In color printing, there are many factors will affect the quality of printed matter, resulting in a lot of printed matter production is not optimistic, in which overprint is one of the main factors affecting the quality of printed matter. However, many factors in the printing process will affect the overprint. Therefore, in the process of printing, we should pay attention to the two points on the paper and plate

一、纸张外表越粗糙，油墨的吸收量就越大。打印纸的粗糙外表，油墨泛滥现象更容易出现。这是因为有些纸张纤维的交织发生的间隙，均匀的涂层还没有很好的覆盖。这种压纹纸和印版时，油墨层外表发生不良接触。如果通过适当的印刷压力，可以有足够的接触时间与油墨层的布局的纸张的平滑性差，实现均匀的压印接触，可以确保印刷墨层均匀平服。

1、 The rougher the surface of the paper, the more ink absorption. Printing paper rough appearance, ink flooding phenomenon is more likely to occur. This is because some paper fibers interweave the gap, uniform coating has not been well covered. This kind of embossing paper and printing plate, ink layer surface bad contact. If through the appropriate printing pressure, can have enough contact time and ink layer layout of the paper smoothness is poor, to achieve uniform imprint contact, can ensure that the printing ink layer is uniform.

二、保守胶合板面前底部支架的印刷版，不只有许多弊端，容易呈现油墨转移不良现象，引起油墨布局不均的发生。这是因为木材的底部托盘不够强，变形的可能性也比较大，导致不稳定的印刷压力，油墨层的布局不能均匀地转印到纸张上。比较好的方法就是做好备份操作技术，一些印刷板面积较大，应选择一些平整度好，比拟扎实的金属版本的护理，可以更好的防止这些现象的发生。

2、 The printing plate with the bottom bracket in front of the plywood has many disadvantages, such as poor ink transfer and uneven ink layout. This is because the bottom of the wood tray is not strong enough, the possibility of deformation is also relatively large, leading to unstable printing pressure, the layout of the ink layer can not be evenly transferred to the paper. A better way is to do a good job of backup operation technology, some printed board area is larger, should choose some good flatness, compared with solid metal version of care, can better prevent the occurrence of these phenomena.

                                       

彩色印刷品在设计和叠印的处理上要注意以下六点：

The following six points should be paid attention to in the design and overprint of color printed matter

1、字形过小的文字应避免选择笔画太细的字体，比如仿宋体、细圆体等，字体的笔画原本就细，如果字形过小，印刷时笔画就容易丢失，导致字迹不全；

1. If the font size is too small, you should avoid choosing the font with too thin strokes, such as song style, thin circle style, etc. the strokes of the font are originally thin. If the font size is too small, the strokes are easy to be lost during printing, resulting in incomplete handwriting;

2、尤其是细小的文字，应避免使用多色套印；

2. Especially for small words, multi-color overprint should be avoided;

3、尽量避免使用细小的反白文字；

3. Try to avoid using small negative words;

4、细小的文字应避免叠印在深色的背景上；

4. Small text should avoid overprint on dark background;

5、细小的文字应避免使用金墨、银墨印刷，金墨、银墨的颗粒比一般油墨粗，用于印刷细小的文字时，容易导致字迹模糊等问题；

5. Gold ink and silver ink should be avoided for small words. The particles of gold ink and silver ink are thicker than ordinary ink. When used for printing small words, it is easy to cause problems such as illegibility;

6、尽可能采用叠印方式在底色上印文字和图片，而不用在底色版上挖空的方式。

6. Try to use the overprint method to print text and pictures on the background, instead of digging in the background.

在彩色印刷品设计印制时注意这些问题，可防止后面发生很多不必要的浪费，还可呈现给客户精美的印品，何乐而不为呢。希望以上内容对您有所帮助，如您想了解更多精彩内容请点击我们的官网：济南彩色设计印刷https://www.sdhzyw.com 。
