Abstract

A newspaper producing method can produce a plurality kinds of newspapers different in page numbers and colors by using a single printing unit. This method includes a plurality of printing cycles, each of which produces a plurality of lateral printed rows on each side of a continuous web, with each row having different contents relative to each other, with each row having at least two printed segments in a width direction of the continuous web, and with rows on opposite sides of the continuous web corresponding to each other. This printed continuous web is cut with respect to each of the lateral printed rows and each two-page spread of newspaper, and these cut portions are set and are delivered for every printing cycle. Each set of these portions is folded at a longitudinal central portion of a two-page spread thereof.

Claims

1. A method of producing newspaper, comprising:

during a printing cycle, using a digital printing machine to sequentially print onto one side of a continuous web first lateral rows of images that differ from row to row, wherein each of said first lateral rows defines at least two printing segments in a width direction of said continuous web;

during said printing cycle, using said digital printing machine to sequentially print onto an opposite side of said continuous web second lateral rows of images that differ from row to row, wherein each of said second lateral rows defines at least two printing segments in a width direction of said continuous web, and wherein said second lateral rows correspond to said first lateral rows, respectively;

cutting said continuous web longitudinally with respect to each portion thereof that is to define a two-page spread of the newspaper, and laterally with respect to each of said first and second lateral rows of images, so as to provide cut portions that define a two-page spread of the newspaper;

in correspondence with said printing cycle, combining said cut portions into a set and delivering said set towards a folding station;

at said folding station, folding said set along a longitudinal central portion thereof;

after said printing cycle and during another printing cycle, using said digital printing machine to print onto said one side of said continuous web additional first lateral rows of images;

during said another printing cycle, using said digital printing machine to print onto said opposite side of said continuous web additional second lateral rows of images;

cutting said continuous web longitudinally with respect to each portion thereof that is to define a two-page spread of another newspaper, and laterally with respect to each of said additional first and second lateral rows of images, so as to provide additional cut portions that define a two-page spread of the another newspaper;

in correspondence with said another printing cycle, combining said additional cut portions into an additional set; and

folding said additional set along a longitudinal central portion thereof.
