Equipment
Printing Spring Festival this product,
Seemingly simple, but the production conditions are high, the most important thing is that the plate-making printing equipment is large. In terms of the 1.50m long Spring Festival, the direct working area of its plate-making printing equipment must reach 1.50m or more, and the maximum printing area of the general offset printing machine. For full opening (1.10m), it can be seen that the general offset printing machine can not produce more than 1.50m of Spring Festival couplets, which is why there are few spring couplets in the offset spring couplets that are more than 1.10m long. When using the screen printing method, in order to produce more than 1.50m meters, the Spring Festival couplets must have a large Chunlian plate-making press or a large plate-making machine.
2. Paper
Screen printing Spring Festival couplets are better printed on red paper, because the use of red paper to print the Spring Festival is easier than the use of white paper to print the Spring Festival, and the plate making costs are low.

Screen printing Spring Festival couplets are suitable for red paper with Zhu Hong machine. In the south, there is a kind of red-column joint paper in the whole year. This paper is characterized by rainproof, light-resistant, non-fading throughout the year, and the color is vermilion. After a period of sun exposure, it gradually turns into deep red, and the rain is dry and dried. Still red, the Spring Festival couplets made with this kind of paper are attached to the door, which is red all year round and the effect is very good. In the south, people generally subscribe for this Spring Festival couplet product. The Spring Festival couplets printed on ordinary red paper are unattended. This is because the rain often occurs during the Spring Festival in the South. If the paper is not good, the Spring Festival has not changed beyond the normal, it will make The Spring Festival has become very disappointing.
3. Ink
Screen printing Spring Festival inks, generally with offset resin ink, can also be used with black enamel and offset resin ink blending, another method is to use black offset ink plus varnish. The spring couplets printed with these inks are black and bright.
Auxiliary materials are: red dry oil, white dry oil, gasoline, thinner, banana water, acetone, xylene and the like. Gold ink can be offset with gold ink, or gold powder can be used to adjust xylene and varnish. The diluent can be used with gasoline. The concentration is preferably a dry mesh.

For the rubber compound, the vinyl chloride paste for the rubber compound, the aluminum alloy (gold) for the hot stamping material, and the hot stamping equipment are the hot stamping machine or the electric iron.
5. Workshop
The working room is at least 20m2, and the wall is covered with a row of iron wires with a spacing of 33cm for hanging the Spring Festival couplets. The larger the work area, the higher the production efficiency.
1. Red paper screen printing Spring Festival
Place the cut red paper on the glass, open the copy exposure lamp, align the red paper with the original position, fix the red paper positioning mark with double-sided tape, and then place the prepared screen on the red paper. , align the position and clamp the screen to the net clamp. Turn off the light, put down the screen, place the adjusted gold ink on one end of the screen, scrape the scraper from the end to the other end, lift the screen and check the printing effect. When printing, each piece should be aligned to ensure that the text is printed in the stroke just when the black text is printed. Two people need to work at the same time when printing. After the first golden dry, reprint black text in the same way as the gold pattern. Pay attention to the registration when printing.
In printing, the most common fault is that the ink is extruded from the bottom of the net. The reason is that the screen is stretched loose, causing a gap between the net and the paper, and the other reason is that the ink is too thin, especially when printing This type of problem is most likely to occur. In screen printing, dry mesh is also one of the most prone problems. In summer, the temperature is high, the ink is dry quickly, and the net is easy to dry. At this time, 783 slow dry water can be added to the ink. If there is no 783 slow dry water, add some diesel oil. Low temperature, slow drying, need to add red dry oil or white dry oil in the ink, you can also add acetone, xylene, banana water, thinner, gasoline and so on. The room temperature must be kept above 15 °C.
