Embodiment 1

[0034] Embodiment 1: A kind of " red golden dragon " product that adopts a kind of improved gravure printing machine of the present invention to be used for printing the method for printing cigarette package snowflake picture, prints according to the following steps:

[0035] (1) "60 line 55u" laser engraving is used to make gravure; when engraving, if there is a net pattern on the paper, the angle of the concave hole should be consistent with the net pattern on the paper, so as to avoid faint moiré patterns and affect the snowflake effect;

[0036] (2) UV ink is used for printing; coarse snowflake (Shensaier SRA-2000HH7) and fine snowflake (Shensaier SRA-2000YZ3) inks are used, and the ratio is 3:2. Xaar ABR-020C), the ratio of ink to thinner is 15:1, too much thinner will affect the snowflake effect.

[0037] (3), UV patterning lamp 1 chooses metal halide UV lamp, power 4500W; make UV ink detonate ink under the irradiation of UV patterning lamp after printing, can form delic...

Abstract

The invention provides a method for printing cigarette packet snowflake patterns by using an improved intaglio printing press and relates to the improvement of a single-color intaglio printing press. A UV (ultraviolet) line forming lamp tube is arranged in front of a tooth row between paper delivery chains of the intaglio printing press, the distance between the UV line forming lamp tube and paper is between 12cm and 15cm, a group of UV optical curing lamp tubes are arranged 1.5-1.8m ahead of the UV line forming lamp tube, an air pump is arranged between a line forming lamp tube and optical curing lamp tubes and a paper guide tray is arranged on paper supporting steel bars between the paper delivery chains. The method comprises the following steps of: making an intaglio by using a '60 line 55u' laser engraving process; performing UV snowflake ink printing; detonating ink under the irradiation of the line forming lamp to form fine and smooth creases; and performing high-power drying and curing by using a group of high-temperature UV optical curing lamp tubes; printing cigarette packet snowflake patterns with an outstanding effect at the speed of 4100-4300 pieces of paper per hour by using the improved intaglio printing press. The method provided by the invention is simple, the cost of the application of the improved intaglio printing press for printing is low and the printing speed is higher than twice that of a screen printing machine.

Description

technical field [0001] The invention relates to a method for printing snowflake patterns on cigarette packs by an improved gravure printing machine. Background technique [0002] With the continuous development of printing technology and consumers' higher and higher aesthetic requirements for packaging, the grade requirements for various promotional printed materials and packaging products are getting higher and higher. Because screen printing can express various special ink effects, the decorative graphics of packaging products have been developed by leaps and bounds in recent years. Among them, the silk screen snowflake (freezing point) effect is a good example. [0003] The snowflake effect of silk screen printing is a kind of fine sandy feeling and hand feeling formed on the surface of the printed product after ink silk screen printing on gold cardboard, silver cardboard, laser cardboard, PVC and other substrates is wrinkled by ultraviolet light and cured by UV light. ...
