彩色设计印刷是一个很笼统的概念，包括画册印刷，样本印刷，商务印刷，包装印刷，只要是在印刷当中都会出现一些质量的问题，油墨，纸张，压力，在印刷当中露白也是经常出现的一个质量问题，我们要怎么避免在印刷当中出现露白的情况，该如何对症下药解决这个影响因素的质量问题。
Color design printing is a very general concept, including album printing, sample printing, business printing, packaging printing, as long as there are some quality problems in printing, ink, paper, pressure, white in printing is also a common quality problem, how can we avoid white in printing, how can we find the right solution Solve the quality problem of this influencing factor.
在彩色设计印刷当中印刷露白是瓦楞纸箱生产中常见也是难以杜绝的质量问题。印刷露白严重影响印刷效果，不仅会造成纸箱表面印刷不美观，而且如果大面积出现露白，还会被视为不合格品，造成生产上的浪费。
In the process of color design printing, white printing is a common and difficult quality problem in the production of corrugated boxes. The printing white seriously affects the printing effect, not only will cause the carton surface printing is not beautiful, but also if a large area of white, it will be regarded as unqualified products, resulting in waste in production.
纸张吸水性、油墨粘度、印刷压力等都会造成印刷露白
Paper water absorption, ink viscosity, printing pressure, etc. will cause printing white
引发印刷露白现象发生的原因多种多样，如纸张吸水性，油墨粘度，印刷压力、纸板上有纸屑、灰尘等等。当然，引发印刷露白的原因不同，那么解决问题的方式自然也不尽相同！
There are many reasons for the phenomenon of printing whiteness, such as paper water absorption, ink viscosity, printing pressure, paper scraps and dust on the paperboard, etc. Of course, different reasons lead to printing exposure, so the way to solve the problem is not the same!
不同印刷露白的表现不同，应对症下药！
The performance of different printing whiteness is different, the medicine should be applied to the disease!
做为印刷人员，如何快速找到印刷露白的解决方向呢？往往造成印刷露白的原因不同，出现的露白也有细微的不同，印刷人员需要学会根据表象去判断造成印刷露白的症结所在，从而快速处理！我们大致可以从下面三个方面来看看。
As a printer, how to quickly find the solution to the problem of printing whiteness? The reasons for printing whiteness are often different, and the whiteness is also slightly different. Printers need to learn to judge the crux of printing whiteness according to the appearance, so as to deal with it quickly! We can look at it from the following three aspects.

1、先检测未印刷的纸板厚度值，再检查纸板从送纸单元出来后的纸板厚度值，看纸板是否有被送纸轮压溃。如果压溃了先解决纸板压溃的问题，送纸间隙是纸板厚度-0.3mm。
First check the thickness of unprinted paperboard, and then check the thickness of the paperboard after it comes out of the paper feeding unit to see if the paperboard is crushed by the paper feeding wheel. If the problem is solved first, the feeding gap is - 0.3mm.
2、以上都无误再增加印刷压力值，压力值不应过大，过大容易产生印刷煳，印刷慢磨损加快。
2. If all of the above are correct, increase the printing pressure value again. The pressure value should not be too large, which is easy to cause printing burn and slow printing wear.
3、检查印刷版压是否正常，可以查看印刷版面是否有足够的油墨量。印刷版硬度实地版适合在34-36度。
3. Check whether the printing plate pressure is normal, you can check whether the printing plate has enough ink. The hardness of printing plate is 34-36 degrees.
如果印刷油墨粘度正确，印刷版、网纹辊良好还是出现印刷露白现象，主要调整方向以油墨工艺为引导，印刷压力切勿一直加大，可以继续提高油墨粘度，及油墨的渗透性，也可以将印刷机调整为隔张送纸状态进行印刷。
If the printing ink viscosity is correct, the printing plate and anilox roller are good or the printing is exposed, the main adjustment direction is guided by the ink process, and the printing pressure should not be increased all the time. You can continue to improve the ink viscosity and the ink permeability, and you can also adjust the printing machine to the sheet fed state for printing.
做好印前的准备印刷版使用久了或印刷版面油墨污垢过多，就会降低印刷版的油墨转移量，当油墨转移量降低后，印刷露白现象就会经常发生。
Make good preparation before printing. If the printing plate is used for a long time or there is too much ink dirt on the printing plate, the amount of ink transfer will be reduced. When the amount of ink transfer is reduced, the phenomenon of printing whiteness will often occur.
总之影响印刷露白的情况很多，印刷人员也会往当中加水，使油墨的粘度偏低，也会造成露白的情况，印刷露白可能远远不止以上这些问题，我们一边学习，一边摸索。
In short, there are many problems affecting the printing whiteness. The printing staff will also add water to the printing ink to make the viscosity of the ink low, which will also cause the whiteness. The printing whiteness may be far more than the above problems. We are learning and exploring at the same time.
