Book printing is the process of producing physical copies of written works, typically using a combination of text and images. This process can involve various techniques, such as offset printing, digital printing, or letterpress, depending on the scale and quality desired. The printed books are usually made from sheets of paper that are folded, bound, and trimmed to create a finished product. Publishing companies often oversee the printing process to ensure that the final product meets quality standards and is ready for distribution to bookstores and readers.
