The first wood timber use has a long history. Historically have been the mainstream of the materials used, the deformation of woodiness material is widely used in gardens, zoos, parks and other scenic spots. Give a person the feeling of natural kind, the second stone stone material as well as the use of wood has a long history, it is not susceptible to damage to the natural conditions, long service life. Zui big shortcoming is the material itself is too heavy, is not conducive to the processing, structure is considered. But it and wood texture of effect is very good, unique style, culture flavour, is does not take the place of the other materials. Common stone has bluestone, granite, marble, etc. The traditional regression. Downside is that the cost is higher, the ordinary wood while the cost is low, but easily affected by natural factors appear deformation, cracking and other problems. Often material with walnut, rogues, rosewood, etc. The third week of aluminium alloy metal materials: aluminium alloy identification in modern marking system refers to for aluminum alloy material, modular design of the structure of the logo, facilitate unified and standardized. Its advantage is itself quality good, slow oxidation; Light weight, fashionable appearance clean and tidy; Install the light; Reasonable structure design makes it easier to replace, plate thickness, good leveling; Color adhesion, strong and durable not easy discoloration, cost is low. Screen printing label factory introduced silk-screen label technology standard is what? Screen printing plate production process, the decisive role is the silk screen printing and printing substrates before processing technology and key points of printing and screen printing ink. One, the screen printing plate: 1, paint film engraving method: printing plate is one of the manual plate making method, is relatively simple. Can be printed normally not too delicate monochrome pattern and text. ( 1) Spray system generated film paper: use tracing paper paste stick on flat boards, with the combination brush pen 1 rubber water ( Volume ratio) 1 set, gasoline, evenly coated on paper, dry spray soft varnish after 35 times, each time after spraying, with 40 ~ 50 degrees in oven drying, spray paint film thickness to 5 ~ 6 millimeter advisable, coating should be bright, smooth, no bubbles, no stain. ( 2) Carving graphics: stick film paper on graphics, press with kedao, compasses knife, ruler graphic carvings, gently remove paint film. ( 3) Quote: after carving graphics, can the past do silk screen frame on a quote. Method is to put the carved film under the net frame clamp, use cotton with a little thinner in the above after wipe gently, until paint film and screen glued down. Off tracing paper to dry after a few minutes away. If the paper is not gone completely, usable cotton touch water wipe. Blank part with lacquer coating layer, screen mesh plug. Printing after dry. 2, carbon paper plate burning method: is a kind of relatively simple manual plate making method. ( 1) Sensitive paper cutting, paper is a kind of mixture thicker coating and oxygen barium base paper made of carbon paper, according to the size of the graphics lay aside. ( 2) Sensitization: in 500 and 20 g in the preparation of ammonium dichromate solution soak for 3-5 minutes, remove carbon paper, the water distribution. ( 3) Exposure: stick carbon paper flat in a clean glass, film, coating on the male figure polyester film negatives, using printing-down machine exposure, exposure time 8 to 12 minutes. ( 4) Development: after exposure in 40 ~ 50 degrees warm water soak for a few minutes, the film and Yang chart with zinc oxide base paper from nature, carefully developed with warm water to form the text clear so far. ( 5) Quote: the system to put the good guy good screen net box below the first, on the screen covered with several layers of newspapers, the pressure on the glass plate, with the weight of 1-2 kg/cm2, the film and screen stick firmly, remove the weight and the newspaper, use the electric stove dry film, then remove the base paper, film graphics to the screen on. Qualified carefully check whether there is any defect on the graphics, the graphics on the screen around the coated with a layer of nitrocellulose enamel protection, the printing plate in a plate, and be ready to print. Scope of application of this process method is the same as the film engraving method. 3, photographic plate making method: screen printing signs printed CARDS used in the precision demand is higher, generally USES the advanced direct, indirect, direct between three kinds of photographic plate method.
