Abstract: An integral printed sheet product includes a planar core formed by first and second strips of different materials positioned side-by-side, the second core strip being printed on a first major side with a plurality variable data fields, the variable data fields being spaced apart from one another on the second core strip, each variable data field being printed with a unique code, the codes printed in all of the variable data fields of the sheet product being identical. A first cover strip is integrally secured to each of the first and second core strips holding the first and second core strips in side by side position. The first cover strip only partially covers the second major planar side of the core and at least partially covers each of the first and second core strips while extending completely across the second major side of the core and the first and second core strips.

Abstract: A printed sheet product comprises a thin core having a pair of opposing major planar sides. A plurality of sets of variable data fields are printed on at least a first side of the core. One or more of the variable data fields of each set may be printed on the opposing second side of the core. Each set of printed variable data fields includes at least a first data field printed with a numeric code, the numeric code of each variable data field set being different from that of each other set printed on the first side of the core. Each set of variable data fields further includes a second data field printed with either a name and mailing address uniquely associated with a numeric code or with another representation of the numeric code. Where printed, the name and address of each variable data set differs from that of each other variable data set printed on the first side of the core.

Abstract: A printed sheet product comprises a thin core having a pair of opposing major planar sides. A plurality of sets of code fields are printed on a first side of the core. Each set of code fields is printed with a numeric code unique to the set. At least a first code field of each code field set is printed with the unique numeric code in at least a bar format. At least a second code field of each code field set is printed with the unique numeric code in at least a numeral format. The second code field of each set is spaced from the first code field of the set. A sheet product further comprises a layer of pressure sensitive adhesive applied to at least part of at least one side of the sheet product directly opposite at least part of at least one of the first and second code fields of each code field set printed on the first side of the core.
