1, affect the viscosity of the ink colors in General ink sequence arranged in descending order of viscosity should, prevent the same color ink before adsorption same color ink. But when the original claim is limited so that a full-page color bias which inks, such as cyan, in arranging the color order, should the blue India, then consideration should be given to the cyan viscosity is too large, adding a certain amount to the viscosity of the ink inside, to reduce its viscosity, the prevention of color mixing phenomenon occurs. 2 and the depth of the ink and coloring rate of the average domestic ink in the actual production rate of its coloring coloring than its standard rate index lower, in order to achieve the same density in the printing field, is bound to increase the amount of ink that is increasing the thickness of the ink. Because the ink is not dry, ink thicker, more likely to be an external force (printing press) interference and sabotage, but also easy to produce color mixing phenomenon. 3, affect the ink drying performance in actual production, ink drying early grave, where particular attention sky blue ink dongkeng proposed book printing, when the machine is running, cot gradually heat, especially in summer. The ink began to change in the cot, the viscosity increased gradually transferred to the blanket after the situation is more serious. Then often cause color mixing phenomenon. J2205 machine in India for example magenta, cyan, the opening print properly, but printing to a certain amount (thousands of sheets), the careful observation, magenta ink gradually darken trend. Solve this problem, the operator is required to master the ink drying performance. 4, be sure to pay attention to the printing ink balance out of control if the ink-water balance, will cause "water" big "ink" big, stay on the ink fountain roller corresponding increase, equivalent to increasing the diameter of the ink roller, increasing the pressure between the rollers, the ink roller heats up, the more easy to dry the ink, the ink viscosity also increased, resulting in a series of vicious circle, can easily result in color mixing phenomenon. Printing speed as constant as possible. Contact time with stamping fastness under certain conditions is directly proportional to the speed and determines the contact time stamping foil and substrates. Stamping speed, long contact time with the substrate foil, bonding is more firmly in favor of stamping; on the contrary, stamping speed, short exposure time stamping, foil hot-melt silicone resin layer and adhesive Not completely melted, it will not lead to stamping on or blot blur. Of course, the printing speed must also be pressure, temperature adapt, if printing speed increases, the temperature and pressure should be appropriately increased. Foil stamping itself affect the performance of the speed as well. Good quality foil stamping can achieve rapid, large that domestic and imported anodized aluminum foil difference. Domestic foil stamping are usually only suitable for low speed, the rate of about 2000 / h, the maximum is generally not more than 3000 / h; imports may reach 8000 / h, or even higher. But no matter what the speed, the important point is: printing speed should remain relatively stable as possible, do not change easily. On the premise of stable speed stamping, stamping adjust temperature and pressure so that the best of stamping, thus reducing the variable factors, so that a stable operation, easy to control the quality of stamping. Stamping version generally copperplate, zinc plate and resin version, relatively speaking, the best copperplate, zinc plate moderate, resin version somewhat less. Therefore, for fine stamping, as far as possible with copperplate. For stamping version, requiring that their surface roughness, graphic lines clear, smooth edge, no pitting and burrs. If the surface is slightly uneven or mild abrasion, when fluff, gently wipe the available fine carbon, making it smooth. Stamping Edition rot Version depth should be slightly deeper, at least more than 0.6mm, slope about 70 °, in order to ensure the stamping clear graphics, reduce the appearance of lace and paste version, while improving the resistance rate. Stamping text, lines and patterns design is very particular about. Photo should be as moderate thickness, density and reasonable, such as too small and thin, easily broken lack of pen stroke; too thick too close, it is easy to paste version. Printing in the final analysis is a replication technology to copy graphic images to make the above substrates. Traditional printing technology is divided into convex, flat, concave, missing four ways, a common feature of the four printing plates is achieved through graphic image replication. Among them, in addition to screen printing were missing the most commonly used surface printing can be achieved, the other can only be printed in several printing medium on a plane. Inkjet printing technology is different. Like other digital printing technology Huang Jiang, book printing, inkjet printing technology is not printing. Graphic inkjet printing technology is to be replicated printing directly on the substrate, if handled properly, even a curved objects book printing, you can achieve a good image quality. In reality, people use inkjet printing technology Hengli book printing, not only the surface of the printed surface of the object, and has achieved a print on irregular surfaces. At the same time, with the advent of UV ink technology, many of the original can not be printed dielectric materials, can now be printed using inkjet technology. Inkjet printing has greatly expanded the range of printing materials and surface morphology can be printed, which undoubtedly can cover a wider field of printing objects that can be served is broader. Changping book printing, beyond printing (certified), book printing 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.
