包裝盒印刷中常常會出現(xiàn)重形，字跡模糊，字體歪曲及套印不準(zhǔn)的現(xiàn)象出現(xiàn)，今天山東印刷包裝廠家將逐個研究問題出現(xiàn)的原因及辦法，如下：

In the printing of packaging boxes, there are often many phenomena, such as duplicate shapes, blurred handwriting, distorted fonts and inaccurate overprinting. Today, Shandong printing and packaging manufacturers will study the causes and solutions of the problems one by one, as follows:

包裝盒印刷過程中如果調(diào)整不當(dāng)，往往會生成印刷字體有重形出現(xiàn)，造成這種現(xiàn)象主要是設(shè)備振動過大或機速不穩(wěn)所致；另外一個成因與墨輥的壓力也有很大關(guān)系，這個現(xiàn)象我們常用方法就是在生產(chǎn)前把墨輥壓力調(diào)好的狀態(tài)，開機生產(chǎn)進(jìn)行中勻速開機，且設(shè)備應(yīng)無“帶病”開機，對于字體歪曲套印不準(zhǔn)則完全取決于操作人員對設(shè)備的調(diào)整是否完全達(dá)到好的狀態(tài)，且與操作人員的熟練程度有關(guān)；

If the packaging box is improperly adjusted in the printing process, it will often produce the printing font with double shape, which is mainly caused by excessive vibration of the equipment or unstable machine speed; Another cause is also closely related to the pressure of the ink roller. Our common method to solve this problem is to adjust the pressure of the ink roller to a good state before production, start the machine at a constant speed during production, and the machine should be started without "defects". The inaccurate overprinting of font distortion depends entirely on whether the operator adjusts the machine to a good state, and is related to the proficiency of the operator;

現(xiàn)今由于產(chǎn)品包裝各包裝印刷廠都有嚴(yán)格的要求，像包裝盒類對于盒子承壓都有很高要求，這就要求印刷生產(chǎn)過程中會嚴(yán)格控制送紙輥的間隙壓力，避免壓力過大導(dǎo)致紙板厚度受損，瓦楞也會因受壓造成愣形受損，這樣就會直接導(dǎo)致成型后的紙箱承壓降低；另一個原因影響紙板厚度成因與版面所用的材版也有很大關(guān)系。

Nowadays, due to the strict requirements of all packaging and printing plants for product packaging, such as packaging boxes, there are high requirements for box pressure, which requires that the gap pressure of the paper feeding roller should be strictly controlled during the printing production process to avoid the damage of cardboard thickness caused by excessive pressure, and the corrugation will also be damaged due to pressure, which will directly lead to the reduction of the pressure of the formed carton; Another reason that affects the thickness of paperboard has a lot to do with the plate used in the layout.

本來紙板厚度瓦楞成型能達(dá)到7.0mm~7.5mm，但經(jīng)過印刷這個工序后只有7mm，有時甚達(dá)不到7mm，這是因為如果版面采用橡膠版且版面如果設(shè)計圖案文字過大，在生產(chǎn)中為了保證印刷版面效果，就會顧及不到紙板厚度，甚壓力過大會直接導(dǎo)致瓦楞壓潰破損。據(jù)此，建議在大面積要求高的產(chǎn)品，盡可能采用柔性版印刷，減少因版面壓力造成的紙板不合格現(xiàn)象；

Originally, the thickness of the corrugated board can reach 7.0mm~7.5mm, but after the printing process, it is only 7mm, sometimes even less than 7mm. This is because if the rubber plate is used for the layout and the design of the layout is too large, in order to ensure the effect of the printing layout in production, the thickness of the board will not be taken into account, and even the pressure will directly lead to the collapse of the corrugated board. Therefore, it is suggested that flexographic printing should be used as much as possible for products with high requirements in large areas to reduce the unqualified phenomenon of paperboard caused by the pressure of the layout;

很多時候碰到印跡模糊的現(xiàn)象人們都會采用清洗膠版來，其實，這樣做都忽略了壓力的問題以及重復(fù)調(diào)試版面而造成版面積墨的問題，對此建議生產(chǎn)前，調(diào)試完畢后再清洗膠版，且根據(jù)膠版的質(zhì)量將壓力調(diào)好的狀態(tài)，像印跡模糊，重形現(xiàn)象基本可以不出現(xiàn)，對于透楞現(xiàn)象，出現(xiàn)這種情況不排除紙板用材問題；另一方面在于用墨的濃度以及下輥壓力也有很大關(guān)系，如用墨濃度不可太稀，那樣會增加版面的覆蓋率，降低透楞現(xiàn)象發(fā)生。

In many cases, people will use cleaning the offset plate to solve the problem of blurred prints. In fact, this ignores the problem of pressure and the problem of ink area caused by repeated debugging of the plate. It is suggested that the offset plate should be cleaned before production and after debugging, and the pressure should be adjusted to a good state according to the quality of the offset plate. The phenomena such as blurred prints and reshaping can basically be avoided. For the phenomenon of corrugation, This situation does not rule out the problem of cardboard materials; On the other hand, the concentration of the ink and the pressure of the lower roller also have a great relationship. If the concentration of the ink is not too thin, it will increase the coverage of the page and reduce the occurrence of the corrugation phenomenon.

在包裝盒印刷中有一個不可忽視的問題，那就是開槽帶掛，切角不干凈的現(xiàn)象，還有就是把手有裂開現(xiàn)象的發(fā)生，像我們常見的開槽不干凈，有掛邊是紙箱印刷中經(jīng)常出現(xiàn)的現(xiàn)象，這與紙板材質(zhì)有關(guān)；另一方面與設(shè)備的磨損也有關(guān)，像這個問題可采用提高切槽深度，減少上刀與下刀的間隙，切不可能盲目換刀，再一個對于把手有裂開，一般內(nèi)切式不會出現(xiàn)面紙裂開，但對于外切把手，因面紙直接受力，所以我們在印刷中一定做到預(yù)壓，緩沖一下，面紙直接受力（在不影響質(zhì)量和強度的情況下）。有問題隨時來我們網(wǎng)站http://buiy.cn咨詢！

There is a problem that cannot be ignored in the printing of packaging boxes, that is, the phenomenon of grooving and hanging, and the uncleanness of cutting corners, as well as the occurrence of cracking of the handle, such as our common phenomenon of uncleanness of grooving and hanging edges, which is a common phenomenon in carton printing, which is related to the material of cardboard; On the other hand, it is also related to the wear of the equipment. For example, to solve this problem, we can improve the cutting depth, reduce the gap between the upper knife and the lower knife. It is impossible to change the knife blindly. On the other hand, the handle is cracked. Generally, the face paper will not crack in the internal cutting type, but for the external cutting handle, because the face paper is directly stressed, we must pre-press and buffer it in printing, The face paper is directly stressed (without affecting the quality and strength).
