A multi-region paper structure having a transition region interconnecting relatively thinner regions is disclosed. The paper structure comprises a first region, a patterned second region, and a third region, and transition region. The transition region interconnects the patterned second region with a background matrix. The background matrix comprises the first region and the third region. The first region comprises a plurality of discrete protuberances dispersed throughout the third region. The first and second regions are disposed at different elevations, and each has a thickness less than a thickness of the transition region. An apparatus and process for making the paper structure is also disclosed. |
