1. Production of plate frame: The size of plate frame should be determined according to the paper-cut size of printed Spring Festival couplets. The inner diameter of the plate frame should be 5 cm larger than the paper-cut size, and the wood square of 3 cm× 5 cm can be selected. According to the width and depth of the groove, scrape a groove with a depth of 0.5 cm on a plane near the inner diameter 1 cm- 1.5 cm of the plate frame.
2. Pull the net: cut the nylon net according to the size of the board frame, soak it in clear water, nail the periphery of the nylon net to the side of the board frame at a distance of about 2 cm, then press the wooden strips on the nylon net with small nails and nail them into the wire slot, then rinse the nailed net with clear water and dry it.
3. Scraping photosensitive glue: This process must be carried out in a dark room. When lighting, a proper amount of XS- 1 diazo photosensitive glue can be poured on the lower side of the screen with a red light or candle, and leveled with an plexiglass triangular ruler. Ensure that the adhesive film is evenly distributed and covers the screen surface. If the longitudinal scraping is uneven, it can be scraped horizontally. If there is glue seepage on the concave surface of the screen, please scrape it flat, subject to the thin and flat film. The purpose is to seal the mesh and dry it naturally.
4. Drawing black-and-white manuscript: Black-and-white manuscript is the most critical process of plate making, which not only affects the success or failure of plate making, but also directly affects the quality of products. What's the matter with you? Lai Muhao? Bajifu? Is the Ministry of Magic in danger? Hey? What is next to you? What's the matter with you? What's the danger of deleting a bad mystery? Food and rice? Does Nanxun have jiaozi with Ciba bean paste? Month? What happened? What is new ┑ ┑? Hey? What are the disadvantages? What's the matter with you? What happened? What's the point? Okay？ Hey? Maid? Where's Gan He? Shang was strangled and accepted the Han school? Slow screen? Poison? What about argon? What about a new man?
5. exposure. This process must be carried out in a dark room. Take a sponge, the thickness is greater than 0.5 cm, which is equal to the inner diameter of the plate frame, and it must be more than 2 cm thicker than the plane of the plate frame. First put the sponge on the concave surface of the mesh plate, then put the splint on the sponge, and then turn it over, that is, the splint is facing down and the plane of the mesh plate is facing up. Then, put the painted black-and-white manuscript, with the ink face down, on the middle screen plane smoothly. Clamp the lower splint and the black-and-white glass manuscript on it to prevent the horizontal light from escaping, so as to avoid the loss and failure of plate making. After it is arranged, it can be exposed to the outside. The exposure time is generally 1 min -3 minutes, depending on the light intensity. The light intensity is short and long, which is not suitable for cloudy exposure. Indoor lighting can also be used for exposure. Four 40W fluorescent lamps or four 200W light bulbs are evenly distributed above the screen. If the height of the fluorescent lamp is 30 cm away from the screen, the bulb needs to be 50 cm away from the screen and the exposure time is 30 minutes. Immediately after exposure, take the screen back to the darkroom, remove the black-and-white manuscript, sponge and splint, and naturally wash the front and back sides of the screen with 60-degree warm water. Generally, it takes about 3 minutes to wash the fonts on the screen. After drying, the plate-making process is all over.
Second, the printing process
First, make a scraper for printing. Take two Polaroid boards with the same size, 26 cm long and 13 cm wide, and then take a rubber board with a length of 26 cm, a width of 14.5 cm and a thickness of 0.5 cm. Clamp the rubber board with two polaroids and align the three sides. The other rubber board is1.5cm higher than the Polaroid board. In addition, the size of the scraper can be lengthened or shortened according to the width of the printing screen. You can also use plexiglass triangle ruler instead of rubber scraper to complete the printing needs.
Place the prepared screen with the concave surface facing up on the workbench with hinges, take about 30 cut red papers and put them under the screen, aim at the font pattern of the screen, and find out the surrounding dimensions. After fully stirring the grease ready mixed paint, scrape it repeatedly from right to left, and print it once every time it is scraped to one side, that is, lift the screen and take out the printed matter, etc., and scrape it evenly. After each printing, you should immediately scrub the screen with a towel soaked in gas oil for the next use.
Third, the gold process
Choose a workbench with a flat and pressure-resistant surface, and then spread a rubber plate with a thickness slightly larger than the printed Spring Festival couplets by 0.5 cm, which is very flat and smooth and of high quality. Cut the electrochemical aluminum foil according to the size of printed Spring Festival couplets, let the printed Spring Festival couplets cool for about 20 minutes, and then stick the electrochemical aluminum foil on the printed Spring Festival couplets. Then use a towel to forcefully compact the font and pattern parts, and take off the pasted anodized foil 24-36 hours after confirming that the compaction is correct.
