機組式柔印機上實現水墨印刷薄膜的注意事項!

環保的壓力加快了國內薄膜柔印水墨的研發與應用,柔印將在這個市場倒逼下迎來新的發展機遇。但濟南彩色乐天堂fun88体育提示大家,機組式柔印機械想要實現水墨印刷薄膜,在下面這幾個方面仍要做出改善!

The pressure of environmental protection has accelerated the development and application of domestic film flexo ink. Flexo printing will usher in new development opportunities under the pressure of this market. But Jinan color design printing prompts you that the unit flexo printing machine wants to achieve ink printing film, in the following aspects still need to be improved!

首先,由于沒有衛星式機型中調增大的風險,用機組式機型印薄膜是一個不錯的選擇。但國內的機組式柔印機大多印刷紙張,習慣了大張力條件下的調節,改換薄膜后張力控制的調節必須很細心,以前用手拍一下紙帶松緊就可判定張力大小的操作習慣,很可能不適應。

First of all, because there is no increase in the risk of satellite type adjustment, it is a good choice to use machine type printing film. However, most domestic flexo printers are used to adjusting under the condition of large tension. The adjustment of tension control after changing the film must be very careful. The operation habit of determining the tension size can be determined by patting the tape tightly before, which may not be suitable.

必須注意單位線張力概念。在極限條件下按滿幅寬度算出大或小單位線張力,然后根據所用薄膜的種類、厚薄以及寬度,算出放卷張力、進料張力、出料張力,以及收卷張力。這同凹印薄膜印刷很相似,觸類旁通。

We must pay attention to the concept of unit line tension. Under the limit condition, the tension of large or small unit line can be calculated according to the full width. Then, according to the type, thickness and width of the film used, the unwinding tension, feed tension, discharge tension and winding tension can be calculated. This is very similar to gravure film printing.

由于因環保要求使用水墨,很擔心薄膜水墨干燥比較慢,因此想把原先機組式柔印機的下走紙結構改為上走紙。這樣,烘道翻到機身之上,外形同凹印機很相似。這種改善是合理的,因為上走紙,整機的重心往下移,機器在高速運轉中更穩定。烘道也可加長,干燥效果更好。但是必須注意一條:當薄膜印刷后出烘道遇到的第一根轉角導輥,請注意表面磨擦系數,不能太粗糙。不然,水墨成膜尚未徹底固化,墨膜較嫩,過于粗糙的導輥表面,容易將墨膜拉傷。

Because of the requirement of environmental protection to use ink, I am worried about the slow drying of thin film ink, so I want to change the down paper structure of the original unit flexo press to up paper. In this way, the dryer runner turns over the fuselage, and the shape is very similar to gravure press. This improvement is reasonable, because when the paper is moved up, the center of gravity of the whole machine moves down, and the machine is more stable in high-speed operation. The drying path can also be lengthened, and the drying effect is better. But we must pay attention to one thing: when the first corner guide roller is encountered in the drying path after thin film printing, please pay attention to the surface friction coefficient, not too rough. Otherwise, ink film has not been completely cured, ink film is tender, too rough guide roller surface, easy to pull ink film.

機組式機型水墨印刷薄膜,可同凹印采用相同的薄膜。只要凹印能達到的套準精度,機組式柔印同樣能達到。因為這兩種機型的結構大同小異,對薄膜的張力控制要求相差不多。而且,由于柔印壓力比凹印壓力小許多,由正壓力造成的反向摩擦力也相差許多,柔印薄膜料卷的補償比凹印的更小許多,因此,凹印傳動與薄膜補償中的經驗數據,可能比柔印的數據要模糊得多。這是柔印的有利之處。但若一定要在機組式機型上印得比凹印更薄,這有一定難度。

Unit type ink printing film, can use the same film as gravure printing. As long as gravure printing can achieve the alignment accuracy, unit flexo printing can also achieve. Because the structures of the two models are similar, the requirements for tension control of thin films are similar. Moreover, because flexographic pressure is much lower than gravure pressure, the reverse friction caused by positive pressure is much different, and the compensation of flexographic film volume is much smaller than gravure printing, the empirical data of gravure transmission and film compensation may be much more ambiguous than that of flexographic printing. This is the advantage of flexo printing. But if you have to print thinner than gravure on the unit model, it will be difficult.
