Product Introduction
Key Performance Characteristics of Offset Inks for Engraving Printing
High-precision presentation: Offset inks used for engraving printing must have extremely high precision performance capabilities. The printing plates of engraving printing have extremely fine graphic structures, and the ink must be able to accurately fill these tiny areas, so as to present sharp and clear lines and patterns on the printed products.
Good transferability: Due to the particularity of engraving printing, the ink needs to be smoothly transferred from the printing plate to the rubber blanket, and then accurately transferred to the substrate. This requires the ink to have appropriate viscosity and stickiness, so that it can be efficiently transferred between different surfaces. Appropriate viscosity allows the ink to adhere well to the printing plate, while appropriate viscosity ensures that the ink will not spread or accumulate excessively during the transfer process, maintaining the clarity of the pattern.
High color saturation: In order to make the works of engraving printing bright and vivid, this type of ink needs to have a high concentration of colorants to achieve high color saturation. Whether it is a bright color engraving print or a work that is mainly black and white but emphasizes contrast, high-saturation ink can enhance the visual effect and highlight the layering and three-dimensional sense of the engraving pattern.
How to choose high-concentration offset ink for specific printing needs?
Securities printing: tends to have low gloss to reduce reflections to facilitate authenticity identification and enhance anti-counterfeiting; and the gloss needs to remain stable in the long term to maintain authority and recognition.
High-end packaging printing: often requires high gloss to enhance texture and attract consumers; at the same time, requires uniform gloss to ensure overall beauty.
Art print reproduction: according to the style of the original work, traditional works mostly simulate low-medium gloss to restore artistic texture; modern works may use high gloss to enhance expressiveness, and the gloss needs to be adjustable to be close to the original.
