Description

Ink fountain protection device for four-color printing machine

Technical Field

The invention relates to the technical field of four-color printing machines, in particular to an ink fountain protecting device for a four-color printing machine.

Background

The four-color printing press is a printing press using a lithographic printing method for realizing map copying by using four inks of black, medium blue, brown and green. The printing was performed with the subtractive primary colors (yellow, magenta, cyan) and black. If a printing process for reproducing the original color is performed using inks of colors other than four colors of yellow, magenta, cyan, and black, it should not be referred to as "four-color printing" but as "spot color printing" or "dot color printing". A lithographic printing method for full-color reproduction by subtractive color mixing of three primary colors of red, yellow and blue and black colorants (inks or dyes). The offset printing method for copying the map by using four kinds of black, medium blue, brown and green ink is a common printing method for Chinese large-scale topographic maps and has a uniform color scale. The color of each element is defined as: the ground feature, the figure outline finishing and the mark are black; the water line, the single line and the mark thereof are blue, and the water general dyeing part is a medium blue lattice point with 100 lines/inch of 15 percent; contour lines, special landform symbols, notations thereof and brown for general dyeing inside roads; forest linedyeing was carried out with a green grid or dot of 100 lines/inch.
