1. A printing press comprising:
- at least one dry offset printing unit operating without a dampening unit and having a first machine alignment;
a dryer associated with said at least one dry offset printing unit;
means for feeding a first web through said at least one dry offset printing unit, and without a subsequent drying process, in a first production mode of said at least one dry offset printing unit;
means for feeding a second web through said at least one dry offset printing unit and through said dryer in a second production mode of said at least one dry offset printing unit;
an inking unit of said at least one dry offset printing unit and containing ink, said ink being usable in both of said first and second production modes of said printing press; and
a second printing unit including a former assembly and having a second machine alignment parallel to, and spaced from said first machine alignment, and with said at least one dry offset printing unit and said second printing unit being separated laterally from each other, said second web printed in said at least one dry offset printing unit and fed through said dryer in said second production mode of said at least one dry offset printing unit being fed, together with a web printed in said second printing unit and without a subsequent drying process, to said former assembly in a mixed production mode of said printing press.

Abstract
A printing press is comprised of at least one dry offset printing unit. At least two different webs can be fed through the dry offset printing unit. In a first production mode “C” of the printing press, a first web is fed through the dry offset printing unit without a subsequent drying process. In a second production mode “H” of the printing press, a second web is fed through the dry offset printing unit and through an active dryer. In both the first and second production modes “C”, “H”, an inking unit of the printing unit is filled with the same ink.

15. A method of operating a printing press including:
-
providing a dry offset printing unit operable without a dampening agent and including an ink supply; providing a web dryer; locating said web dryer downstream, in a direction of web travel, and in a first machine alignment of said dry offset printing unit; operating said dry offset printing unit a first production mode; supplying a first web to said dry offset printing unit in said first production mode; operating said dry offset printing unit in a second production mode; supplying a second web, to said dry offset printing unit in said second production mode; directing said second web through said dryer; maintaining said ink supply to said dry offset printing unit the same in both of said first production mode and said second production mode; providing a second printing unit, including a former, and having a second machine alignment parallel to, and spaced from said first machine alignment and with said at least one dry offset printing unit and said second printing unit being separated laterally from each other; printing a web in said second printing unit; feeding said second web printed in said dry offset printing unit and directed to said dryer to said former assembly; and combining said second web and said web printed in said second printing unit and without subsequent drying with said second web at said former assembly in a mixed mode of production of said printing press. - View Dependent Claims (16, 17, 18, 19)
