1. Design layout: A professional design team conducts overall design based on the book manuscript, images, text content, brand elements, etc. provided by the client, combined with book positioning, format size, and binding method, including cover design, inner page layout design, graphic and textual layout, color matching, etc., to ensure that the book style is unified, visually beautiful, and in line with reading habits. At the same time, professional design software such as Adobe InDesign and Illustrator are used for file processing, checking parameters such as text layout, image resolution (not less than 300dpi), color mode, and bleed position (3mm) to ensure that the design meets printing standards.
2. Plate making: The designed file is directly transferred to the printing plate through CTP (Computer to Plate) technology, and the plate making materials mainly include PS plate (pre coated photosensitive plate), CTP plate, etc. Strictly control parameters such as dot restoration and registration accuracy during the plate making process to ensure the quality of the printing plate and provide a high-quality foundation for subsequent printing.
