Although the Spring Festival couplets as a commodity are very seasonal, the social requirements are relatively stable. Print Spring Festival couplets by screen printing method is relatively easy to grasp technically, and can make full use of existing production conditions and achieve better economic benefits.
In the past, the production of the Spring Festival was basically based on offset printing, supplemented by manual writing. In recent years, due to the popularization and promotion of screen printing technology, screen printing Spring Festival couplets have begun to appear in some places. From the production process point of view, screen printing Spring Festival couplets and offset spring couplets, hand-written Spring Festival couplets have their own advantages.
Screen printing Spring Festival process flow
(1) The most basic requirements for a good Spring Festival couplet product are: beautiful fonts, novel content, beautifully printed, and excellent paper. The four points are whether the Spring Festival couples can achieve better results in market sales. The key to benefit. Therefore, the words used in Spring Festival couplets must be beautifully written and have profound calligraphy skills.
The preparation of text Yang artwork:
1 Select from the Spring Festival couplet books a wide range of applications, the novelty of auspicious Spring Festival couplets, enter it into the computer, select the fonts on the computer such as: Shushu, Xingkai, Lishu, Weibei and other fonts. With a laser printer, the imposition can be used for printing.
2 Spring Festival of Spring Festival of the Spring Festival of Spring Festival, which was written from the printed printing couplets for sale, was copied onto a white paper by a copying machine, and it could be enlarged or reduced as required during copying. In general, the red part of the Spring Festival scrolls would become black or gray, and it would be printed in white. Coat white, and then copy again, you can get a clear text, this text is soaked in wax, it becomes a transparent text, can be used as a positive version.
3 Calligraphers or calligraphers are required to write Spring Festival couplets. They are best written directly on transparent glass paper. If they are written on rice paper or plain white paper, they can be used for making plates after being immersed in wax.
If the text of the pattern is the bone of the Spring Festival couplets, then the pattern is the meat of the Spring Festival couplets. There are bones and flesh that can constitute a perfect artwork. In the Spring Festival couplets, the pattern can play a decorative role, and the meaning of the words to be expressed in the scrolls can be expressed indirectly through the patterns. From an artistic point of view, the pattern can add a layer to the Spring Festival couplet's picture, and it is visually unobtrusive and dull.
Pattern preparation:
1 Copying method This method is mainly to find some of the blank picture book to copy it, and the copy will be re-waxed, which can be used for printing after the imposition. The contents can be selected from landscape paintings, figure paintings, flowers, animals, etc. The pattern draft made by this method is of high quality and low cost.
2 Manual drawing The advantage of drawing by hand is that it can avoid the difficulty of making an imposition caused by the inconsistency of the size of the length of the photocopy and the length of the scroll. The key to hand-painting is the high level of requirements of the painter. The outer stroke of the text must be drawn by hand.
3 electronic color design A color pattern consistent with the size of the Spring Festival couplets, after the separation by the electronic color separation machine can be obtained yellow, product, green, black four-color negatives, using this four-color film, four-color printing, You can print color scrolls.
(b) Plate Making
Combine the pattern draft with the transparent draft of the stroke, align it with the rule line, place it on the plate making machine, open the exposure lamp, and coincide with the register line on the plate making machine glass, stick it with double-sided tape or transparent adhesive tape, and close it. Remove the exposure lamp; apply the sensitized adhesive under the red light of the dark room, dry it and place the screen on the plate making machine, cover it with a black paper, put the sponge foam board on the paper and press the heavy object, such as brick, on the paper; At this time adjust the timer, press the print button, start the exposure, the time is 5 minutes, the time to the automatic shutdown, remove the screen, wet wash with water; turn on the lights, check the screen, continue to rush Until clear. The same applies to the text version. After the pattern plate is dried, seal the part of the pattern that needs to be printed in the text stroke with a screen-sealing glue or a photoresist, and after drying, seal the periphery of the screen plate and wait.
(III) Printing Working Conditions
1 Equipment Printing Spring Festival couplets This product seems to be simple, but the production conditions are demanding, the most critical is the plate printing equipment to be large, in terms of Spring Festival of 150m long, its direct working area of ​​plate printing equipment must reach 1 50m Above, the maximum printing area of ​​a typical offset press is fully opened (1 10m). It can be seen that general offset printing presses cannot produce spring couplets of more than 150m. This is the reason why there are few Spring Festival couplets over the length of more than 1 10m. When using the screen printing method to produce a Spring Festival couplet of more than 150m2, a large Spring Plate printing machine or a large plate-making machine is required.
2 Paper screen printing Spring Festival couplets are preferably printed with red paper, because the printing of Spring Festival with red paper is simpler than printing with white paper, and the plate making cost is low. There are many varieties of red paper, from the color points are red paper, red paper, from the production process, organic brush red paper, hand-painted red paper. Screen-printing Spring Festival couplets with Zhu Hong machine brush red paper is appropriate. In the south, there is a year-round red spring lining paper, which is characterized by rain, light, and not faded throughout the year. The color is vermilion. After a period of sun exposure, it gradually turns dark red, and it dries out after rain. Still red, the Spring Festival couplets produced on this kind of paper are attached to the gates and are red all year round. The effect is very good. In the South, people generally subscribe to this Spring Festival couplet product. Spring scrolls printed on plain red paper are not used. This is the reason why it often rains during the Spring Festival in the South. If the paper is not good enough, the Spring Festival couplets have become unrecognizable. The Spring Festival has become very disappointing.
3 Ink screen printing ink in combination with spring, generally with offset resin ink, black enamel can also be used with offset resin ink blending, another method is to use black offset ink plus varnish. Spring scrolls printed with these inks are black and bright. The auxiliary materials are: red dry oil, white dry oil, gasoline, thinner, banana water, acetone, xylene and so on. Gold ink can be used offset gold ink, gold powder can also be adjusted xylene, plus varnish. Diluent available gasoline. Concentration is suitable for the network.
4 Bronzing materials for the use of vinyl chloride paste, electro-aluminum (gold) for hot stamping materials, and hot stamping equipment are hot stamping machines or irons.
5 At least 20m2 workrooms are in the workroom. A row of iron wires is hung on the wall with a spacing of 33cm to hang Chunlian. The larger the workshop area, the higher the production efficiency.
(d) Printing
1 Red paper screen printing couplets put the cut red paper on the glass, open the copy exposure lamp, align the position of the red paper and the original, fix the red paper positioning mark with double-sided adhesive, and then fix it. Place the screen on red paper, align it, and clamp the screen on the folder. Turn off the light, put down the screen, put the transferred gold ink on the end of the screen, scrape from the end to the other end, lift the screen, and check the printing effect. When printing, each piece must be aligned to ensure that the text is printed exactly within the stroke. Two people work at the same time when printing. After the first golden dry, print the black text again. The method is the same as when printing the gold pattern. Pay attention to the registration when printing.
In printing, the most prone to failure is the extrusion of ink from the underside of the web. The reasons are as follows. First, the screen is stretched loose, causing gaps between the web and the paper. The other reason is that the ink is too thin, especially when the text is printed. The most prone to such problems. In screen printing, dry web is also one of the problems that are easy to occur. In summer, the temperature is high, the ink is dry quickly, and the net is dry. At this time, 783 slow-drying water can be added to the ink, and diesel can be added when there is no 783 slow-drying water. The temperature is low, and the drying is slow. In the ink, red dry oil or dry white oil is added, and acetone, xylene, banana water, thinner, and gasoline can also be added. The room temperature must be maintained above 15°C.
In printing, sometimes the ink dries too slowly. For example, when the indoor iron wire is full, the ink that was printed at the beginning is still not dry and cannot be retracted, which will affect the continued printing. If the ink dries quickly, it will dry the web and increase the number of wiping. To solve this problem, we must first ensure that the net is not dry during the first period of time after the first sheet is printed, the second sheet is placed, and then the screen is released. The ink is printed on the paper again. In this way, the ink concentration should be suitable without extruding from the bottom. Another point is that when the indoor wire is full, the Spring Festival of the first wire is completely dry. At this time, the Spring Festival couplets on this line can be put away and printing can continue. To achieve the above two points, we must be familiar with many factors such as ink performance, thinner characteristics, seasonal temperature, etc., and work out practical experience in the work. Only in this way can we print good products, and the work efficiency will be greatly improved.
2 Red Paper Stamping Spring Festival Bronzing Spring Festival's printing material is vinyl chloride paste. This paste must be purchased at the chemical reagent store or purchased at the plastics factory. If this slurry cannot be purchased, perchloroethylene resin can be used to make vinyl chloride paste with xylene and cyclohexanone. The formula is as follows: Perchloroethylene resin 100g Xylene 50mL Cyclohexanone 350mL The perchloroethylene resin is added to the xylene cyclohexanone mixture to dissolve, which results in a perchloroethylene slurry.
In printing, use vinyl chloride paste instead of ink, and print it on red paper. Before it is nearly dry, put it on electric aluminum. Use hot stamping machine or electric iron to heat and press. The temperature should not be too high. Then tear off the excess anodized aluminum, which is a bronzing effect.
Screen printing Spring Festival production efficiency is very high, in general, when all kinds of preparation work has been completed, starting from the time of printing, two people a group can be printed every day for more than 1 500m spring couplets 1000 pay, if you produce dozens of Spring Festival With more than 3,000 copies per stamp, one month is enough to complete, so the sales problem is very prominent. The sales approach should be centered on wholesale, and the advertising campaign should be strengthened. In general, the New Year's Eve once passed and the Spring Festival franchise wholesale peak has passed. At this time, the remaining Spring Festival franchise can set up sales in the market.
For a small screen printing factory, printing only one species of Chunlian is not enough. In order to make full use of production conditions, Indian Spring Alliance can be arranged from September to October every year. Other four-color indoor murals and curtains can be printed at other times. Advertising umbrellas, travel hats, flags, test papers, review questions, banners, glass paintings, woven bags, cartons, stickers, plastic bags, vests, etc. This will keep your production equipment in operation.
