Demystifying the hand-rolling Spring Festival printing technology and production technology

1. The production of the stencil frame should be based on the printed paper size of the scrolls to determine the size of the stencil frame. The inside diameter of the stencil frame should be larger than the size of the stencil paper by 5cm. You can use the 3cm × 5cm wood, in the stencil box. Plane by the inner diameter of 1cm-1.5cm scraped deep 0. cm slot, according to the width and depth of the slot do a good job wooden bar.
2. Stretch the nylon screen according to the size of the frame, wet it with water, nail the circumference of the nylon screen with a distance of about 2cm to the side of the frame, and then use the small The nails will be pressed into the slot on the nylon mesh screen, and then the nails will be rinsed with water and dried.
3, scraping photosensitive adhesive This process must be carried out in the dark room, the lighting can be red light or candle XS-1 diazo photosensitive glue into the lower part of the screen plane, with plexiglass ruler up scraping. The film shall be evenly distributed and covered with a mesh surface. If the gravure surface of the screen has penetration of glue, please scrape it flat. The purpose is to thin the film and prevail. The mesh is sealed and dried naturally.
4. The black and white draft of the black and white draft is the most critical process of the plate making process. It not only relates to the success or failure of the platemaking, but also directly affects the quality of the product. In the absence of the basis of calligraphy, it is free to find some exquisite scrolls and patterns, and also It can be typed on a computer, and then placed on the desktop. A glass with the same outer diameter as the outer diameter of the frame and a clean glass is used to describe the shape of the ink. The lines of the character must be completely black and the light must be traced. Check, if any leaks are repaired in time, if there is irregularity in the character-based lines during the drawing, after the ink is dry, the excess part can be scraped off with the tip of the knife, and the draft can be revised. If the fine pattern is depicted, the hard pen can be selected for drawing. The black ink is carried out, and then can be combined with glass black and white as needed, without affecting the plate making effect.
5, exposure This process must be carried out in the dark room, take a 0.5cm thick and above the plate and the frame must be thicker than the frame plane 2cm thick sponge, first put the sponge into the concave surface of the screen, and then put the plywood on the sponge Above, and then turned over, that is, plywood down, and the plane of the screen is upward, and then the painted black and white manuscript with the ink side down, the center smoothly on the plane of the screen, all around with a clip The following plywood is clamped between the black and white glass of the glass to prevent lateral runaway so as to avoid the lack of plate making and failure. After it is arranged, it can be taken outside for exposure. The exposure time is generally between 1 minute and 3 minutes. Depending on the degree of light, the time of strong light is short, the time of weak light is long, dark weather is not suitable for exposure, and indoor lighting can also be used for exposure. Four 40W fluorescent lamps or 200W bulbs are evenly distributed on the top of the screen. If the fluorescent lamp is 30cm away from the screen, the lamp needs to be separated from the screen by 50cm. The exposure time is 30 minutes. After the exposure is over, it should be immediately The screen back to the dark room to remove the black and white drafts, sponges, plywood, speed 60 degrees with natural water flush the front and back sides of the screen, usually rinse about 3 minutes to the screen on the basis of the word, pattern clear. After drying, the platemaking process is completed.
Second, the printing process First to do a printing scraper, take a length of 26 cm, 13 cm wide and two equal-size Polaroid plate, and then take a piece of 26cm long, 14.5cm wide, 0.5cm thick rubber plate, with two pieces of treasure Liban sandwiches the rubber plate in the middle and aligns it on three sides. On the other side, the rubber plate is 1.5 cm taller than the Polaroid plate. The “sticky” adhesive is used to glue the three together. In addition, the size of the scraper can be lengthened or shortened according to the width dimension of the printing screen. It is also possible to use plexiglass rulers instead of glue scrapers to complete the printing.
Place the finished screen plate with the concave surface facing up and position the hinge on the workbench board, take 30 sheets of cut red paper into the bottom of the screen, and align with the screen base pattern of the screen to find the size of the four peripherals. , Stir the paint evenly after fully mixing, repeatedly scrape from right to left, each scrape to one side, that is to say, once the city is finished printing, the screen will be opened, the printed product will be removed, and the printed product will be sorted by analogy. Use even force. Immediately after each printing, wipe the screen with a towel and dip oil to prepare for the next use.
Third, the sticky gold process chooses a surface flat pressure worktable, above and then spread a slightly larger than the size of the printed spring 0.5cm thick and very smooth and smooth quality rubber sheet. The electro-aluminum hot stamping foil is cut according to the size of the printed spring couplets, and after printing for about 20 minutes, the electro-aluminum hot stamping foil can be affixed to the printed word-base pattern parts of the Spring scrolls. Use a towel to strongly press the word base and pattern parts, and confirm that 24 hours after the compaction is correct—after 36 hours, you can remove the affixed aluminum foil hot stamping foil.
