影响印刷效果还和其版式的选取有关系

  陷印是一项复杂的专业印前处理技术。在印刷中如果各快印版套印完全准确的话,那么文字、图形和图像相互结合时,在不同颜色相交接时就可能会露出底色,即“露白”,在实际生产中难免出现套准偏差(套印允许公差为0.1mm),即在印刷品上出现没有着墨的“露白”现象。

Trapping is a complex professional prepress technology. If the print version in the printing overprint completely accurate words, then the text, graphics and image combination, in different colors may intersect connection will reveal the background, namely "white", in the actual production will inevitably lead to the deviation of registration (Registration tolerance 0.1mm), which is in print does not appear most "white" phenomenon.

为防止印刷后“露白”,在印前要做陷印的预处理。陷印的原理是:在颜色交界处将浅色的一方向深色的一方扩张。无论是图像还是图形,只要有明显的两色交界,就可能需作陷印处理。印前的陷印处理会丢失图文细节,使之模糊,处理不好还会导致非常糟糕的结果,所以作为设计者应注意以下几点:

In order to prevent the "white", printed in the prepress to do pretreatment trapping. The trapping principle is: the color at the junction will be a direction of the dark light on one side of the expansion. Both images and graphics, as long as there is at the junction of obvious white, may be required for the trapping process. The trapping process will lose prepress graphic details, make fuzzy processing not good will result in very bad results, so the designer should pay attention to the following points:
通常可给文字加上小小的白边,要避免使用很小的浅色文宇(陷印会使之模糊不清),选用深色文字图案压印于浅色连续变化的背景上是较好的选择,这样绝对不会露白,但要注意不可大面积压印,大面积的压印会增加墨量,导致印刷过程中粘连、起脏,影响印刷效果甚至难以印刷。
Usually can give a small text and white edge, to avoid the use of very small light Wen Yu (trapping makes blurred), use dark text on light colored pattern autogram continuous changes in the background is a good choice, so absolutely not the thief, but be careful not to pressure a large area of India, a large area will imprint increase the amount of ink, resulting in dirty adhesion, printing process, printing effect is even more difficult to print effect.
在印刷类平面设计中,分辨率的设置必须根据设计和印刷工艺的要求,特别是印刷所用的承印材料(多为纸张)等多种因素来确定,并不是任何图片都一定要调到最高分辨率。如报纸印刷的网线比精美画册要低,它们对图像文件的分辨率的要求也不一样。
In printing graphic design, the setting of resolution must be determined according to the requirements of design and printing process, especially those of printing materials (mostly paper) and so on. Not all pictures must be transferred to the highest resolution. For example, the network lines printed in the newspaper are lower than the beautiful picture books, and they require different resolution of the image files.
如果将用新闻纸印刷的报纸上的图片分辨率调至与用铜版纸印刷的画册相同的分辨率,不仅毫无意义,反而导致印刷糊版。印刷类电脑平面设计中对不同对象的分辨率的设置如下:
If the resolution of the newspaper printed on newsprint is transferred to the same resolution as the printed picture book printed with coated paper, it will not only meaningless, but lead to printing paste version. In print computer graphic design, the resolution of different objects is set as follows:
印刷平面设计的尺寸,特别是偏大偏小及异形的包装装潢印刷品的尺寸,在印刷工艺上受到种种客观因素的限制。
The size of printing graphic design, especially the size of large and small package printing and printing, is limited by various objective factors in printing process.
