pattern on the web of sheet material in register with the first embossing pattern of the first embossing roll. The web of sheet material is then passed between the first and second embossing rolls which emboss the web with the complementary embossing pattern.

1. An embossing and adhesive printing process, said process comprising the steps of:(a) supplying a first embossing roll having a first embossing pattern disposed thereon, wherein said first embossing roll as engaged with a second embossing roll, said second embossing roll having a second embossing pattern disposed thereon, said first embossing pattern and said second embossing pattern being complementary; (b) applying an adhesive to said first embossing roll; (c) contacting a web of sheet material with said first embossing roll after step (b), wherein said adhesive forms an adhesive pattern on said web of sheet material in register with said first embossing pattern of said first embossing roll; and, (d) passing said web of sheet material between said first embossing roll and said second embossing roll wherein said first embossing roll and said second embossing roll emboss said web with said complementary embossing pattern. 2. The process of claim 1, further comprising the steps of:(e) prior to step (b), applying said adhesive to a roll rotating at an initial tangential speed; (f) accelerating said adhesive through a series of metering gaps between a plurality of adjacent adhesive rolls; (g) applying said adhesive to an adhesive application roll rotating at a tangential line speed which is higher than said initial tangential speed; and, (h) transferring said adhesive from said adhesive application roll to said first embossing roll. 3. The process of claim 1, further comprising the steps of:(i) removing said web of sheet material from said first embossing roll. 4. The process of claim 3 wherein the temperature of said first embossing roll at step (i) is lower than the temperature of said first embossing roll at step (b).5. The process of claim 1, further comprising the step of:(j) cooling said web of sheet material. 6. The process of claim 5 wherein said web of sheet material is cooled by cooling at least a portion of said first embossing roll.7. The process of claim 6 wherein said first embossing roll is internally cooled.8. The process of claim 6 wherein said first embossing roll further comprises a circumferential outer surface and wherein said outer surface is heated prior to step (b).9. The process of claim 1, wherein said adhesive is selected from the group consisiting of hot melt adhesives, pressure sensitive adhesives, water based adhesives, water borne adhesives, solvent based adhesives, ultra-violet cured adhesives, e-beam cured adhesives, and combinations thereof.10. The process of claim 1, wherein either of said first embossing roll or said second embossing roll is heated.11. The process of claim 1, wherein said first embossing roll is a female embossing roll and said second embossing roll is a male embossing roll.12. The process of claim 1, wherein said first embossing roll is a male embossing roll and said second embossing roll is a female embossing roll.13. The process of claim 1, wherein said first embossing roll includes a release surface.14. The process of claim 1, wherein at least a portion of said first embossing roll is heated before step (b).15. The process of claim 1 wherein said adhesive applied to said web of sheet material has a basis weight of less than 3 g/m2.16. The process of claim 1 wherein after step (c), cooling said web of sheet material.17. An embossing and adhesive printing process, said process comprising the steps of:(a) supplying a first embossing roll with a first embossing pattern having lands and recesses disposed thereon, wherein said first embossing roll is engaged with a second embossing roll, said second embossing roll having a second embossing pattern disposed thereon, said first embossing pattern and said second embossing pattern being complementary; (b) passing a web of sheet material between said engagement of said first embossing roll and said second embossing roll wherein said first embossing roll and said second embossing roll emboss said web of sheet material with said complementary embossing pattern; and, (c) applying an adhesive to said sheet of web material after step (b), wherein said adhesive is applied into said recesses of said embossed sheet of web material. 18. The process of claim 17 wherein said adhesive is applied by an application roll having an adhesive printing pattern complementary to said first embossing pattern of said first embossing roll.19. An adhesive coated sheet material which comprises:an adhesive deposited within each embossing roll having a first embossing pattern web of sheet material by supplying a first embossing roll having a first embossing pattern disposed thereon, wherein said first embossing roll is engaged with a second embossing roll, said second embossing roll having a second embossing pattern disposed thereon, said first embossing pattern and said second embossing pattern being complementary, applying said adhesive to said first embossing roll, contacting said web of sheet material with said first embossing roll, wherein said adhesive forms an adhesive pattern on said web of sheet material in register with said first embossing pattern of said first embossing roll, and, passing said web of sheet material between said first embossing roll and said second embossing roll wherein said first embossing roll and said second embossing roll emboss said web with said complementary embossing pattern.
