What is the difference between modern printing and traditional printing?

Now it is offset printing. Traditionally, film is made, and the forms of document production are different. Now offset printing is CTP publishing, which is convenient, good quality and high efficiency. In terms of printing color, modern printing technology ensures that the printing color meets the requirements through color management system inspection, while traditional printing technology can't guarantee it, so it can only be judged by manual experience, so the printing effect can't be guaranteed.
