Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は地図表示盤等の等高線描写方式に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a contour drawing method for a map display panel or the like.
従来、この種の地図表示盤等の等高線描写は等高線の
高度に対応して緑、浅緑、薄茶、茶等の多色印刷の地色
および濃さを変えて高低を表現していた。Conventionally, this type of contour display on a map display panel or the like expresses the height by changing the ground color and density of multicolor printing such as green, light green, light brown, brown, etc. in accordance with the height of the contour line.
上述した従来の等高線描写方式は印刷での等高線の描
写に際して、多色の地色を変えて表現したいたので、使
用色の種類に応じて複数回の印刷工程が必要であった。In the above-described conventional contour line drawing method, when rendering contour lines in printing, a multicolor ground color is changed and expressed, so that a plurality of printing steps are required according to the type of color used.
本発明の等高線描写方式は地図表示盤等の等高線描写
方式において、等高線で囲まれた面積内を一色の印刷に
よる網点の密度を変えることにより高低を表現してい
る。In the contour line drawing method of the present invention, in a contour line drawing method such as a map display panel, the height is expressed by changing the density of halftone dots by printing one color in the area surrounded by the contour lines.
次に、本発明について図面を参照して説明する。 Next, the present invention will be described with reference to the drawings.
第１図は本発明の一実施例の説明図である。第１図の
実施例は３段階の高低を表現したものであり、低高度の
領域１、中高度の領域２、高高度の領域３にそれぞれ対
応して網点の密度を変えることにより高低を表現してい
る。第１図に示すように低高度の領域１から高高度の領
域３に向かって網点を段階的に高密度印刷として高度感
覚を表現している。なお、この印刷は一色の網点印刷で
行なわれる。FIG. 1 is an explanatory view of one embodiment of the present invention. The embodiment of FIG. 1 expresses three levels of elevation, and the elevation is changed by changing the density of halftone dots corresponding to the low-altitude area 1, the medium-altitude area 2, and the high-altitude area 3, respectively. expressing. As shown in FIG. 1, halftone dots are gradually printed from a low altitude area 1 to a high altitude area 3 to express a sense of altitude as high density printing. This printing is performed by halftone dot printing.
以上説明したように本発明は地図表示盤等の等高線表
示方式において、網点の密度により高低を表現するとに
より、地色が一色となり印刷が一工程で済むという効果
がある。As described above, according to the present invention, in a contour display method such as a map display panel, when the height is expressed by the density of halftone dots, there is an effect that the ground color becomes one color and printing is completed in one process.
