Design producing technology for metal etching maps

Abstract

A technology for preparing the etched metallic map includes such steps as designing the map draft, adding white edges to the profiles of signs, graphics, characters and numerals in map, combining them together, putting the combination of signs, characters and numerals on the combination of graphics, regulating the colors except white to black, copying to obtain film, cleaning metal plate, coating photosensitive liquid, optical copying, etching, removing photosensitive film and filling paint. Its advantages are clear layers and high visual effect.

Description

technical field [0001] This invention relates to a process for etching maps on sheet metal. The invention combines the authority, standardization and practicability of the printed map with the artistic decoration of the metal etching handicraft, and develops another type of map product—the craft metal etching map. Background technique [0002] A map is a map that uses certain mathematical rules and symbol systems to comprehensively and abbreviate the geographical elements of the earth's surface or a certain part of it on a plane, and generally reflect their geographical distribution and interrelationships. Since there are many types of geographical elements on the map, such as: highways, railways, towns, etc., and different types of elements overlap each other on the same plane, such as: highways, railways, towns, etc. overlap each other. At present, what are sold in the domestic and foreign markets are color printed maps that can generally reflect their geographical distri...

[0003] And the artwork film of the process metal etching map can only be a grayscale film

It applies the color printing map artwork Figure 1, adjusts the different colors (except white) in the artwork in Figure 1 to black, converts to grayscale mode, and outputs the printing film figure 2 ;according to figure 2 To make a craft metal etching map, the overlapping elements of different types on the map will blend together in the same depression of metal etching, destroying the integrity, independence and hierarchy of symbols, graphics, characters, and numbers of different types of elements sense; when filling the metal-etched depression with color, the colors at the junction are mixed together, which makes the effect of the product poor
