Abstract：In the actual production of the pre-press Plate-making, there are various hardware and software, such as scanners, computers, monitors, inkjet printers, imagesetter, scanning software, Photoshop, Pagemaker, etc. When hardware running and software being operated ,the influence of any kind of illegal operation on the final image quality are self-convident:result in rework and cost increase. Generally speaking,the Pre-press Plate-making sector of the enterprises controls the quality of the image by Process-units lack of a comprehensive,integrated solution. For example, when print color deviation appears, it may be necessary that scanning department solve the problem with proofing department or more departments,otherwise the problem will not be able to completely resolved rapidly.Therefore, the quality control of prepress image processing is a comprehensive task. What this article discusses is that control the quality of Pre-press image through scanning, color correction, output device calibration, Pre-press equipment color management.
