Web offset press as well as method for operating the web offset press

A web-fed offset printing press comprising a plurality of I-type printing units (300) embodied as blanket-to-blanket printing units, through which a web (B;

• B′) passes essentially in a horizontal direction, a multiple folding unit assembly (800) having at least one first folding unit (800.1) and at least one second folding unit (800.2), each of said at least one first folding unit and said at least one second folding unit being adapted for forming a cross fold, wherein each of the printing units (300) has at least one forme cylinder (304) and one transfer cylinder (303) that interacts with the web (B;
• B′), wherein an effective cylinder width of the forme cylinder (304) has a width which corresponds to the printing images of at least x=8 vertical or horizontal printed pages in a DIN A4 format (A4), characterized in that a first number x;
• y;
• z of first web ribbons (bx;
• by;
• bz), produced by slitting the web (B;
• B′), are fed to said at least one first folding unit (800.1, to form a first cross fold, and at the same time, a second number y;
• x of second web ribbons (bx;
• by;
• bz), produced by slitting the same web (B;
• B′), are fed to said at least one second folding unit (800.2), to form a second cross fold, and further wherein, in one operating mode, said at least one forme cylinder carries, in its longitudinal direction, and arranged longitudinally side by side, first printing images of one of a first orientation and format and second printing images of one of a second orientation and format, said first printing images having a first forme cylinder circumferential length and said second printing images having a second forme cylinder circumferential length different from said first forme cylinder circumferential length.
