Prevent scratches smooth feed across the entire printing press is continuous throughout the press a prerequisite for improving print quality. Speedmaster SM74 using three feed roller to smoothly complete feed in Shanghai between different printing units. Coupled with the drum jacket technology, you can achieve smooth feeding without any scratch without any glue is dry ink on paper - is true even at the highest printing speeds. With endless choice of substrates Speedmaster SM74, you can handle a variety of substrates - from thin paper to card. This is designed for feeding from .03 to 0.6 mm (.0012 to 0.024 inches) thick all materials. Always print quality effectively monitored by an optical principle based on the sample detector can reliably check carefully and ensure a smooth paper conveying speed without affecting the printing and printed material. Speedmaster SM74 can be detected quickly enough or missing paper size. Transfer paper jacket TransferJacket- more time, more flexibility with replaceable feed roller surface of the sheath, which has a strong ink repellency of transfer paper jacket TransferJacket. Special surface structure prevents the accumulation of the ink, so that you can greatly reduce the number of cleaning rollers. Transfer paper jacket printed just TransferJacket ensure an orderly and smooth paper can be transported to the next printing unit. Color pages printed in color in the grasp of human vision is the first key is a manifestation of the focus of advertising, a personalized color, often better grab consumer's attention, through a combination of specific color image, the use of different colors, so that the audience reflect different physiological and psychological associations, establish a solid product image in Dongguan, where a good book printing to produce pleasing intimacy, attraction and promotion of consumers' desire to buy. Color not exist in isolation, it must reflect the texture of commodity, specialty, but also beautify the decor of advertising space, at the same time with respect to the environment, climate and enjoy the habits to adapt, but also take into account the far and near, large and small visual changes in the law, to make it more full of beauty, as an important part of advertising. General said color page color printing graphic design mainly corporate color, commodity color image, and seasonal symbol color, fashion color, etc., as the main colors, high contrast contrasting lightness, purity and hue of the screen image and highlight background of relations, highlighting advertising screen contrast and the surrounding environment, to enhance the visual effect of advertising. While the use of color must consider its symbolic significance, so as to more appropriate theme, such as red, reflecting the colors are strong, can cause muscle excitability warm, impulsive; Green Dongguan book printing, with neutral characteristics. peace color, favor natural beauty. tranquil, vibrant, color tolerance can be set off multiple colors and harmony. Give full consideration to these colors symbolic meaning, connotation increased advertising. Shanghai charging the drum surface light conductor laser printer printed material not seen in the case of light is an insulator, a neutral state book printing factory in Dongguan, without any charge. To achieve the light conductor surface 'electrostatic latent image', must be charged in the light conductor surface, so that charge. Only then, when the laser beam is scanned on the photoconductor, light conductors are exposed point is turned on, form a beam lattice. Charged with the substrate lattice conduction form 'latent potential difference', when the photosensitive drum is rotated to the developing magnetic roller tangent position, the magnetic roller carrying light conductor and surface charge properties of the toner attraction to the opposite surface of the drum, whereby the photosensitive drum showing a toner image. To make the photosensitive drum in accordance with graphic information can be adsorbed on carbon Dongguan album printing prices, should be carried out on the drum, the charging electrode is a drum shaft parallel with the tungsten wire, with 5 ~ 7kV on DC high voltage, When the drum surface with the tungsten is very close to the surrounding air is ionized corona discharge, the photosensitive drum to bring a charge. Positive and negative voltage from the voltage tungsten brought the decision, if the photoconductive material is selenium tellurium alloy, is positively charged photosensitive drum after the revolution of the entire surface are charged.
