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、紙張外表越粗糙，油墨的吸收量就越大。打印紙的粗糙外表，油墨泛濫現象更容易出現。這是因為有些紙張纖維的交織發生的間隙，均勻的涂層還沒有很好的覆蓋。這種壓紋紙和印版時，油墨層外表發生不良接觸。如果通過適當的印刷壓力，可以有足夠的接觸時間與油墨層的布局的紙張的平滑性差，實現均勻的壓印接觸，可以確保印刷墨層均勻平服。

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、保守膠合板面前底部支架的印刷版，不只有許多弊端，容易呈現油墨轉移不良現象，引起油墨布局不均的發生。這是因為木材的底部托盤不夠強，變形的可能性也比較大，導致不穩定的印刷壓力，油墨層的布局不能均勻地轉印到紙張上。比較好的方法就是做好備份操作技術，一些印刷板面積較大，應選擇一些平整度好，比擬扎實的金屬版本的護理，可以更好的防止這些現象的發生。

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.

                                       

彩色印刷品在設計和疊印的處理上要注意以下六點：

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

1、字形過小的文字應避免選擇筆畫太細的字體，比如仿宋體、細圓體等，字體的筆畫原本就細，如果字形過小，印刷時筆畫就容易丟失，導致字跡不全；

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、尤其是細小的文字，應避免使用多色套印；

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

3、盡量避免使用細小的反白文字；

3. Try to avoid using small negative words;

4、細小的文字應避免疊印在深色的背景上；

4. Small text should avoid overprint on dark background;

5、細小的文字應避免使用金墨、銀墨印刷，金墨、銀墨的顆粒比一般油墨粗，用于印刷細小的文字時，容易導致字跡模糊等問題；

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、盡可能采用疊印方式在底色上印文字和圖片，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.
