彩色印刷该留意些什么？彩色印刷不只是单纯性的正常情况下4色的进行印刷,有很多海外的消费者他们期刊杂志上常常会出现各种各样专色撞出来的颜色,非常是有一类品红颜色,这一个颜色是不好调的,另外许多 消费者会使用到专色,或是进行印刷完过水油,在彩色的基础上增多黑印刷油墨的数量，始终不变混合色的颜色，包装盒厂家在降低颜色明度的同时也使彩度降低，一般来说，在四色印刷的技术中，图片的颜色是需要留意的一个问题了，因此，包装盒厂家务必对四色印刷中的颜色问题多方面高度重视。
What should we pay attention to in color printing? Color printing is not just a simple four color printing under normal circumstances. Many overseas consumers often have a variety of spot colors on their magazines. There is a kind of magenta color, which is not easy to adjust. In addition, many consumers will use spot colors, or after printing with water and oil, increase the number of black printing inks on the basis of color, and keep the color of mixed colors unchanged, Packaging box manufacturers can reduce the brightness of color as well as the chroma. Generally speaking, in the four-color printing technology, the color of pictures is a problem that needs attention. Therefore, packaging box manufacturers must attach great importance to the color problem in four-color printing in many aspects.
这一个彩色设计要非常的留意下面四个方面：
This color design should pay attention to the following four aspects:
01掏空
01 Emptying
黄色底板上压有一行蓝色字，那样包装盒厂家在该菲林的黄色版上，蓝色字所处具体位置就务必为空。反之蓝版亦然。否则蓝色的东西直接印在黄色上，颜色会造成发生变化，原本蓝色的字变成了绿色。
A line of blue words is pressed on the yellow base plate, so that the specific position of the blue words on the yellow version of the film by the packaging box manufacturer must be empty. The blue version is the same. Otherwise, the blue things will be directly printed on the yellow, and the color will change, and the original blue words will become green.
02叠印
02 Overprint
某红色底板上压有一行黑灰色字，那样包装盒厂家在该菲林的红色版上，黑灰色字所处具体位置也就不需要掏空。因黑灰色可压着任何色，若将黑灰色具体内容掏空，非常是一部分较小的文字内容，进行印刷时有点儿有误差值便会造成外露白边，而黑白色反差的对比又比较大，非常容易看得见。
A line of black and gray words is pressed on a red base plate, so that the packaging box manufacturer does not need to empty the specific position of the black and gray words on the red version of the film. Because black gray can be pressed against any color, if the specific content of black gray is hollowed out, it is a very small part of text content. When printing, there is a little error value, which will cause exposed white edges, and the contrast between black and white color is relatively large, which is very easy to see.
03四色黑
03 Four color black
这也是相对比较比较常见的相关问题。包装盒厂家内容输出前有必要常规检查出版发行文件格式内黑色的文字内容，尤其是是小字，会不会仅有黑板上面有，而在其余三色版上不应该发生。假如如现，则印刷出来的成品质量会打一折扣，RGB平面图形转化成CMYK平面图形时，黑色的文字内容一定会会转换成四色黑。除非说特殊的设定，不然就有必要将其处理一下，才可内容输出菲林。
This is also a relatively common problem. Before the content output of the packaging box manufacturer, it is necessary to regularly check whether the black text content in the format of the published document, especially the small characters, can only be found on the blackboard, and should not occur on the other three color versions. If so, the quality of the printed products will be discounted. When RGB graphic is converted to CMYK graphic, the black text will be converted to four color black. Except for special settings, it is necessary to handle them before content can be output to film.
04图像为RGB模式
04 Image in RGB mode
RGB模式的图像内容输出时，RIP软件系统一般的都能自动的将其转化成为CMYK基本模式内容输出。但其色相质量会大打折扣，包装盒厂家印出的成品色相淡，不明亮，实际效果很不大好。图像合适在photoshop内将其转化成为CMYK基本模式，若为扫描仪稿件，那样还有必要通过校色这一种工艺流程，图像才可应用。很多朋友在PS里面做文件格式的时候不会在意RGB和CMYK的格式。
When RGB mode image content is output, RIP software system can generally automatically convert it into CMYK basic mode content output. However, its hue quality will be greatly reduced. The finished products printed by the packaging box manufacturer are light and not bright, and the actual effect is not very good. The image is suitable to be converted into the CMYK basic mode in Photoshop. If it is a scanner manuscript, it is necessary to use the color correction process to apply the image. Many friends don't care about RGB and CMYK formats when they do file formats in PS.
包装与纸质印刷品的文件处理是非常非常重要的，因为色彩印刷是印刷品加工过程的一步，这是不能出错的，如今的包装盒厂家现在的设备都比以前更加，可以大大避免这类问题的出现。
The document processing of packaging and paper printed materials is very important, because color printing is a step in the processing of printed materials, which cannot be wrong. Today's packaging box manufacturers have more advanced equipment than before, which can greatly avoid such problems.
