Abstract

A METHOD of MANUFACTURING MULTI-COLOR SPACE PHOTO CARDS, including obtaining a black-and-white space photo-map, a cartographic original of a multicolor background thematic load and an original of a black-and-white stroke load, making from a cartographic multi-color background thematic load of raster photoforms by the number of color paints, black-and-white line load, making from a cartographic multi-color background thematic load of raster photoforms according to the number of color paints, black-and-white line-load, making from a cartographic multi-color background thematic load of raster photoforms by the number of color paints, black-and-white line-load of a raster photoform for the subsequent reproduction of the photographic image of the Earth's surface in black, making printed x forms and print run of multicolor photo cards, characterized in that, in order to increase the sharpness, consistency and reliability of a multicolor space photo card, three color separated photonegatives for the blue, yellow and purple colors of the triad are made from the cartographic background color separations, with black -white kosmofotoplan surface. The land is made normal - with accurate gradation characteristics - and contrasting half-tone photonegatives, form a multicolor cosmo otoizobrazhenie by making the collection | raster photoforms, for triad inks, conclude in successively combining a normal photonegative with each of the three color-dependent photonegatives, rasterizing them, and rasterizing the contrast photonegativa and combining with the original a black and white bar chart load; it is made with a decrease, and during the period of color separation it is increased to the scale of publication of the space photo card.

Description

FIELD OF THE INVENTION The invention relates to cartographic production, in particular to the production of multicolor space photo cards by printing,.

A known method of producing multicolor space photo maps, including obtaining a black-and-white space photographic map, a cartographic original of a multicolor background thematic load and an original of a black and white stroke load, making a cartographic original of a multicolor background thematic load of raster photoforms according to the number of color inks, making

a white cosmoplane of one raster photoform for the subsequent creation of the photographic image of the Earth's surface in black, the manufacture of printed forms and the print run of multicolor photo maps

In this method, a multi-color image of a thematic load and a black-and-white photographic image of the Earth are reproduced and printed separately in 8-10 or more colors. The process of producing thematic load raster photoforms is carried out manually using dissected masks and paints, the photographic image of the Earth's surface on impressions an insufficiently high difference with large losses causes the background color of the thematic load to be loaded, and in general, the photo card does not have sufficient consistency and reliability.

The aim of the invention is to increase the sharpness, consistency and reliability of a multicolor space photo map.

The goal is achieved by using a multicolor background thematic from a cartographic original (Three color separations of photonegates are made for the blue, yellow and purple colors of the triad by separations, and the normal black with white space photomap of the earth's surface is made with an accurate gradation characteristic and contrasting grayscale photonegatives, form a multicolor space photo image of the manufacture of precast raster photoforms for the triad inks, which consist in the sequential combination of a normal photonegative with each of those color separations photonegatives, their rasterization, rasterization of a contrast photonegative and combining it with the original black and white line chart load, while the original multicolor background thematic load is made with a decrease, and during the color separation period it is increased to the scale of the space photo cards

The method is characterized by the following operations.

Known methods are used to obtain a black but white cosmophotoplan, a cartographic: ical original of a multicolor background thematic load and an original

black-and-white dashed load, then from the cartographic original of a multicolor background thematic load, by means of color separation, three color-separated photonegatives are made for the triad blue, yellow and magenta colors, and two black-and-white cosmonoplanes of the Earth’s surface are reproduced by photographing two semi-tone photonegatives: normal accurate gradation characteristic, and contrasting. The formation of multicolor cosmic photo images is produced by making precast raster photoforms for triad rasad For this purpose, a normal halftone photonegative of a black and white cosmichotoplane is sequentially combined with each of the three color separations of half-mass negatives of the thematic load with rasterization in the frame of contact copying using a contact raster, and the contrast photo-negative of a black and white cosmo photo plan is first rasterized combine with the original black and white line load card

Thus, a set of color-separated raster photos is made. Forms for four-color printing of blue, yellow, magenta and black inks, which are later used to produce printing forms and printing space photo maps. It should be noted that in the process of obtaining the original multi-color thematic load it is reduced, and during color separation it is increased to the scale of publication space photo card

The proposed method for the production of multicolor space photo maps provides reliable and implicit multi-color space photographs of the Earth's surface simultaneously with thematic cartographic load, such as landscapes, the required sharpness of space photographs with a clear elaboration in both light and dark areas (due to the formation of an image from A-X paints), the possibility of issuing multicolor space photo maps of just 4 printing inks with their printing on 4, colorful offset sheet majines in one pass, as well as the possibility of preparing for the publication and publication

METHOD FOR PRODUCING MULTI-COLOR SPACE PHOTOCARDS, including obtaining a black-and-white cosmophotomap, a cartographic original of a multicolor background thematic load and an original of black-and-white line loading, making from a cartographic original a lot of | one raster photoform for subsequent reproduction of a photographic image of the Earth's surface in black, the manufacture of printing plates and printing a circulation of multi-color photo cards, characterized in that, in order to increase the sharpness, clarity and reliability of a multi-color space photo card, three color-separated photo-negatives for blue, yellow and purple colors of the triad, with black and white, are produced from the cartographic original of the multi-color background thematic load the white cosmophotomap of the Earth’s surface is made normal — with accurate gradation characteristics — and contrasting halftone photographic negatives — they form a multicolor cosmophotomobility An example of this is the fabrication of prefabricated raster photoforms for triad paints, which consists in sequentially combining a normal photo-negative with each of the three color-separated photo-negatives, rasterizing them, rasterizing the contrast photographic negative and combining the original black and white dash card load, while the original is a multi-color thematic load made with a decrease, and during the period of color separation it is increased to the scale of the publication of a space photo card.
