棋牌游戏平台-威尼斯官方网站平台-登录印刷实地不实问题的解决方法?

来源:   日期:2020-12-30

大底色棋牌游戏平台-威尼斯官方网站平台-登录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。小编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,下面和大家详细聊聊这个问题的解决方法。

In the actual printing of large background color picture album, we often encounter the phenomenon of false printing. To solve this kind of problem, we need to have some experience in this aspect. Xiaobian summed up some solutions in the printing process of large background color brochures. Let's talk about the solutions to this problem in detail.
首先大家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。下面大家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。
First of all, we will consider the problems of printing pressure and paper. We always think that the pressure is too low and the paper is not good. Usually when the problem can not 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. Now we can solve this problem by adjusting the printing process.
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。
In the actual production, we often encounter 30% - 50% of the red version and 100% of the blue version of the overprint blue field, because the paper is not good, often appear red net hair, and change to paper good paper problem will be solved, obviously this is the reason for the paper. But this problem can also be solved by adjusting the process.

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,转印率达到很高,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。
After analysis, due to the four-color machine is wet overprint, in wet field overprint another color ink, the transfer effect is poor, ink transfer rate is low, try to magenta and cyan printing color order exchange, first print magenta screen, so magenta screen can be 100% to paper transfer, transfer rate is very high, and green version of the field has more than half of the area can also be directly transferred on paper, this is very important The printed products produced by the sample printing are really flat, and the problem has been fundamentally solved. Even if the paper with poor quality is used, it can be printed.
胶版纸印刷棋牌游戏平台-威尼斯官方网站平台-登录封面,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。于是大家调整了印刷色序,将蓝版放在了后一组,印刷发花故障得到了排除。
Offset paper printing album cover, the layout has a large area of blue field. Printed on coated paper, the effect is very good, and offset paper when the phenomenon is more serious. Due to the blue in the second group, the ink affinity of the paper is relatively poor, and the ink is not firmly combined, the blue ink on the latter two groups of blanket will be peeled off. So we adjusted the printing color sequence, put the blue plate in the latter group, and the printing problem was eliminated.
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。
Through the above two troubleshooting, it is found that the printing color sequence has a great impact on ink transfer, especially for multi-color printing wet overprint. It is necessary to adjust the printing color sequence flexibly according to different live parts.
