There are two main forms of printing, one is traditional printing, which requires plate making and then printing. There are mainly lithographic printing (also known as offset printing), letterpress printing. Gravure printing, screen printing. The other is the printing under the recent high-tech support, called digital printing. A printing method that does not require direct inkjet printing. His advantage is that it shortens the printing time and saves costs without plate making. But now the printing quality of the main digital presses in the market is simply no way to compare with traditional printing.
