ABSTRACT:
Printed products having a center fold are provided with appropriate product break structure for facilitating opening of the printed products. Such product break structure comprises a crimp structure which may be in the form of impressions or embossments. This crimp structure is provided in the region of one end of the center fold of the printed products to be opened. These crimp structures mutually converge in relation to one another and extend to a common point located on the center fold of the printed products. Each of the printed products can be opened at the center fold by applying or exerting pressure on the folded edge or spine of the printed products at the end of the center fold which is provided with the crimp structure. An opening element can enter the opening thus formed for separating the two halves of each of the printed products.
