上机印刷制版工艺流程
    英文回答：
    Prepress Process Flow for Computer-to-Plate (CTP) Printing.
    1. File Preparation.
    Create or obtain high-resolution digital artwork.
    Ensure that the file meets the printing specifications (resolution, color mode, etc.).
    Convert the artwork into a PostScript (PS) or Portable Document Format (PDF) file.
    2. Raster Image Processing (RIP)。
    RIP software converts the digital file into a bitmap image (raster image).
    The raster image consists of a grid of tiny dots, which are the basic building blocks of the printed image.
    RIP settings determine the resolution, screening, and other image parameters.
    3. Plate Imaging.
    The CtP system images the raster image onto a printing plate.
    The plate is coated with a light-sensitive emulsion that reacts to the UV light emitted by the CTP machine.
    The exposed areas of the plate become hardened, while the unexposed areas remain soft.
    4. Plate Processing.
    The plate is developed to remove the unexposed emulsion.
    This creates the printing image on the plate, where the hardened emulsion represents the printed areas.
    5. Plate Mounting.
    The plate is mounted on the printing press.
    The plate is aligned and secured to ensure accurate registration during printing.

    6. Printing.
    Ink is transferred from the printing plate to a blanket roller.
    The blanket roller then transfers the ink to the paper or other substrate.
    The printed sheets are collected and dried.
