A method of making a bonded and creped type absorbent paper web that has improved bulk to peel strength characteristics includes steps of (a) printing a low density pattern of a bonding material onto a first and a second side of a paper web; and (b) in no particular sequence with respect to step (a), printing a high density pattern of a bonding material onto the first side of the paper web. Steps (a) and (b) are performed so that the high density pattern of bonding material penetrates into the paper web by a distance that is about 166 to about 470 percent of the distance by which the low density pattern of bonding material penetrates into the web. This results in a web that has superior bulk and peel strength characteristics. Another characteristic of the product is that it has a visible depression pattern in one surface, but not the other surface, which creates an attractive aesthetic effect and has functional benefits as well.

[ What is claimed is:] [1.] A method of making a bonded and creped type absorbent paper web that has improved bulk to peel strength characteristics, comprising steps of:(a) printing a low density pattern of a bonding material onto a first and a second side of a paper web with a gravure roll that has a pattern defined thereon to a depth that is from between about 30 to about 100 microns;(b) in no particular sequence with respect to step (a), printing a high density pattern of a bonding material onto the first side of the paper web, steps (a) and (b) being performed so that the high density pattern of bonding material penetrates into the paper web by a distance that is about 166 to about 470 percent of the distance by which the low density pattern of bonding material penetrates into the web, said high density pattern being visible only on the first side of the web; and(c) creping the paper web to a degree that is sufficient to impart a significant degree of bulk to areas of the paper web that have the low density pattern of bonding material printed thereon, but not the areas of the paper web that have the high density pattern printed thereon, whereby both superior bulk and peel strength characteristics are imparted to the absorbent web product.
