在彩色印刷品印制時(shí)，有很多因素都會(huì)影響印刷品的質(zhì)量，導(dǎo)致很多印刷品制作出來不被看好，其中套印是影響印刷品質(zhì)量的主要因素之一。然而，印刷過程中很多因素均會(huì)影響套印。所以，印刷過程中要注意紙張與印版上出現(xiàn)的這兩大點(diǎn)：
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(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 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(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。比較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 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(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 overprint of color printed matter
1、字形過小的文字應(yīng)避免選擇筆畫太細(xì)的字體，比如仿宋體、細(xì)圓體等，字體的筆畫原本就細(xì)，如果字形過小，印刷時(shí)筆畫就容易丟失，導(dǎo)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(xì)小的文字，應(yīng)避免使用多色套??；
2. Especially for small words, multi-color overprint should be avoided;
3、盡量避免使用細(xì)小的反白文字；
3. Try to avoid using small negative words;
4、細(xì)小的文字應(yīng)避免疊印在深色的背景上；
4. Small text should avoid overprint on 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.
Pay attention to these problems in the design and printing of color prints, which can prevent a lot of unnecessary waste and present exquisite prints to customers. Why not.
