Laser printers method of charging the photosensitive drum Huang Jiang manual printing, specific charging methods vary by model and uses are also different, but basically the same principle of charging brochures printed, and are based on DC high voltage corona discharge for charging the drum surface. In the charging process, the photosensitive drum adsorption charged toner, is most likely the first part of the environmental impact of building the stage. In this session, if you are using a compatible consumables, or filling toner, it can easily cause carbon adsorption process as going into the atmosphere, and this release is a very small toner particles Such particles can be accompanied by our breathing into the lungs, the long run is bound to impact on our health. The developing process of the photosensitive drum when the electrostatic latent image formed on the surface, the toner image after developing shows, this process is "developing." Development work done by the developer, whose role is the electrostatic latent image into a visible image. When we print paper into the machine, the paper will be in contact with the photosensitive drum before, is full of negative charge. When the print paper in contact with the photosensitive drum, the electrostatic latent image with a positive charge and the printing paper will have a negative charge attract each other, thereby adhering to the print paper, thermal transfer unit after heating the toner particles to the paper outer fiber absorption, eventually forming the printing image. Finally, the printer will automatically remove the remaining toner on the photosensitive drum, and the potential of conversion, so that the next cycle begins. Stamping control the temperature. Stamping off layer and melting temperature adhesives have a greater degree of influence on the hot-melt silicone resin, hot stamping foil temperature must not be below the lower temperature range, which is to ensure the lowest melting temperature foil adhesive layer. If the temperature is too low bridge printing brochures, melting insufficient cause or stamping on stamping not strong, the blot is not strong, incomplete, missing or broken dash pen blur; while the temperature is too high, excessive melting, causing Imprinted foil around the attachment also melted off and paste version Hengli printing brochures, while the high temperature will make the color layer of synthetic resin and dye oxidative polymerization, blotting blistering or patchy fog, and lead to the surface of the aluminum layer and a protective layer oxidation, stamping products to reduce the brightness or lose metallic luster. In general, electric temperature should be between 80 ~ 180 ℃ adjustment, stamping larger, electric temperature is relatively higher; on the contrary, it is lower. Specific conditions should be based on a variety of factors, the actual temperature of the plate, foil type, graphic status is determined, usually to identify the most suitable temperature by trial and hot, and they can be imprinted with the lowest temperature a clear graphic lines standard. Stamping pressure to a reasonable grasp. Foil stamping pressure and for adhesion to a great relationship. Even right temperature, if the pressure is insufficient, can not make the foil substrate and cement, or produce fade, imprinting blur and so on; the other hand, if the pressure is too great, the pad and substrate of compression would be too large, resulting paste Version or blotting thicker. It should therefore be carefully adjusted Stamping pressure. In addition, similar to the stamping pad should also be noted that for a smooth paper, such as: coated paper, glass, cardboard, paper best selection of rigid liner, blot thus obtained is relatively clear; on the contrary, the smoothness of the poor , more rough paper, the best liner softer, especially stamping area and at large. In addition, the stamping pressure must be uniform, if you find a local stamping on when proofing not produce flowers or hemp, pressure here may be uneven. Place tissue on the premises of the plate, make the appropriate adjustments. Pictures, color and line, I want to place picture frame, can not exceed the size of the production, but also to avoid using white color. Pictures of the words in the word using the system, to be converted into a description of the frame or curve, in addition there is no overlap between the note and skip between words, black text can not be used to fill overprint. If printing the same document in different secondary, there will be differences in color and normal color degree should be within 10 percent. If the design documentation tools are used CoreIDRAW9.0 Chinese version, Mac documents designed to be replaced by PC format. Also, if there are broken or do not want to print the situation can not be presented at the input or draw their own graphics, the frame thickness greater than 0.1mm. Dongkeng printing brochures, beyond printing (certified), brochures printed by the Dongguan City, often beyond packaging products factory provided. Dongguan Chang-ping beyond packaging products plant (www.dgcyp.com) Dongguan, Guangdong, printing paper leaders, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In all walks of life beyond the printing leadership with the staff warmly welcomed the inquiry negotiations to create a better future beyond printing.
