What Are The Basic Processes of The Printing Process?

The basic process of the printing process are: design drawings, send the film, proofing, collocation, solarization, post-press processing, delivery.

First, hair film (hair film sheet) out of the film is to make a good layout, through the equipment output to the printable PC film, the technical term is called film. Film: The film used for printing and making plates is called film, which can be printed on a machine with a PS version of the film, which is the same as the negative of a photograph. It is an indispensable process in precision printing.

Second, proofing: in the printing production process, the film made with the photographic method or electronic color separator for appropriate trimming, and the use of proofreading or other methods to show the effect of plate making. Proofing machine proofing the most traditional and reliable proofing method. It uses similar equipment, plates, paper and ink with the official printing press, but the proofing machine is generally a single-color or two-color machine (only one or two colors can be obtained at a time), the degree of automation is not high, requires a high degree of operational skills and experience, must be made in advance of the plate, so the proofing machine proofing is inefficient, requires a constant temperature and humidity environment control, high cost. Simple proofing a photochemical reaction to obtain images and colors of the proofing technology, mainly composed of laminated film proofing and color powder proofing, the common feature of these two methods is the color separation dot film (such as the yellow version) and attached to the film or paper substrate photosensitive polymer coatings (vacuum method) superimposed on each other, the exposed portion of the exposure through the screen film side of the exposure of ultraviolet light source and become insoluble or lose adhesion, and then through the solution development or color powder development to obtain a color image. Digital proofing does not require an intermediate color separation dot film or a printing plate. Digital color images generated in a digital prepress system (also known as digital pages or digital film) are converted directly into color samples, i.e. a sample is generated directly from the computer. Digital proofing is divided into soft proofing and hard proofing.

Third, platting platting is also known as “mounting”, “group plate”. The second process is manual typesetting. In the work will not always do 16K, 8K and other formal open products, especially boxes, small cards (certificates), etc. are often not closed, at this time we need to pay attention to the finished product as much as possible in the appropriate range of open paper, in order to save costs. Fourth, the sun plate photocopying is in the film, sulfuric acid paper and other high transparency carriers, through the exposure of the screen, PS, resin and other materials, coated with a photosensitive agent, the picture and text print out the work. After drying on the screen, PS, and resin plates, a film of the image is covered with it, and the image on the film is exposed and photocopied onto a photosensitive film on the plate. This exposure photofinishing process is often referred to as solarization.

Fifth, on the printing machine will be good sunshine PS plate repair to the rubber rollers of the printing machine, adjust the ink, open the printing. Sixth, post-press processing lamination, embossing, folding, laminating, UV, binding, embossing, hot stamping, hot stamping silver and other printing processes.
