Notebook and process for production thereof

摘要

A notebook including a group of a preset number of consecutive unit forms which are printed on both faces thereof and spreadably zigzag-folded is produced through a process that includes: printing on both surfaces of a continuous web by two printers each equipped with an endless belt-shaped printing plate, with intermediate inversion of the two surfaces of the web, followed by zig-zag folding and cutting and separating the printed web for each of the preset number of forms. The obtained notebook is capable of preventing falsification and missing pages by inclusion of a horizontal ruled line provided in a main data region and formed of a succession of micro characters.
