Abstract: 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.

Abstract: A printing technology wherein an endless belt-shaped printing plate is wound about a plate cylinder and a guide roller of a printing cylinder and, by using the printing plate, a continuous form sent between the printing plate and an impression cylinder is printed. In the plate cylinder, feed pins are disposed in rows at an even pitch along an outer periphery of the cylinder. The feed pins are guided by a fixed cam ring and project and retract freely and project in a desired region of the plate cylinder, respectively with respect to the cylinder surface. Pin feed holes are provided in rows in marginal zones of the endless belt-shaped printing plate. The endless belt-shaped printing plate is formed by joining and bonding both ends of an elongated resinous relief printing plate with an adhesive tape from the printing surface side. The pin feed holes are engaged with the feed pins of the plate cylinder, whereby the plate feed is guided.

Abstract: A notebook is produced through a process, including the steps of: successively printing a multiplicity of unit forms including ruled lines formed of a succession of micro characters by the a first printer equipped with an endless belt-shaped printing plate on one surface of a continuous web form supplied from a feed roll; inverting the front and back surfaces of the continuous web form with a form inverter; printing on the other surface of the continuous web form by a second printer equipped with an endless belt-shaped printing plate to provide the continuous web form with prints on both surfaces; folding up zigzag the continuous web form for every unit form to pile up the zigzag-folded continuous web form on a stack, and cutting and separating the continuous web form for every preset number of consecutive unit forms, thereby providing a notebook including a group of the preset number of consecutive unit forms which have been printed on both faces thereof and spreadably zigzag-folded.
