Seven, printing pressure
Printing pressure is an important factor in the transfer of ink during the printing process. The appropriate printing pressure in the printing process of books and periodicals prints the printed pages, texts and patterns clearly and cleanly, and the characters are not deformed and the ink is uniform and reliable. In the printing process, according to the quality of the paper used for the publication, the rubber roller and the padding material of the printing plate should be properly and reasonably selected, and the pressure between the three rollers should be properly adjusted. This is neither too large nor too light, ensuring the most appropriate Good pressure, so that the book printing process is always in the best state of uniform ink transfer.
