掌握宣传页印刷版面方向的方法
作者:admin 来源:http://www.sdhzyw.com 发布时间:2017-11-6 17:30:17 浏览次数:738

当今的单张纸印刷机对纸纤维的走向与输纸方向平行还是垂直已经不怎么在乎,所以,济南宣传页印刷只要晓得印刷版面的排版方式与纸纤维方向配合即可。

Today's sheet fed presses don't care much about the direction of the paper fiber and the direction or direction of the paper feed, so the printer only knows the layout of the printing page and the direction of the paper fiber.

卷筒纸印刷机的情况稍微复杂一点,输纸方向是无法改变的,所能掌握的只有版面安排的方向,使之尽可能考虑纸纤维的方向与书脊平行。

The printing machine case is a little more complex, the paper conveying direction can not be changed, the layout direction only can grasp, make it possible to consider the paper fiber direction parallel to the spine.

用单张纸数字印刷然后装订(胶订或者精装)的书,其书页外围常见“荷叶边”现象。这主要是因为纸张经过印刷机加热辊时,被快速烘干,引起纸张内部应力不均而造成的。其他原因有:印刷前纸张保存不当,纸的含水量过高;纸张在印刷和装订过程中受潮。纸纤维的走向与书脊的方向垂直也会引起此类问题。

Books printed with sheets of paper and bound (bound or bound) are often surrounded by "lotus leaves" on the outside of the pages. This is mainly due to the rapid drying of the paper through the heating roller of the printing press, resulting in uneven stress inside the paper. Other reasons are: the paper is poorly preserved before printing; the moisture content of the paper is too high; the paper is damp in the process of printing and binding. With the trend of paper fiber perpendicular to the direction of the spine can also cause such problems.

要避免这个问题,装订者必须与印刷者协调,在印刷和运往装订厂的过程中做好生产的跟踪纪录;创造比较稳定的、可以控制的环境条件。

In order to avoid this problem, the binder must coordinate with the printer in the process of printing and delivering to the binding factory to keep track of the production, and create relatively stable and controllable environmental conditions.

大多数单张纸数字印刷机使用墨粉,而不是传统的油墨。墨粉经过加热辊时受热熔化,墨色由此固着于纸面。热熔的过程中有少量溶剂释放,这类溶剂的量虽然很小,但是都吸附于纸面,对装订胶和纸的粘着性产生影响。

Most sheet fed digital presses use toner instead of traditional ink. Toner after heated roll heat melting, the ink on paper. In the process of hot melt, a small amount of solvent release, the amount of such solvents, although very small, but are adsorbed on the paper, the binding glue and paper adhesion impact.

装订的牢度有时与覆膜的牢度有关。数字印刷的书的封面往往是彩色的。因为印刷数量小,所以也采用彩色墨粉数字印刷机印制。墨粉对于涂布纸的粘着性较差,在书脊的转折处常常可见墨粉剥离。

The fastness of the binding is sometimes related to the fastness of the film. The cover of digital printed books is often colored. Because of the small number of printing, it is also printed with color toner digital printing machine. Toner for coated paper adhesion is poor, at the turning point of the spine is often visible toner stripping.

一般来说,这种短版业务不宜表面上光和覆膜,因为墨粉的表面粘着力较差,稍有折皱,塑膜与纸就会脱离。通常覆膜只用于以传统油墨印制的书籍封面,如果客户坚持要求,比较合理的做法是封面的外面单面覆膜。这样不至于引起书芯与封面的脱落。

Generally speaking, this kind of short service is not suitable for surface coating and laminating, because the surface adhesion of toner is poor, and there is a little wrinkle, the plastic film and paper will be divorced. Usually covered only for traditional ink printed book cover, if customers insist, the more reasonable way is to cover the outer surface of a single film. This will not cause the book core and cover fall off.

上述数字印刷品装订的问题有什么方法可以解决呢?

What is the solution to the problem of digital printing binding?

1.调节数字彩色印刷机的墨粉的热熔温度,使之达到更佳的粘着性。

1. adjust the hot melt temperature of toner for digital color printing machine to achieve the best adhesiveness.

2.选用适当的封面材料,现在封面材料有多种多样,试验并选用一种与墨粉亲和力更强的材料。通常这种材料已经做过表面处理,涂有专门吸附墨粉的表层。

2. select the appropriate cover material, now cover a variety of materials, test and choose one of the strongest affinity with toner material. Normally, this material has been treated with a surface, coated with a specially adsorbed toner.

3.对塑膜材料本身进行表面处理,改善它与墨粉的吸附性。

3. surface treatment of plastic film material to improve its adsorption capacity with toner.
