PS Plate: An innovator of printing technology and a powerful assistant for artistic creation

PS Plate, or Presensitized Plate, is an indispensable and important material in the printing industry. As the core component of lithographic offset printing plates, PS Plate has become an important part of modern printing technology with its unique performance and wide application fields.

The preparation process of PS Plate is a complex and delicate process. The aluminum plate is used as the base, and after electrolytic oxidation treatment, a dense layer of sand grain is formed on its surface. This layer of sand grain not only increases the roughness of the plate surface, but also improves the hydrophilicity of the plate surface. The non-silver photosensitive (thermal) resin layer is coated on the aluminum base to form a uniform photosensitive layer. This photosensitive layer plays a vital role in the printing process, which determines the ink affinity of the plate surface.

During the preparation process, the quality of the aluminum base has a direct impact on the performance of the PS Plate. High-quality aluminum base can ensure the uniform morphology and distribution of the electrolytic sand grain, thereby improving the printing quality and service life of the PS Plate. However, problems such as airway defects on the surface of the aluminum base have always been one of the main reasons that plague product quality improvement and high-end market development. Therefore, quality control of the aluminum base is crucial during the preparation process.

PS Plate is unique in the printing industry for its outstanding performance characteristics. It has thermal stability and storage period. The negative PS plate prepared by substituted diphenylamine diazo resin not only has good thermal stability, but also has a long storage period, which can meet the needs of long-term storage and transportation. PS Plate has photosensitive properties, and can complete the photosensitive and developing processes in a short time, improving printing efficiency. PS Plate also has good wear resistance and corrosion resistance, and can maintain stable performance in harsh printing environments.

PS Plate has a wide range of applications in the printing industry. It is widely used in the production of various printed materials such as newspapers, magazines, books, and packaging. During the printing process, PS Plate uses the hydrophilicity of the sand layer on the aluminum base and the ink-affinity properties of the photosensitive resin layer to achieve a balance between water and ink on the surface of the aluminum base. This state of balance ensures the stable quality of the printed product, bright colors, and clear images.

PS Plate is also suitable for various printing processes, including monochrome printing, multi-color printing, and color printing. In color printing, PS Plate can ensure accurate registration between color plates, thereby improving the overall quality of printed products. At the same time, PS Plate also has good adaptability and can be applied to various printing machines and printing materials to meet different printing needs.

As an innovator of printing technology and a powerful assistant for artistic creation, PS Plate has become an important part of modern printing and art fields with its unique performance and wide application fields. With the continuous advancement of science and technology and the continuous development of printing technology, the performance and application fields of PS Plate will be further expanded and improved. We have reason to believe that in the future printing and art fields, PS Plate will continue to play an important role and contribute to the advancement of printing technology and the prosperity of artistic creation.
