Our typeface technology has adapted to shifts in media across the generations, from metal printing blocks to computer phototypesetting and later, digital. To remain compatible with the digital age, modifications were made to 120,000 typesetting characters beginning in 2005 – an effort that took seven years.

Printing technology


Technology to process base materials such as metals, glass and resins with high precision and accuracy, and to give them the effects and functions necessary to achieve a desired goal.

Microfabrication: Origin and development

Photolithography technology

A technique to duplicate images onto the surface of a substrate coated with photosensitive material by exposing original images using shining light or electron beams. This technology is used in the printing process to produce printing plates from photographic film originals of images and lettering, and has been applied in industries that demand precision, such as electronics.

Precision engraving technology

An engraved cylinder used in photogravure printing is configured as an aggregate of individual concave cells of the text and pattern, which are engraved by varying their size and depth. These engravings range from those manually carved by a craftsman to those made using micro-order and nano-order precision cutting equipment. The appropriate technology is employed in line with the desired objective.

Molding technology

Molding technology is applied to printing substrates to replicate uneven shapes, such as the text or geometrical patterns formed in the metal, glass or resin molds originally used. It was developed from an embossing process performed to align printing patterns and from the machining of lenticular lenses used for 3D printing.

Etching processing technology

A technology for processing desired structures by chemically corroding and removing materials. This technology has evolved from the printing process, including resin letterpress and photogravure plate manufacturing technology. When used in combination with photo-engraving technology, it is possible to produce fine and high quality plates.

Hologram technology

We have conducted R&D on techniques for recording and printing 3D images. We use two methods in this area: one to record the intensity and phase of laser reflected light from a real model directly onto a photosensitive material using the interferometric property of laser light, and another to record computer-calculated optical interference fringe data directly by electron beam lithography.

Precision coating

Technology to form homogeneous and uniform coating films from various materials in single or multiple layers on the surface of base materials such as paper, resin, metal and glass.

Precision coating: Origins and development

Printing technology

This is a general term for a process that applies ink to a printing plate prepared from manuscripts, including text and images, and transfers the ink to a substrate such as paper, facilitating the high-speed, high-volume reproduction of manuscripts. Toner-based printing and ink jet printing developed in recent years do not require a printing plate, and by controlling the ink transfer volume, it is possible to print directly from digital manuscript data.

Vacuum film deposition (dry coating) technology

A technology for coating a super-thin film onto substrate such as plastic film by applying evaporated substances in a vacuum. This technology has made it possible to manufacture the high-precision glass / thin metal master plates required in the semiconductor manufacturing field.

Coating technology

A process for applying ink in a thin, uniform fashion to the surface of the material substrate, including wet coating – where coating resins or materials such as ink are applied as a coat – and dry coating, including metal deposition. By combining this technology with design technology for the base material, it is possible to configure coatings with different functionality, including optical properties, barriers and heat-resistant features.

EB and UV curing technology

A technology that instantly cures resin and coating film materials by exposing them to electron beam (EB) or ultraviolet light (UV). This technology has evolved to significantly shorten coating resin and ink drying time in the printing process. It allows for energy savings in the production process, CO2 reductions, solvent-free coating and the facilitation of clean coating processes with a low environmental burden.


Technology to achieve safety, durability and convenience required for the environment in which products are used for their intended purpose

Post-processing: Origin and development

Bookbinding technology

Bookbinding is the process of arranging printed pages into book form. Various methods are used for each of the basic steps of folding, binding and trimming the paper, including processes for making pop-up and double-leaved books.

Transfer processing technology

Instead of pressing ink directly to a substrate, printing elements are applied to a carrier film, and then pressed onto the substrate with heat. The substrate can be plastic, glass, metal or other material.
Transfer processing is widely used for decorative films, and also for designing containers and interior components for vehicles.

Laminating technology

This technology is used for evenly laminating materials like film, metal and resin. It provides high performance for multiple functionalities, including as a water vapor barrier, or in terms of durability.
