What are the steps of the printing process?

Basic flow of the printing process: design into a map, proofing, collage, plate, printing on the machine, post-press processing, delivery of the film (i.e., send film film film) out of the film is to make a good layout, through the equipment output to the PC film can be printed, the terminology is called film film sheet. FILM SHEET: The film used for printing plate making is called film sheet, and it is equivalent to the negative of a photo when it is printed on a PS plate. It is an essential process in precision printing. Color printing film sheet usually contains 4 (CMYK each one). Proofing: in the printing production process, with the photographic method or electronic color separation machine and made the appropriate trimming of the negative, before printing into the proof or other methods to show the effect of plate making process. The purpose is to confirm the printing production process of setting, processing and manipulation is correct, to provide customers with samples of the final printed materials, and does not require the visual effect and quality with the final printed materials finished the same. Proofing can be roughly divided into three methods, namely, proofing machine proofing, (color powder) simple proofing, digital proofing. Proofing machine proofing, the most traditional and most reliable method of proofing. It uses similar equipment, printing plates, paper and ink with the official printing machine, but the proofing machine is generally a single-color or two-color machine (a run can only get one or two colors), the degree of automation is not high, requires a high degree of operational skills and experience, and must be made in advance of the printing plate, so the proofing machine proofing is inefficient, requires constant temperature and humidity environment control, and the cost is high. This proofing method is widely used in China, Japan and other countries. Simple proofing a use of photochemical reactions to obtain images and color proofing technology, mainly laminated film proofing and toner proofing two. These two methods of *** with the same characteristics of the dichroic dot film (such as the yellow version) and attached to the film or paper substrate photopolymer coating superposition (using a vacuum method), through the dichroic mesh film side of the ultraviolet light source for exposure, so that the exposure part of the insoluble or the loss of adhesion, and then through the solution development or toner development, you can get the color image. The difference is that the former use were carrying yellow, magenta, cyan, black pigment photopolymer coating of four films, will be exposed, solution development processed film stacked together to get a transmissive color sample; the latter use a sheet of paper with the same as the actual prints, will be a colorless adhesive polymer coating (similar to self-adhesive) attached to the top (with a special laminating machine), after exposure, Toner development process, repeated four times, you can get a reflective color sample. Toner proofing from the mid-1970s, in Europe, the United States and other countries are widely used, but due to the imaging process and the actual printing process is very different, it is difficult to do the sample and prints are completely consistent. Digital proofing is different from the above two methods, neither the need for intermediary color separation dot film, also do not need a printing plate. Digital pre-press system (computer) generated in the digital color image (also known as digital page or digital film) directly into a color sample, that is, from the computer directly out of the sample. Digital proofing is divided into soft proofing and hard proofing. Soft proofing is a digital page directly in the color monitor (such as computer monitors) on the display, it can do with the computer processing real-time display, has the advantages of fast speed, low cost, but because it is the principle of additive color rendering, and the material and the observation conditions with the actual prints are far away, and now there is the use of liquid crystal displays soft proofing, there have been improvements. Hard proofing as in computer color inkjet, digital pages directly into color hard copy (using inkjet printing, dye sublimation, thermal wax transfer, color electrostatic photography and other imaging technologies). Due to advances in computer image processing and analog, control technology, although the paper and color presenter are not exactly the same as the actual printing, but the digital hard proofing has been able to do with the actual print effect is very close to the high-quality products (such as dye heat sublimation) can reach more than 95% of the exact same. Digital proofing is the early 1990s only the rise of the proofing method, but its fast, efficient and direct digital conversion features and printing technology digitalization and networking of the development of a perfect match, the beginning of the 21st century has become one of the main proofing method.
