Ink in the printing process, the ink caused by the failure is frequent, greatly reducing the print productivity and print quality. For example, offset printing ink skin is unavoidable, which often appear in the field and ink of live parts in the event, usually stop processing, Dongguan product box printing, if more long runs down, then the speed is not to yield certainly be affected; and if short runs down more often, it is difficult to ensure consistent ink, resulting in job quality has declined markedly. Thus, the operator in the face of such problems, should be carefully observed, more brains, analyze the causes and timely manner, can not meet the ink skin on blindly down process, under which the majority of cases related to the ink properties, for example, the case of the cold of winter, if appropriate ink additive increased mobility, can reduce ink leather production. In addition, the best selection of high-quality ink, in general, the quality of imported ink more stable, relatively small ink skin breakdown, suitable for long-term use, can improve printing productivity. Ink cleaning tips driers species are fatty acid, naphthalene acid, cobalt octane acid, manganese, aluminum and the like. Offset printing, offset printing ink can not be separated, it ultimately ink cleaner. Thus printer manufacturers ink cleaner front, Dongguan box printing company, which will be given specific instructions on press engineering manual. Moreover, some of the ink also contains glial calcium carbonate filler. Currently black pigment used in printing inks, mostly inorganic, Dongguan PVC box printing, and color ink more for organic pigments. Fountain solution consists of water, inorganic compounds and acacia composition, hydrophilic very good. Offset inks commonly used binder with vegetable oil and solvent oil type. These salts can be oxidized by oxygen in the air, which increased after the metal ion valence oxidation strengthen, promote drying oil oxidation polymerization reaction, such additives oxidative polymerization of drying oil crosslinked film-forming reactions catalyzed effect. Ink cleaning agent is mainly divided into two categories: one is gasoline, kerosene, and the other is printing special cleaning agent (commonly known specialty is "ink cleaner"). Offset printing ink according to their molecular structure belongs to an organic substance that can be dissolved organic solvent, and the pigment ink are neither soluble in water, box printing, not soluble in organic solvents, only have a certain affinity for water. Press the main mechanism of the ink drying ink into oxidative polymerization drying, penetration leaking drying, evaporation drying type and photo-curable four categories. Whatever the type of printing ink common requirement for them is: transfer printing process to the surface of the paper before, it is necessary to keep alive the idea of ??chaos energy; and after the transfer to the paper surface, it is necessary to lose activity quickly dried and cured ; inks have good adhesion to substrates; inks should have good transitive; graphic printing ink on paper composition necessary to maintain accurate and lasting glory. According to statistics, the total output value of the world's printing, offset ranked first, the "Queen of the analog printing" reputation. Box printing company in Dongguan, beyond printing (online consultation), box 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.
