什么是凹印什么是柔印（What is gravure printing What is flexo printing） 什么是凹印什么是柔印(What is gravure printing What is flexo printing) Excuse me, what is the gravure? What is the flexo? Does the gravure and flexography until the finished product from computer plate. There are several steps is different from the offset? Such as the need to offset the film - print -- put on printing machine printing. Then the gravure and flexography? The offset and what is the difference? Why would they? The following [br][br]-=-=-=- by seagullan in December 2007 09, 09:17pm added -=-=-=- Also, why Illustrator software into the picture, the documents sent to others, others sometimes have sometimes not open picture picture.? Why are the same just the document to each other, are not connected graph, why sometimes file open connection diagram, sometimes not open the connection diagram? Excuse me, what is the gravure? What is the flexo? Offset lithography is a very simple, means of speaking that is offset rubber (Pib) will plate transfer to the substrate of printing, it is also the existence of Pib, named after the printing mode. The blanket has played an irreplaceable role in the printing process, such as: it can make up for a good substrate surface is not flat, so that the full transfer of ink, it can reduce the plate of water (see water in the role in printing) to the substrate transfer etc.. The above is only a general concept, we usually say that now the offset may be more narrow in scope, namely the three roller (printing, lithographic printing, embossing blanket), in the south of our country to the printing mode called offset printing. In the China offset is an absolute dominance of the printing, printing speed, printing quality is relatively stable, short cycle of the printing books, newspapers, and many other advantages, and a considerable part of the commercial printing in the printing. The mention of printing, people immediately think of the offset, Heidelberg, Roland, MITSUBISHI, KOMORI and other foreign brands of ordinary people also can Xiang cooked ear. The three principle of offset: first, oil and water exclusion principle, chemical compatible principle to determine the so-called, have very mild The polarity of the different molecular structure of water and the non oil molecular polarity between molecules, which can not attract and between water and oil dissolved, this rule The existence of the plane plate to distinguish between graphic and blank and the idea of using water as possible. Two, the surface adsorption principle, According to the different surface tension is different, it cannot adsorption material, this is offset graph separation possible. Three, Dot like structure principle, because of the offset printing plate is flat, so do not depend on the thickness of the ink to print text layer Time, but with different levels of split into tiny dot unit visually imperceptible, can effectively show the rich The image level. In life we have such a common sense: the surface wet water, it is not easy to be contaminated by oil, water and oil are mutually exclusive. Due to the offset printing plate almost in the same plane, so it is necessary to find an effective distinction between blank part and the graphic part of the method, effect of water in offset, we called the "oil and water do not mix" principle. The printing process, first in India Version of the surface evenly coated with a thin layer of water (in fact, due to the selective adsorption, the plate surface text is not part of water Then, when the) coating on the printing ink, can effectively protect the blank part. Screen printing is the silk fabrics, synthetic fiber fabric or wire stretched on the network box, making screen by hand carved photochemical plate or film. Modern screen printing technology is making screen by photoengraving method using photosensitive material (screen hole in the screen for the hole hole, and part of the screen rather than the graphic part of the blocked). Squeeze through the printing scraper, so that the ink transferred to the substrate through the graphic part of the mesh, forming the same with the original graphic. Screen printing equipment is simple and easy to operate, Printing plate making simple and low cost, strong adaptability. Printing screen printing application scope is broad common: color paintings, posters, name card is designed to cover commodity signs and textile printing and dyeing etc.. Printing by five elements, namely the screen plate, squeegee squeegee, printing ink, printing machine and substrate. The basic principle is: the use of screen printing ink through the mesh screen plate graphic part, the basic principle and part of printing ink through the mesh. Pour the ink in the screen printing on one end, pressure parts of ink squeegee squeegee in the silk screen printing, and the other end plate moving toward the screen. The ink is extruded from the scraper and part of the mesh to the substrate on the move. Due to the viscous effect of the ink blot. In a certain range, always in the process of printing scraper and screen printing plate and a line contact, the contact line with the scraper moves, due to maintain a certain gap between the screen and substrate, so that the screen printing plate through the tension and cause of the scraper the reaction, the reaction is called resilience. Due to the rebound effect, so that the screen and substrate is only a mobile line contact, and the other part of the screen plate and substrate for out of state. The ink and screen the fracture movement, ensure the printing precision and avoid rubbing against dirty substrate. When scraper wind up after the whole layout, and silk screen plate also raised, and the ink scraping back to the initial position. This is a printing stroke. Gravure printing is engraving on metal surface is flat or cylindrical, made of intaglio plate, and then on the plate surface or plate immersed in the ink tank to obtain ink layer, by scraping the surface of the printing ink layer wiping, applied pressure, embedded graphic in ink layer is transferred to the substrate surface. 1, has the advantages of good quality, the solid ink layer; a stereoscopic, colorful, rich layers. Especially suitable for color printing all kinds of exquisite; 2, production speed, printing plate, quick drying, especially suitable for various commodities, large format printing; 3, low cost, printing material, wide adaptability, printing surface can withstand large plates can be used, especially suitable for long version of commodity packaging and decoration printing, and low cost. 4, very suitable for printing on metal materials. 5, a relatively simple mechanical structure, large format printing, suitable for processing line. 1, the disadvantages of high cost and short version of the product, is not suitable for; 2, the use of solvent based ink, not environmental protection. The principle of relief printing is relatively simple. In gravure printing, printing machine inking device to make the ink distribution, then the ink transferred to the printing plate through the roller, due to the graphic part relief is much higher than that of the graphic part, on the plate and therefore, only the ink roller transferred to the printing elements, rather than the graphic part no ink. Printing machine paper feeding mechanism of printing paper is transported to the parts of the printing machine, printing and embossing device in the common role of the device, a printing plate graphic part of the ink is transferred to the substrate, thus completing a printed matter. All printed paper prints a slight bulge, line or dot edge neatly, and ink in the center part is light, is letterpress. The image edge compression uplift is heavy, and the slight bulge marks Your picture is not embedded Excuse me, what is the gravure? What is the flexo? Michelle answer is very comprehensive, I add a little: Gravure and flexo printing are used in plastic products, according to the different plate material and the name, also known as gravure electric engraving, carving is the design draft in the steel tube of a cylinder, and cylinder to plastic printing machine; Flexo printing plate material is printed products, printing types using flexible version, is the use of water-based ink and UV ink. Flexo printing is a kind of direct printing, printing plate image projection has elasticity. A printing plate fixed on the printing plate cylinder. A printing plate by a metal roller engraving ink. Because the flexible version has great elasticity can be liquid or grease like ink to say to almost all types of materials. Flexo printing light brush pressure. According to the characteristics of flexo printing, in the choice of the original should be selected for flexographic printing manuscript: 1. designs for flexographic printing, such as lines, color with spot color is preferred. 2. too small text and line (especially white requirements) flexo printing is very difficult to achieve, let Liu should avoid. 3. shall be designed to avoid the strict registration requirements. 4. should also consider the characteristics of the printing machine and ink can be true to the original manuscript, half tone copy avoid the design and selection of large area high light and original pictures. 5. of the original size should be avoided in high magnification zoom in and out, because these will result in the loss of level. Excuse me, what is the gravure? What is the flexo? Thank you upstairs two ah. From the computer to plate printing (gravure or flexo), intermediate requires several steps? Gravure printing and flexo printing need a film? A film and offset the same? Excuse me, what is the gravure? What is the flexo? Gravure or flexo printing computer design and general design is different, need to design into 5 or more color edition version, which is normal, four-color color, with white background, the white spot color usually represented by gray, in addition to the gold / silver color and ivory black / Green / Blue / red / this. The color is not ordinary ink, many bright color proprietary dedicated channel design, need to separate plate, the design of color composition do not use superposition color, such as red with red, no M100 + Y100 stack, green without C80 + C100, but directly set to green, therefore, the key design of this project is the color composition and distribution problems, the whole color seihan process complex, late big trouble, well prepared, more than 10 edition, do not printing factory Willing to do, the customer cost increases greatly, will very much want. Excuse me, what is the gravure? What is the flexo? Ha-ha。。。。。 I was doing the film output, but these did not know how Excuse me, what is the gravure? What is the flexo? Do the film output responsibility and not others is how to design, how to design data, however, if encountered playin type, such as do not know the post production process, no printing techniques can suffices, data confusion survey does not say, some waste to life. Excuse me, what is the gravure? What is the flexo? I was Netcom card, yesterday could not reply reply. Gravure and flexography is there a difference? They make many color requirements like aluminum foil paper, aluminum foil paper printing pictures are printed on white ink. If it is to be printed in green spot color. Two printing products will dull a lot, very good printing brightness. So basically is a spot color printing. Add color was ugly, and is the sum of three and four. So a lot of color. The prepress documents in addition to the above spot, any other requirements? The file needed to complete the film piece? I heard a gravure printing down 50% (in the end how to drop 50%?) I also heard that, without a direct gravure printing, engraving in iron drum. Would you like a piece of [[[on the gravure printing? To a 50% word how down? ]]]
