在我们的印刷中，印刷的工序有很多，要印刷出一个好的印刷品，须每个工序都不出现问题才行。您知道济南画册印刷之前会有什么质量影响存在吗？

In our printing, there are many printing processes. To print a good print, each process must have no problems. Do you know what quality impact will exist before the printing of Jinan album?

原稿质量和用色水平是制约印刷质量的重要因素。在彩色原稿的选用和用色、配色上，是否满足制版印刷要求，已成为影响总体印刷质量的主要因素。特别是照片，忽视印刷制版要求，直接影响印刷整体质量。

Original quality and color level are important factors that restrict printing quality. Whether the selection, use and matching of color originals meet the requirements of plate making and printing has become the main factor affecting the overall printing quality. Especially for photos, ignoring the requirements of printing and plate making will directly affect the overall quality of printing.

图片是画龙点晴之笔，色彩鲜艳、层次丰富、清晰逼真的图片，给读者以美的享受。很难想象，一组偏色严重、缺少阶调层次、发虚变形的原稿，会印出美妙的效果。

The picture is a brush to draw the finishing touches. It is colorful, rich in layers, clear and lifelike, giving readers a beautiful enjoyment. It is hard to imagine that a group of originals with serious color deviation, lack of tonal levels, and false deformation will produce wonderful effects.

质量差的原稿，虽然可以处理，但要明确一点的是，图片信息只能在原稿的基础上去拾取信息，而不能再造信息。每一次调整都会损失大量层次、颜色信息。这项工作的基本原则是：忠实于原稿，高于原稿并力求风格统一。

Although poor quality originals can be processed, it should be clear that image information can only be picked up on the basis of the original, and information cannot be reproduced. Each adjustment will lose a lot of hierarchy and color information. The basic principle of this work is: be faithful to the original, be higher than the original and strive for unity of style.

在图片处理过程中主要要掌握以下几点：

The following points should be mastered in the process of image processing:

①图片层次的调整。

① Adjustment of picture hierarchy.

②校色，校色在于再现原稿所反映的(而非原稿本身)色彩。

② Color calibration, color calibration is to reproduce the color reflected by the original (not the original itself).

③RGBCMYK格式的转换，印刷出片所用的图片格式为CMYK格式。

③ RGB to CMYK format conversion, the picture format used for printing is CMYK format.

④锐化，锐化是提高图像清晰度的有效手段。

④ Sharpening, sharpening is an effective means to improve image clarity.
