来源:http://www.xinfengyinshua.cn/   发布时间:2020-11-27
大底色画册在实际印刷中常遇到印刷不实的现象,解决这类的问题需要在这方面有一定的经验。在大底色宣传册印刷过程中总结了一些这方面的解决方案,下面济南画册印刷和大家详细聊聊这个问题的解决方法。
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.
首先我们会考虑到印刷压力与纸张的问题,总认为压力过小、纸张不好等,通常在调整印刷压力无法解决问题的时候,只可以换纸,但这样不但增加成本,而且延误时间。下面我们通过调整印刷工艺的方法可以使这一问题得到根本的解决。大底色画册在实际印刷中常遇到印刷不实的现象,解决这类的问题需要在这方面有一定的经验。
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.

在实际生产中常遇到30%~50%的红版和100%蓝版叠印的蓝色实地,由于纸质不好常出现红网发花,而改用纸质好的纸张问题便解决,非常明显然这是纸张的原因。但也可以通过对工艺的调整解决这一问题.  经过分析,由于四色机是湿湿叠印,在湿的实地上叠印另一色墨的时候,转印的效果比较差,油墨转移率低,试着将品红和青的印刷色序调换,先印刷品红网,这样品红网可100%向纸张转印,转印率达到最高,而青版实地有一半以上的面积也可直接转印在纸张上,这样印出的印刷产品果然非常的平实,问题得到了根本的解决,即使换用质量差一点的纸张也可以印实了。
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.
胶版纸印刷画册封面,版面有大面积的蓝色实地。印在铜版纸,效果非常的好,而胶版纸的时候发花现象比较严重。由于蓝色在第二组,纸张亲墨性比较差,与油墨结合不牢,印上的蓝墨会在后两组橡皮布上反剥下来一部分。于是我们调整了印刷色序,将蓝版放在了最后一组,印刷发花故障得到了排除。
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.
济南画册印刷通过以上两个故障的排除,发现印刷色序对油墨转移的影响非常的大,尤其是多色印刷湿湿叠印,根据不同的活件灵活调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.
