Album printing is an issue we have been discussing all the time. There is no 100% in printing Print as like as two peas, printing is a reproduction process. In this process, we will keep trying to keep the color saturation close to the original. Printing is closely related to design, documents, colors and different batches of paper. So how we should solve and deal with this problem after the color problem is concerned. Questions.

，画册印刷的颜色的色差评价结果在主观，客观上的不一致性有两个方面，一个是当同一颜色朝不同的颜色方向偏移产生相同的色差值时，我们的人眼就能感觉到颜色差别的不同，二是不同的颜色朝同一颜色方向偏移产生相同的色差时，人眼能感觉到的颜色的差别程度也不同。

First of all, there are two subjective and objective inconsistencies in the color difference evaluation results of picture album printing. One is that when the same color deviates towards different color directions and produces the same color difference value, our eyes can feel the difference of color difference. The other is that when different colors deviate towards the same color direction and produces the same color difference, our eyes can feel the difference of color The degree of difference is also different.

颜色的属性，各种物体对光会产生的三种不同的作用，对光的吸收，透射和反射，之所以物体会呈现色彩，是由该物体对光作了选择性吸收的结果，从颜色的特性上可以把颜色分为两类：消色和彩色，消色由黑色、白色和不同深浅的灰色组成。彩色是除消色之外的所有颜色如红色、蓝色绿色等。

The attribute of color, the three different effects of various objects on light, the absorption, transmission and reflection of light, the reason why an object appears color, is the result of the object's selective absorption of light. From the characteristics of color, color can be divided into two categories: achromatic and color. Achromatic is composed of black, white and different shades of gray. Color is all colors except achromatic, such as red, blue, green, etc.

画册印刷在上机印刷前，我们都是要经过设计颜色调整，一般经过数码打样，上机打样两种方式来确定画册印刷的颜色，在设计文件时多数以CMYK值先固定它的颜色，一般电脑屏幕上显示的色彩是不准确的，以数码打样和上机打样为准。

Before printing, we all need to adjust the design color. Generally, we use digital proofing and computer proofing to determine the color of album printing. When designing documents, most of them use CMYK value to fix its color first. Generally, the color displayed on the computer screen is inaccurate, and the digital proofing and computer proofing shall prevail.

在印刷过程当中很容易出现偏色的情况，颜色跟原稿有点不符合，印刷机长除了要找文件的原因之外，还要看是否是墨路的问题，文件是否在打样之后有所改动等等，是否要考虑还机器印刷等等原因。

In the printing process, it's easy to have color deviation. The color is a little inconsistent with the original. In addition to the reason why the printer commander wants to find the document, he also needs to see whether it is the problem of ink path, whether the document has been changed after proofing, and whether he needs to consider the machine printing and so on.

印刷中车速快慢也会影响画册的颜色深浅，这是车速的快慢会影响水墨的平衡状态。快车印版的水份及慢车印版上的水份量变化不一样，快车印版水份发挥小，慢车印版水份发挥大，由于水份的大小变化导致水墨失衡，那么必然会引起油墨的颜色变化，所以在印刷的时候也是要控制印刷车速，不能一会慢，一会快，这样印刷出来的印刷品肯定是有色差的。

In printing, the speed of the car will also affect the color of the album, which is the speed of the car will affect the balance of ink. The change of water content on the fast plate is different from that on the slow plate. The water content on the fast plate is small while that on the slow plate is large. Due to the imbalance of water and ink caused by the change of water content, the color of the ink will inevitably change. Therefore, the printing speed should be controlled when printing. It can't be slow or fast for a while, so the printed products must have some advantages Color difference.

导致画册印刷颜色色差有很多种，处理方法和控制方法也不止以上这些，印刷也是也结合实际经验和文件在印刷操作中不断探索、 摸索、积累经验，要每次知道错误的地方，做好笔记，提升自身能力外，也可以赢得更多的客户的信赖，更好做好自己的和服务。

There are many kinds of color difference in picture book printing, and the processing and control methods are not only the above. Printing is also combined with practical experience and documents to continuously explore, explore and accumulate experience in the printing operation. We should know the wrong place every time, take notes, improve our ability, and win more customers' trust, so as to better do our own brand and service.
