In the actual printing of large background album, we often encounter the phenomenon of false printing. To solve this problem, we need to have some experience in this field. In the process of large background color brochures printing, summed up some of the solutions in this respect, the following Jinan album printing and you talk about the solution to this problem in detail.

首先我們會考慮到印刷壓力與紙張的問題，總認為壓力過小、紙張不好等，通常在調整印刷壓力無法解決問題的時候，只可以換紙，但這樣不但增加成本，而且延誤時間。下面我們通過調整印刷工藝的方法可以使這一問題得到根本的解決。大底色畫冊在實際印刷中常遇到印刷不實的現(xiàn)象，解決這類的問題需要在這方面有一定的經(jīng)驗。

First of all, we will consider the problem of printing pressure and paper. We always think that the pressure is too small and the paper is not good. Usually, when the problem cannot be solved by adjusting the printing pressure, we can only change the paper, but this will not only increase the cost but also delay the time. We can solve this problem by adjusting the printing process. In the actual printing of large background album, we often encounter the phenomenon of false printing.

在實際生產(chǎn)中常遇到30%～50%的紅版和100%藍版疊印的藍色實地，由于紙質不好常出現(xiàn)紅網(wǎng)發(fā)花，而改用紙質好的紙張問題便解決，非常明顯然這是紙張的原因。但也可以通過對工藝的調整解決這一問題.  經(jīng)過分析，由于四色機是濕濕疊印，在濕的實地上疊印另一色墨的時候，轉印的效果比較差，油墨轉移率低，試著將品紅和青的印刷色序調換，先印刷品紅網(wǎng)，這樣品紅網(wǎng)可100%向紙張轉印，轉印率達到高，而青版實地有一半以上的面積也可直接轉印在紙張上，這樣印出的印刷產(chǎn)品果然非常的平實，問題得到了根本的解決，即使換用質量差一點的紙張也可以印實了。

In the actual production, we often encounter 30% - 50% of the red and 100% of the blue overprint. Because the paper is not good, the red screen often appears, and the problem of using good paper is solved. Obviously, this is the reason for the paper. But this problem can also be solved by adjusting the process After analysis, because the four-color machine is wet and wet overprint, when overprint another color ink on the wet field, the transfer effect is relatively poor, and the ink transfer rate is low. Try to change the printing color sequence of magenta and cyan, print the magenta screen first, so that the magenta screen can be 100% transferred to the paper, the transfer rate is the highest, and more than half of the green field area can also be directly transferred on the paper The printed products produced by the sample printing are really plain, and the problem has been fundamentally solved. Even if the paper with poor quality can be printed.

膠版紙印刷畫冊封面，版面有大面積的藍色實地。印在銅版紙，效果非常的好，而膠版紙的時候發(fā)花現(xiàn)象比較嚴重。由于藍色在第二組，紙張親墨性比較差，與油墨結合不牢，印上的藍墨會在后兩組橡皮布上反剝下來一部分。于是我們調整了印刷色序，將藍版放在了后一組，印刷發(fā)花故障得到了排除。

Offset paper printing album cover, the page has a large area of blue field. Printed on coated paper, the effect is very good, and offset paper when the flower phenomenon is more serious. Due to the blue in the second group, the paper ink affinity is relatively poor, and the ink is not firmly combined, the blue ink printed on the latter two groups of blanket will peel off a part. So we adjusted the printing color sequence, put the blue plate in the last group, and the printing hairspray problem was eliminated.

濟南畫冊印刷通過以上兩個故障的排除，發(fā)現(xiàn)印刷色序對油墨轉移的影響非常的大，尤其是多色印刷濕濕疊印，根據(jù)不同的活件靈活調整印刷色序是非常必要的。

Jinan album printing through the above two troubleshooting, found that the printing color sequence has a great impact on the ink transfer, especially multi-color printing wet and wet overprint, it is very necessary to adjust the printing color sequence flexibly according to different moving parts.
