The purity of ink is the core prerequisite for determining its printing effect, service stability and equipment adaptability. As the “quality gatekeeper” in the ink production process, the filtration link directly determines the residual amount of impurities in the ink, and is also a key process to ensure product consistency and reliability. Its importance runs through the entire process of ink production.
In the ink production process, links such as raw material mixing and grinding will inevitably produce tiny solid particles, incompletely dissolved components, or introduce external impurities. Even if these impurities are at the micron level, they will seriously affect product quality and user experience—not only will they cause defects and uneven colors in printed patterns, but they may also clog print nozzles, shorten equipment service life, and even affect the chemical stability of ink, leading to precipitation, stratification and other problems, which greatly reduce product competitiveness and user satisfaction. Therefore, an efficient and precise filtration process is not only a necessary link in ink production, but also a core embodiment of an enterprise’s commitment to quality and technical strength.
To eliminate impurity hazards from the source and create higher-purity, more stable ink that is more suitable for various printing scenarios, SUPERINKS has always adhered to the production philosophy of “details determine success, pursuit of excellence”. It has continuously deepened and upgraded its filtration technology, innovatively adopting a dual precision filtration system of “3-level one-way filtration + 3-level circulation filtration”, building an all-process, non-dead-angle impurity interception line of defense, and guarding the purity of every drop of ink with strict standards. As a technology service provider deeply engaged in the inkjet field, SUPERINKS has been focusing on the R&D and production of ink and other products since its establishment in 2013, integrating quality control into the entire production process. This upgrade of the filtration process is a practice and adherence to the brand’s original aspiration.
Compared with the traditional single filtration mode, the six-level filtration system adopted by the company achieves a “layer-by-layer progression and precise interception” filtration effect. The filtration accuracy is gradually upgraded from 0.45μm to 0.3μm, gradually separating impurities of different particle sizes in the ink, ensuring that the purity of the final product meets the high industry standards. In terms of filter element selection, we balance filtration effect and service stability, and scientifically match glass fiber filter elements with titanium filter elements——glass fiber filter elements, with their dense fiber network structure, have excellent interception efficiency and dirt-holding capacity, which can efficiently intercept medium-sized impurities and lay a foundation for subsequent precision filtration. Their unique three-dimensional structure can also ensure filtration flux and reduce filtration resistance; titanium filter elements are made of industrial high-purity titanium powder through high-temperature vacuum sintering, with the advantages of uniform structure, narrow pore size distribution, strong chemical stability and no particle shedding, which can achieve 0.3μm-level precision filtration and completely intercept tiny impurities. At the same time, their high temperature resistance and acid-base corrosion resistance can adapt to the complex working conditions of ink production, avoid secondary pollution caused by filter element loss, and meet the strict requirements of high-quality ink production.
In addition to advanced filtration equipment and scientific filter element matching, SUPERINKS has also established a standardized filter element maintenance and replacement mechanism, strictly stipulating that the filter element should be updated in a timely manner for every 400KG of ink produced. This eliminates the decline in filtration effect caused by filter element loss and dirt saturation from the process, ensuring that the quality of each batch of ink is always stable and uniform, and eliminating batch differences. This standardized operation is not only a respect for quality, but also a direct embodiment of SUPERINKS’ responsibility to users, demonstrating our production attitude of “not ignoring every detail and not compromising every standard”, and also conforming to the company’s professional commitment after years of deep engagement in the industry.
Quality is the lifeline of an enterprise, and technology is the cornerstone of quality. In the future, SUPERINKS will continue to be user-demand-oriented, relying on its own R&D strength and production experience, continuously deepen and refine every link of ink production, constantly optimize filtration technology and upgrade production technology. With more advanced technology, stricter standards and more rigorous attitude, we will create more high-quality and stable ink products, empower the development of the printing industry with technological innovation, win market trust with quality commitment, uphold the original aspiration, forge ahead, and strive to be a quality benchmark in the ink industry!
