Modern Certificate Making Technology           In the application industry of packaging and printing, card materials are mainly plastics, including PVC, polyester, ABS plastics, etc. their performance is different from that of conventional similar materials.Modern Certificate Making Technology         For example, in order to prevent non-destructive stripping after hot pressing, the certificate substrate is required to have wrinkle resistance and tear resistance, while most of the conventional PVC is transparent, and it must have high light blocking performance for certificate preparation.Modern Certificate Making Technology   For example, copying watermark, adding security line, mixing special components, micro printing, broken line wiring, invisible pattern, setting secret mark, magnetic and color changing ink, unconventional signs (such as hologram, cursor image), IC chip, etc.Modern Certificate Making Technology     & […]

Environmental Harm of Printing Ink and Development of Environmental Protection Ink       With the increasing voice of environmental protection, as the main part of green printing, the requirements for environmental protection of ink are also increasing. It can be said that environmental protection ink is the first consideration for the development of ink in the future.Environmental Harm of Printing Ink and Development of Environmental Protection Ink   One Harm of ink to environment       Ink is the largest pollution source in the printing industry, and the annual output of ink in the world has reached 3 million tons. Global Organic volatiles caused by ink every year (VOC) pollution emissions have reached hundreds of thousands of tons. Environmental Harm of Printing Ink and Development of Environmental Protection Ink        These organic volatiles can form a more serious greenhouse effect than carbon dioxide, and will form oxides and photochemical […]

Analysis on Key Points of Post Printing Binding in Digital Printing        Only by carefully designing and arranging the printing from the beginning can we ensure the harmony between printing and post press processing.Analysis on Key Points of Post Printing Binding in Digital Printing During production, the following points shall be noted: 1. Folding        Because the ink pigment on the digital printed matter is only attached to the paper surface, folding processing is easy to break. Therefore, it is best to press creases before folding processing. 2. Film covering         Laminating the surface of digital printing, especially after printing a large area of field, will help to protect the printing in post press processing, especially in cutting or packaging. It may not be beneficial to cover double-sided printed matter on one side, because the uncoated side may be more prone to peeling off of printing pigment due to friction in subsequent proces […]

Influence of Ink Thixotropy on Printing         Ink thixotropy is one of the properties of printing process, which has a great impact on the quality of printing products.Influence of Ink Thixotropy on Printing         Thixotropy refers to the phenomenon that the ink becomes thinner or thicker and the fluidity changes under the action and influence of external forces and external environmental factors. For the printing process, stable product printing quality requires that the ink should maintain appropriate and stable fluidity. Influence of Ink Thixotropy on Printing          However, due to the inherent factors of ink itself and printing conditions, the ink will inevitably appear “thixotropy” in the printing process, which affects the stability of product quality. Therefore, we should correctly understand the thixotropy of ink, take some measures to overcome and make up from the process and technology, and reduce the thixotropy degree in ink printing, so as to better ensur […]
