[0003] The basic workflow of CTP technology is to generate a printing file from a computer, usually in PDF format, which contains the image, text and other design elements to be printed. Using professional image processing software, the digital file is processed to ensure image quality and printing effect. The processed digital file is directly exposed to the printing plate by CTP equipment. CTP equipment usually uses laser technology to transfer the image to the printing plate of photosensitive material. After exposure, the printing plate is developed, and the part not exposed by laser is removed to form the image part that can be used for printing. The developed plate needs to be cleaned and dried to ensure the plate surface is clean and ready for printing.
