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.

，畫冊印刷的顏色的色差評價(jià)結(jié)果在主觀，客觀上的不一致性有兩個(gè)方面，一個(gè)是當(dāng)同一顏色朝不同的顏色方向偏移產(chǎn)生相同的色差值時(shí)，我們的人眼就能感覺到顏色差別的不同，二是不同的顏色朝同一顏色方向偏移產(chǎn)生相同的色差時(shí)，人眼能感覺到的顏色的差別程度也不同。

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.

顏色的屬性，各種物體對光會產(chǎn)生的三種不同的作用，對光的吸收，透射和反射，之所以物體會呈現(xiàn)色彩，是由該物體對光作了選擇性吸收的結(jié)果，從顏色的特性上可以把顏色分為兩類：消色和彩色，消色由黑色、白色和不同深淺的灰色組成。彩色是除消色之外的所有顏色如紅色、藍(lán)色綠色等。

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.

畫冊印刷在上機(jī)印刷前，我們都是要經(jīng)過設(shè)計(jì)顏色調(diào)整，一般經(jīng)過數(shù)碼打樣，上機(jī)打樣兩種方式來確定畫冊印刷的顏色，在設(shè)計(jì)文件時(shí)多數(shù)以CMYK值先固定它的顏色，一般電腦屏幕上顯示的色彩是不準(zhǔn)確的，以數(shù)碼打樣和上機(jī)打樣為準(zhǔn)。

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.

在印刷過程當(dāng)中很容易出現(xiàn)偏色的情況，顏色跟原稿有點(diǎn)不符合，印刷機(jī)長除了要找文件的原因之外，還要看是否是墨路的問題，文件是否在打樣之后有所改動(dòng)等等，是否要考慮還機(jī)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.

印刷中車速快慢也會影響畫冊的顏色深淺，這是車速的快慢會影響水墨的平衡狀態(tài)?？燔囉“娴乃菁奥囉“嫔系乃萘孔兓灰粯?，快車印版水份發(fā)揮小，慢車印版水份發(fā)揮大，由于水份的大小變化導(dǎo)致水墨失衡，那么必然會引起油墨的顏色變化，所以在印刷的時(shí)候也是要控制印刷車速，不能一會慢，一會快，這樣印刷出來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.

導(dǎo)致畫冊印刷顏色色差有很多種，處理方法和控制方法也不止以上這些，印刷也是也結(jié)合實(shí)際經(jīng)驗(yàn)和文件在印刷操作中不斷探索、 摸索、積累經(jīng)驗(yàn)，要每次知道錯(cuò)誤的地方，做好筆記，提升自身能力外，也可以贏得更多的客戶的信賴，更好做好自己的和服務(wù)。

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.
