Detailed Product Description: | Chengdu the Yonghe photosensitive Materials Co., Ltd. Manager: Liu Yue Cheng telephone: 15682017147 film is silver halide photographic film, also called the film. Made by the PC / PP / PET / PVC material. Now generally refers to the film, the backsheet can also refer to the printing plate. Film are black, the corners of the film is generally have an English symbol is the number of films, indicated that the film is C, M, Y, K which a cmyk of one (or tertiary color number) , this film what color output, if not, you can look at the linked network point of view, to identify what color. Besides watching the network density is normal, the color bar or a is to see CMYK, color bar in the lower left corner of C, the color bar in the upper left corner is M, in the upper right corner is Y, in the lower right corner is K, according to the color bar printing know CMYK. In other words, in order to facilitate the inspection of film developing concentration Films angle color number. As for the number of colors printed while each film piece cable set. Outlets in the film is to tell you, "There is a color of this degree of, for example, the general text version, there is only one black, a film version of the child, if you printed with red ink, the print-out is The Scarlet Letter. A film sheet to represent a color, printing color, at least four film sheet, representing the C, M, Y and K four color! The four spot color, spot color film output in a separate file into K Edition. The next color CMYK not indicate the specific values, but a control test film out of compliance with the requirements. Some habits are unfinished moldings (crop marks, registration lines), then solid color marked on each version of each version of the name. For example, marked on the C, M, Y, K, specifically silver, respectively fill Lan, red, yellow, black and spot color version on spot color, so that out of the film has a logo and particularly intuitive. The color patches size 10 * 5mm, the marked paper color CMYK English letters, blocks of color and color name of the one-to-one correspondence. Proofing workers can see film corner. Generally speaking, the the film network point of view are fixed, like the yellow version of the network angle is 90 degrees. There are exceptions, if the image of the yellow expression is concentrated in the 90-degree range, then the yellow can not use 90 cents or traces of hanging on too obvious!! Usual sense, a color, you should make a color bar sequentially to check that the color of a film process, the respective density ladder Shaizhi situation is very clear, generally four color bars, and arranged very neat. Most of the color comes from the combination of these four colors have come, each film are black except that they represent different colors C, M, Y, K, take a look at the proportion of know, and then by printing four-color ink. Edit this section the film imaging principle Each film (color film) comprises two basic components: a monolayer or multilayer photosensitive emulsion layer, a photosensitive emulsion layer of the support - film base. The emulsions are made by the light-sensitive fine particles suspended in a gelatin medium. Gelatin and some food in the film are similar to gelatin. The photosensitive material is suspended in the gelatin silver halide grains. The particles are so fine, can be observed only in the high-powered microscope. 1 in2 usual photographic film emulsion, the content of the silver halide crystals is about $ 40 billion as much as the silver halide crystals having Upon exposure of the characteristics of its structure changes. The this chemical properties change mechanism is not important for us, the end effect of the change is the most important. How will this change it? When you're shooting, the light shines through the lens of the camera on the film emulsion layer when the light reaches the silver halide crystals, these crystals undergoing structural changes, with neighboring silver halide crystals coalesce together by light irradiation. Clumps formed by coalescence of the silver halide crystals is still an extremely fine. The more the amount of light received by the emulsion layer, and there are more crystals coalesce, the light amount is less, the change of the crystal, and coalescence less. No light fell on the emulsions will be no changes in the crystal, and coalescence. This means that microscopic fields of different intensity of the impinging light on the film, the film emulsion layer have a different number of crystal structure change occurs and the mutual coalescence of the film has been exposed, immediately generate the latent image - the image of an invisible. The film must be developed to do gymnastics in order to make the latent image into a visible solid image. When developing a film, the silver halide crystal structure has changed will be converted to black metallic silver particles agglomerate, thereby generating an image - negative image. No photosensitive film, that is no structural change occurs crystals i.e. a technique called fixer chemicals washed away, so that these portions to render the light gray or transparent. The result is a negative image on the dark (thick) portion is exposure more parts; bright (thin) is exposed areas; transparent portion is not subject to the portion irradiated with light. This is a black and white film to record images of the basic process. The color film has three photosensitive emulsion layers, respectively containing different organic compound be able to generate a dye in these emulsion layers, called color coupler (coupler). Which are themselves colorless, but the color developing oxides coupled with a color developer a colored dye. The negative film, the coupling agent is contained in the upper blind color emulsion is formed in the color developing yellow, the middle forming a magenta, a lower layer forming cyan, which is obtained after washing the color film. By enlargements or enlarged then the image projected onto photographic paper or reversal film reversal rinse the yellow film upper layer into its complementary color blue, the middle layer turns green, the lower turns red, we get the natural state photos or transparent color reversal film. This is the basic process of color film to record images. Editing to the performance of this paragraph, the film-PC sheet: has excellent physical and mechanical properties,?? 2: excellent impact resistance, tensile strength, flexural strength, high compressive strength; creep resistance, dimensional stability. 3: having a good heat resistance up to 125 ° C and low temperature resistance of minus 45 degrees within a wide range of temperatures, having stable mechanical properties, dimensional stability, electrical properties and flame retardancy, can be -60 to 120 ° C the long-term use; no obvious melting point, in 220-230 ℃ molten state; due to the rigidity of the molecular chain, the viscosity of the resin melt 4: The water absorption is small, shrinkage is small, and high dimensional accuracy, good dimensional stability, membrane permeability ; is a self-extinguishing material; 5: Light stability, but not resistant to UV light, weathering good; oil, acid, intolerance strong bases, oxidizing acids and amines, ketones, soluble in chlorinated hydrocarbons and aromatic family of solvents in the water for a long time could easily cause hydrolysis and cracking disadvantage is prone to stress cracking due to fatigue strength, solvent resistance, abrasion resistance poor. View disk edit this paragraph the film-PC chip application instrumentation, piping systems, insurance, glass, writing pad, slide projection equipment parts, widely used in the field of machinery, electronics, automotive, construction, household items, and are expanding rapidly to aviation, many high-tech fields, such as aerospace, computer, CD-ROM, optical fiber Hanabusa, channel lighting, gardens, entertainment venues singular decorative and rest places Gallery kiosks, telephone booths, advertising signs, advertising light boxes show the layout of the exhibition, wall, roof, screens high-grade interior decoration material, highway and urban elevated road noise barriers, agricultural greenhouse and breeding shed, the sound barrier projects, canopy lighting, building materials industry, industrial products, anti-theft devices, LED electronic display bezel, resin board, basketball guard PC series of the front windshield of the basketball board, aviation transparent container, motorcycles, airplanes, trains, ships, cars, steamboats, submarines, glass military and police shields, electric vehicle sun visor, Chengdu Yonghe photosensitive materials manager: Liu Yue Cheng Tel: 15682017147 |
