纸张和油墨(国外英文资料) The selection of materials in the printing process will affect the two aspects of the printed images artistic effect and technical performance, and also affect the stability of the quality of the printed image. In addition, the performance of raw materials will also affect production efficiency. Printing production is bound to require the use of a variety of materials, good quality of the materials used, is to ensure the establishment of high-quality operating processes indispensable conditions. Many kinds of materials used in the printing process, including paper, ink, glue, rubber blanket, inking oil, the influence on the printing quality is mainly the larger paper and ink. First, the influence of paper performance on printing quality The printing performance of paper determines whether the printing process can be carried out smoothly and whether high-quality printing can be obtained.
