Abstract
In various examples, a master press and a slave press may be synchronized. A signal associated with the master press printing a first frame on a first web may be received. A point in time may be determined at which the slave press should begin printing, on a second web, a second frame corresponding to the first frame. The determining may be based on the signal associated with the master press and a first distance between the slave press and a downstream location at which the first and second webs converge. The slave press may be operated to begin printing the second frame at the point in time.

A computer-implemented method for synchronizing a master press and a slave press, the method comprising:
- receiving a signal associated with the master press printing a first frame on a first web;
- determining a point in time at which the slave press should begin printing, on a second web, a second frame corresponding to the first frame, wherein the determining is based on the signal associated with the master press and a first distance between the slave press and a downstream location at which the first and second webs converge;
- and
- operating the slave press to begin printing the second frame at the point in time so that the first frame and the second frame are to arrive at the downstream location at a substantially same time while the slave press is positioned in parallel with respect to the master press.
A printing press comprising circuitry to:
- receive a signal from a remote printing press, wherein the signal indicates a first moment in time at which the remote printing press begins printing a first frame on a first web;
- determine a second moment in time at which the printing press will begin printing, on a second web, a second frame intended for combination with the first frame in a product, wherein the determination is based on the first moment in time and a distance between the remote press and a finishing unit at which the first and second webs converge;
- and
- operate the printing press to begin printing the second frame at the second moment in time so that the first frame and the second frame are to arrive at the finishing unit at a substantially same time while the printing press is positioned in parallel with respect to the remote printing press.
