Embodiment 1

[0025] The method of double-sided overprinting color mark of the present invention includes the following steps:

[0026] 1) Select the packaging film, and set up a blank space on the packaging film's imposition for placing the same color mark as the packaging film printing color;

[0027] 2) Make the original manuscript in the computer, and add the four color codes of front and back to the blank space of the paper in the imposition plate of the product;

[0028] 3) Divide all the printing colors in the packaging film into several color groups, and make the color mark on the printing plate roller corresponding to the printing color of the color group;

[0029] 4) Adjacent color codes in the color codes corresponding to the unified color group have the same length from the edge of the packaging film;

[0030] 5) Start the drying system;

[0031] 6) The printing plate rollers with the color codes of various colors are installed on the printing units of the printing press;

[0032] 7) Add th...

Abstract

The invention discloses a double-side color code overprinting method. The double-side color code overprinting method comprises the following steps that a packaging membrane is selected, and paper blanks used for carrying color codes with the number the same as the number of printing colors of the packaging membrane are arranged on an imposition of the packaging membrane; an original pattern is made in a computer, four front and back color codes are added to the paper blanks in a core of the imposition of the product; the distances, to the edges of the packaging membrane, of the adjacent color codes in the color codes corresponding to unified color cells are the same; a drying system is started; printing plate rollers with the color codes of all colors made are installed on printing units of a printing machine; the pressure of printing rollers of the printing units is regulated; printing tension needed by the printing machine is regulated; various parameters needed in printing are input into a display screen on the printing machine, and automatic overprinting tracking is achieved. According to the scheme, overprinting paper is saved on the premise of not influencing any overprinting quality; besides, operation is simple, no extra cost is increased, and meanwhile double-side overprinting can be achieved on the packaging membrane.

Description

Technical field [0001] The invention relates to a method for overprinting a color code, in particular to a method for overprinting a color code on both sides. Background technique [0002] Packaging and printing are of great significance in beautifying life, protecting commodities, and enhancing the competitiveness of commodities in the market. In terms of packaging, the role of packaging and printing is emphasized. In recent years, the country has paid more and more attention to the packaging industry, packaging technology transformation and equipment update are progressing rapidly, and the high-speed printing of automatic color register systems has been increasingly used. At present, most of the high-speed gravure printing presses with automatic color registering on the market are foreign products. The printing speed and degree of automation are high, but the price is quite expensive. [0003] Based on this research, a method of double-sided overprinting color code was develope...
