Excellent on-board stability reduces dot gain and reduces color change after drying
The osmotic component in the ink can smoothly penetrate from the ink film to the paper, and the drying is fast, the waiting time of the post-processing is reduced, and the wear resistance is good.
Enhance the applicability of post-press processing, good dot reproducibility, clear printing dots, and strong stereoscopic prints.
The printing body after printing the ink can be directly varnished or directly subjected to a laminating process, and the ink is very cost-effective.
Hanghua offset ink 8000 series 8601 green:
Used to match spot colors and direct printing gold red. Suitable for all kinds of packaging, books, brochures and other paper printing, suitable for monochrome two-color four-color printing, used in various types of printing machines such as: Heidelberg series, KBA series, Komori series, Mitsubishi series, Beiren series and so on.
Dirty: refers to the appearance of many ink stains in the non-image area of ​​printed matter, which is a common and representative fault in lithography. This phenomenon is caused by many factors such as ink, paper, printing plate, printing syrup, etc. From the ink point of view, it usually occurs when the ink is thin, soft, yield value is too high, and the viscosity is insufficient. The performance, adding a moderate amount of viscosity resin varnish or bright varnish to help overcome the dirt; when the ink is formulated, the desiccant, low viscosity varnish, debonding agent added too much, the ink is thin The viscosity is small, which is an important reason for this disadvantage. The ink can be properly formulated and replaced with fast-solid light ink. Secondly, the unevenness of the printing plate, the residue of the abrasive material, the lack of non-lipidization, the partial oxidation of the plate, or the lack of development are also important factors for the occurrence of dirt, and should also be checked and solved, and the roller of the printer is poorly arranged. The water roller is dirty, the rubber roller rubber is aging, and the blanket is loose, which may also cause dirt. It should be checked and adjusted.
Thickness: It means that the pigment is separated from the ink and accumulated on the plate and the blanket, resulting in a paste dot of the printed product. Under normal circumstances, the ink is poor in water resistance, and this phenomenon often occurs when it is easy to emulsify. It can be added with high-viscosity resin varnish, bright varnish or printing varnish to improve the viscosity, transferability and water resistance of the ink. At the same time, increase the PH value of the printing syrup, reduce the water supply, reduce the amount of ink, and improve. Or overcome this failure.
Dirty: dirty, also known as "dirty", "stained back", printing speed is too fast, the ink on the paper is not fixed enough time or the paper pile pressure is too large, the ink layer is not dry, the ink is transferred again The phenomenon is called sputum. This phenomenon is easy to appear in high-speed four-color, two-color printing. The most fundamental measure is to use fast-solid light, fast-fixing ink printing and dusting, to adjust the amount of powder sprayed, and to reduce the supply of ink color and concentration. The amount of ink, reducing the pressure of the accumulation of printed matter, reducing the amount of water, helps overcome the smudging phenomenon.
Paste plate: Paste plate means that in the printing process, the ink appears in a very light color, and a large area appears in the blank space of the layout. After wiping off, it will appear in other places soon. The appearance of the paste phenomenon is generally due to the poor water resistance of the pigment in the ink, improper adjustment of the ink formulation, excessive use of the detackifier, low viscosity varnish, and the ink blending too soft and too thin to cause the paste. To solve this problem, one is to use a good water-resistance ink, and the other is to adjust the amount of various printing auxiliaries to ensure the water resistance and ink balance of the ink.
Pulling paper: Printing high-grade coated paper, glass cardboard, matt paper, generally does not appear this problem. If the surface of the paper is rough, the strength is not good, the adhesion of the paper coating is not strong, and the viscosity of the ink is relatively large, which can cause the phenomenon of pulling the paper and cause the printing quality to decrease. In this case, it is a simple and economical method to reduce the viscosity of the ink or to change the viscosity of the ink as small as possible, so that the ink film is easily split during the imprinting, and the printing speed is reduced. better.
Crystallization: crystallization is also called vitrification. The phenomenon is that after the ink printed first is dried, the ink is not printed on the printing or even printed, the ink layer is easily peeled off after drying, and the fast-solid gloss ink and resin after the resin is resinized. Offset inks are less common in such problems, and occasionally when printing large prints or prints with too thick ink layers. The solution is mainly to reasonably master the overprinting time of the next color, overprinting when the previous color is not completely dried, and secondly controlling the amount of dry oil. The excessive addition of dry oil is the main factor that promotes crystallization.
No ink: also known as ink roller, refers to the phenomenon of streaks in the printed matter, the hue is relatively light. This phenomenon is mainly caused by poor ink quality, high yield value, high pigment content in the ink, too short ink head, cheese gelatinization, ink gelation or water entering the ink causing partial flocculation. The ink in the ink tank of the printer is separated from the ink roller and cannot be transferred well. In order to solve this problem, the ink and the fluidity of the ink are firstly improved from the ink design. Secondly, when printing, proper mixing of viscous oil with high viscosity can improve the fluidity of the ink, which can help overcome the ink with high thixotropy and viscosity and fluidity. The ink in the ink tank is often stirred by the ink knife or It is also possible to overcome this disadvantage by installing a stirrer directly in the ink tank.
Flying ink: refers to the ink flowing between the rotating ink rollers during the printing process. When the ink filaments are separated due to the surface tension, they become charged small particles and are expelled from the space by the running printing machine. phenomenon. The phenomenon of flying ink increases with the thickening of the ink layer of the roller, and the speed of the printing machine increases rapidly, which seriously increases the quality of the printed equipment and the printing environment. This phenomenon occurs mainly because the viscosity of the ink is not compatible with the speed of the printing machine, and is generally caused by the viscosity of the ink, the length of the filament, and the softness of the ink. The ink has poor water resistance and can fly when it is easily emulsified. The solution is mainly to reduce the viscosity of the ink and improve the water resistance of the ink. Use a harder and higher concentration ink to reduce the amount of ink, the ink layer of the roller is thinner, and the flying phenomenon will be improved.
Drying too fast: refers to the phenomenon that the ink is thickened and dried in the ink fountain, on the ink roller, and on the blanket. This phenomenon is mainly caused by too much desiccant in the ink, which contains more solvent that evaporates too quickly; the temperature in the printing workshop is too high, the air is too dry or the air circulation is too good. The solution is mainly to add a small amount of petrolatum to the ink to reduce the drying speed of the conjunctiva; add a small amount of anti-skinning agent or antioxidant; the ventilation of the workshop should not be too good.
Expansion of outlets: mainly on the outlets of the edition, which cannot be faithfully reproduced. As a result, the dots are deformed or connected, and the contrast is insufficient, which affects the quality of the printed products. This phenomenon is mostly caused by improper ink mixing, too thin and too soft ink, and insufficient concentration. When adding ink, add appropriate amount of detacking agent, do not use thinner varnish to remove viscosity, or use higher concentration ink to reduce ink supply. This phenomenon can be overcome, the hardness of the ink roller is not suitable, the roller pressure is too large, the blanket is slack, and the roller arrangement is also an important cause of this problem, and it is also checked and adjusted. Ink and printing workers are very clear, there is no universal ink, can adapt to a variety of printing machines, paper, printing environment and different printing needs, so printing should be based on different conditions, the ink is necessary to adjust the ink It is also very important, properly deployed, can reduce a lot of printing failures.
