Basic Technologies

Letterpress printing was a state-of-the-art technology in Japan when DNP was originally founded as a letterpress printing firm. Since then, the company has branched out into various businesses by developing and applying printing technologies. The diverse technologies and expertise that underpin our wide range of printing operations and services are highlighted in the following pages through the example of the processes involved in printing a book.

DNP's Technologies Seen through the Printing Process

Printing Process

Technologies used at this stage of the printing process

  1. 1

    Project Planning
    Envisioning what output will be printed

    Project planning and designing

  2. 2

    Information Processing
    Preparing the manuscript for printing

    Information processing technologies

  3. 3

    Film and plate making
    Making a printing plate

    Micro fabrication technology

  4. 4

    Transferring ink onto paper

    Precision Coating

  5. 5

    Binding and Post-processing
    Folding, gathering, and binding

    Post-processing technologies

    Multiple pages of a book are printed on large sheets of paper that are folded and layered for binding according to page order. Subsequently, the edges of the pages are trimmed down to final shape. For high-grade bound books with elaborate covers, the pages are enclosed after trimming. The shape of a book matches its function.

    Printed pages gathered and bound to form a book

    • Folding and gathering
      Printed pages folded and assembled by page number

    • Binding
      Printed pages are bound and attached to the cover.
      Saddle-stitch binding
      Perfect binding
    • Trimming
      Three sides of the pages are cut according to final dimensions

    Technologies used at this stage of the printing process

    Post-processing technologies

    Post-processing technologies/print finishing technologies are derived from various processes that follow the printing press, such as bookbinding. These technologies are applied to make books and other printing products easy to read and suitable for their use and purpose. While the technologies originated in bookbinding, paper cutting and assembly processes, they also led to the development of other processes, including aseptic filling.
