Methods to exchange printing substrate rolls in a printer are described. In an exchange method, ink is printed to a first printing substrate web being unwound from a first printing substrate roll. The first printing substrate web is exchanged with a second printing substrate web being unwound from a second printing substrate roll. A transition region of the first and the second printing substrate webs is printed to during the exchange of the first and the second printing substrate webs. The transition region can be formed by gluing the second and the first printing substrate webs atop one another. A predetermined pattern can be printed onto the transition region during the exchange of the printing substrate rolls. The predetermined pattern can be chosen such that all nozzles of at least one print head are used for printing.
