In the printing of color printed matter, there are many factors that will affect the quality of printed matter, resulting in a lot of printed matter not being well produced, of which overprinting is one of the main factors affecting the quality of printed matter. However, many factors will affect overprinting in the printing process. Therefore, pay attention to the following two points on the paper and printing plate during printing:

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(xiàn)象更容易出現(xiàn)。這是因?yàn)橛行┘垙埨w維的交織發(fā)生的間隙，均勻的涂層還沒(méi)有很好的覆蓋。這種壓紋紙和印版時(shí)，油墨層外表發(fā)生不良接觸。如果通過(guò)適當(dāng)?shù)挠∷毫?，可以有足夠的接觸時(shí)間與油墨層的布局的紙張的平滑性差，實(shí)現(xiàn)均勻的壓印接觸，可以確保印刷墨層均勻平服。

1、 The coarser the surface of the paper, the greater the amount of ink absorbed. The rough surface of the printing paper makes the ink overflow more likely. This is because the gap between the interlacing of some paper fibers and the uniform coating are not well covered. This kind of embossing paper and printing plate, the surface of the ink layer has bad contact. If an appropriate printing pressure is applied, the smoothness of the paper having sufficient contact time and the layout of the ink layer is poor, and uniform imprinting contact can be realized, and the printing ink layer can be ensured to be uniform and flat.

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(xiàn)油墨轉(zhuǎn)移不良現(xiàn)象，引起油墨布局不均的發(fā)生。這是因?yàn)槟静牡牡撞客斜P(pán)不夠強(qiáng)，變形的可能性也比較大，導(dǎo)致不穩(wěn)定的印刷壓力，油墨層的布局不能均勻地轉(zhuǎn)印到紙張上。好的方法就是做好備份操作技術(shù)，一些印刷板面積較大，應(yīng)選擇一些平整度好，比擬扎實(shí)的金屬版本的護(hù)理，可以更好的防止這些現(xiàn)象的發(fā)生。

2、 The printing plate of the bottom support in front of the conservative plywood has not only many disadvantages, but also is prone to poor ink transfer, resulting in uneven ink layout. This is because the bottom tray of the wood is not strong enough and the possibility of deformation is relatively large, resulting in unstable printing pressure and the layout of the ink layer cannot be uniformly transferred to the paper. A good method is to do a good job in backup operation technology. Some printed boards have a large area, so we should choose some metal versions with good flatness and solid care, which can better prevent these phenomena

彩色印刷品在設(shè)計(jì)和疊印的處理上要注意以下六點(diǎn)：

The following six points should be paid attention to in the design and overprinting of color printing:

1、字形過(guò)小的文字應(yīng)避免選擇筆畫(huà)太細(xì)的字體，比如仿宋體、細(xì)圓體等，字體的筆畫(huà)原本就細(xì)，如果字形過(guò)小，印刷時(shí)筆畫(huà)就容易丟失，導(dǎo)致字跡不全；

1. If the font is too small, the font with too fine strokes should be avoided, such as imitation song style and fine round style. The strokes of the font are originally thin. If the font is too small, the strokes are easy to be lost during printing, resulting in incomplete handwriting;

2、尤其是細(xì)小的文字，應(yīng)避免使用多色套??；

2. In particular, the use of multicolor overprint should be avoided for small words;

3、盡量避免使用細(xì)小的反白文字；

3. Try to avoid using small anti white words;

4、細(xì)小的文字應(yīng)避免疊印在深色的背景上；

4. Small words should not be overprinted on the dark background;

5、細(xì)小的文字應(yīng)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(xì)小的文字時(shí)，容易導(dǎo)致字跡模糊等問(wèn)題；

5. Small characters should be printed with gold ink and silver ink. The particles of gold ink and silver ink are thicker than those of ordinary ink. When used for printing small characters, it is easy to cause problems such as blurred handwriting;

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 overprinting method to print words and pictures on the background color, instead of hollowing out on the background color plate.

在彩色印刷品設(shè)計(jì)印制時(shí)注意這些問(wèn)題，可防止后面發(fā)生很多不必要的浪費(fèi)，還可呈現(xiàn)給客戶(hù)精美的印品，何樂(lè)而不為呢。

Pay attention to these problems in the design and printing of color printing materials, which can prevent a lot of unnecessary waste behind, and can also present the customers with beautiful printing materials. Why not.
