Claims

What is claimed is:

1. A sheet of tissue wherein said tissue is a macroscopically monoplanar through air-dried multi-density tissue having low density regions extending outwardly from the plane of said tissue, said tissue having two opposed faces, at least one of said faces having a smoothness less than or equal to about 600 microns, said at least one face having micropeaks thereon, said micropeaks having a micropeak height of at least about 0.05 millimeters.

2. A sheet of tissue according to claim 1, said tissue having a smoothness less than or equal to 550 microns.

3. A sheet of tissue according to claim 2, said tissue having a density of at least about 0.130 grams per cubic centimeter.

4. A sheet of tissue according to claim 1, said tissue having a caliper less than about 0.8 mils.

5. A sheet of tissue according to claim 1, having a micropeak height of at least about 0.10 millimeters.

6. A sheet of tissue according to claim 5, having micropeak height of at least about 0.12 millimeters.

7. A sheet of tissue wherein said tissue is a macroscopically monoplanar through air-dried multi-density tissue having low density regions extending outwardly from the plane of said tissue, said tissue having two opposed faces, at least one of said faces having a smoothness less than or equal to about 600 microns, said at least one face having micropeaks thereon, said micropeaks having a micropeak height, a micropeak width and a micropeak frequency.

8. A sheet of tissue according to claim 7, having a micropeak height of at least about 0.10 millimeters.

9. A sheet of tissue wherein said tissue is a macroscopically monoplanar through air-dried multi-density tissue having first and second opposed faces and low density regions disposed on said first face and extending outwardly from the plane of said tissue, said second face having a smoothness less than or equal to about 600 microns, at least one said face having micropeaks with a micropeak height of at least about 0.05 millimeters.

10. A multidensity sheet of tissue wherein said tissue is a macroscopically monoplanar through air dried tissue having micropeaks extending outwardly from the plane of said tissue, said tissue having two opposed faces, at least one of said faces having a smoothness less than or equal to about 600 microns, said at least one face having micropeaks with a micropeak height of at least about 0.05 millimeters.
