:''You may be looking for the uniform polyhedron sometimes known as "gocco", the great cubicuboctahedron.'' is a self-contained compact color printing system invented in 1977 by Noboru Hayama. Gocco became immensely popular in Japan and it is estimated that one-third of Japanese households own a Print Gocco system. The printing mechanism is that of screen printing. The Gocco sets included the materials and tools to both make the screens, and to use these screens for printing. As the Gocco screens are quite small, they were most widely used for printing greeting cards, a popular need within Japanese culture. Gocco could also print to fabrics, although only across a small area. The Gocco printing screens did offer good registration, so two or more colour printing was practical and popular. The name "print gocco" is derived from the Japanese word , loosely translated as make-believe play. Riso Kagaku president Noboru Hayama explained, "We (kids ) learned rules and knowledge through make-believe play. The spirit of play is an important cultural asset. I thought that I wanted to leave "play" in the product's name." == Printing method == The Gocco process was scaled down, but otherwise very similar to large commercial screen printing techniques. The equipment included simple plastic holders for screen making and printing. Screen printing uses a mesh screen that is coated with an impermeable paint-like material to make a stencil of the design. The ink can pass through the bare mesh, but is stopped by the impermeable stencil material. These screens are made by the printer before use, either by painting the stencil material only where it is needed or more commonly, as with the Gocco, by a simple photographic process. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gocco」の詳細全文を読む スポンサード リンク
