Printing on a web of a printing substrate

A printing system which comprises

• a printer to print on a printing substrate which is a web which is elongate in a longitudinal direction, wherein frames of a maximum printing format can be printed in a sequence on the web, and
• a control unit which is to process print data
• to arrange a plurality of pages on each of a plurality of sheets of a given sheet format, wherein the maximum printing format of the printer is larger in the longitudinal direction of the web than the sheet format, wherein pages which are adjacent in the longitudinal direction of the web are separate from each in the longitudinal direction of the web,
• to impose pages of more than one sheet into printing frames which are larger in the longitudinal direction of the web than the sheet format but not larger than the maximum printing format,
• to send frame data corresponding to the printing frames to the printer to print the frames of the imposed pages, and
• to group the pages from the printed frames to sheets on which the pages are arranged as originally.

Use of a printing system which comprises

• a printer to print on a printing substrate which is a web which is elongate in a longitudinal direction, wherein frames of a maximum printing format can be printed in a sequence on the web, and a control unit which is to process print data, wherein
• a number of pages are arranged on sheets of a given sheet format, wherein the maximum printing format of the printer is larger in the longitudinal direction of the web than the sheet format, wherein pages which are adjacent in the longitudinal direction of the web are separate from each in the longitudinal direction of the web,
• pages of more than one sheet are imposed into printing frames which are larger in the longitudinal direction of the web than the sheet format but not larger than the maximum printing format,
• frame data corresponding to the printing frames are sent to the printer to print the frames of the imposed pages,
• the pages from the printed frames are grouped to sheets on which the pages are arranged as originally,
• wherein the pages which are arranged on the sheets have a given size in the longitudinal direction of the web,
• wherein an integer number M of pages are arranged on a sheet in the longitudinal direction of the web, and
• wherein an integer number N of pages from more than one sheet, N being larger than M, are imposed into one printing frame which is larger in the longitudinal direction of the web than the sheet format but not larger than the maximum printing format.
