Carton packaging is an important factor to attract consumers' consumption, and the printing quality of carton can not be ignored. Vegetable packaging manufacturers for you to introduce the potato packaging carton printing common problems and solutions, please collect!

　　1、機(jī)械沖壓件質(zhì)量差造成的故障

　　1. Failure caused by poor quality of mechanical stamping parts

　　當(dāng)與沖壓有關(guān)的缸蓋、滾子頭、傳動(dòng)軸、齒輪等重要零件磨損或松動(dòng)時(shí)，壓板輥或壓板輥在沖壓過(guò)程中會(huì)跳動(dòng)或滑動(dòng)。由于壓力不穩(wěn)定，印版與紙板的接觸不正常，導(dǎo)致印版或部分圖文印在紙板的表面。通過(guò)仔細(xì)的觀察和分析，找出故障的準(zhǔn)確位置，采取相應(yīng)的處理措施，對(duì)磨損、松動(dòng)的部件進(jìn)行修理，排除故障。

　　When the cylinder head, roller head, transmission shaft, gear and other important parts related to stamping are worn or loose, the pressing roller or pressing roller will jump or slide during stamping. Due to the unstable pressure, the contact between the plate and the paperboard is abnormal, resulting in the plate or part of the image and text printed on the surface of the paperboard. Through careful observation and analysis, find out the exact location of the fault, take corresponding treatment measures, repair the worn and loose parts, and eliminate the fault.

　　2. 輥筒調(diào)整不當(dāng)造成質(zhì)量問(wèn)題

　　2. Improper adjustment of roller causes quality problems

　　如果壓輥的位置太高或太低,這樣壓輥和瓦楞紙板接觸太緊或太松,臟盤子,粘貼板或部分圖形打印跟蹤不清楚,應(yīng)調(diào)整到適當(dāng)?shù)奈恢玫膲狠?這之間的差距壓輥和壓輥適用于紙板的厚度,以保證印刷板的位置,不要讓失敗。

　　If the position of the press roll is too high or too low, so the contact between the press roll and the corrugated board is too tight or too loose, the dirty plate, the paste board or part of the graphic printing trace is not clear, the press roll should be adjusted to the appropriate position, and the gap between the press roll and the press roll is applicable to the thickness of the board, so as to ensure the position of the printed board and not to let it fail.

　　3.墨輥質(zhì)量差造成質(zhì)量問(wèn)題

　　3. Poor quality of ink roller causes quality problems

　　當(dāng)墨輥頭松動(dòng)時(shí)，墨輥本體發(fā)生彎曲、變形或表面損壞，也會(huì)造成版面臟污，粘貼版或局部文字不清。找出原因并采取相應(yīng)的處理措施，使油墨輥與印版保持均勻、適當(dāng)?shù)慕佑|狀態(tài)。只有更換損壞的輥筒，才能故障。

　　When the ink roller head is loose, the body of the ink roller is bent, deformed or the surface is damaged, which will also cause the layout to be dirty, and the pasted version or local text is unclear. Find out the reasons and take corresponding measures to keep the ink roller and the plate in uniform and proper contact. Only by replacing the damaged roller can the fault be eliminated.

　　4、瓦楞紙板厚度不均，土豆包裝紙箱質(zhì)量不合格

　　4. The thickness of corrugated board is uneven, and the quality of potato packaging carton is unqualified

　　如果瓦楞紙板的外形表面為損壞的凹痕，紙張表面的凹痕也會(huì)有模糊的質(zhì)量缺陷。如果用印刷壓力的提高來(lái)彌補(bǔ)這一不足，則很容易在文本和行布局中造成粘貼質(zhì)量問(wèn)題。為了不讓紙板糊，瓦楞紙板在堆放和搬運(yùn)過(guò)程中應(yīng)輕放(控制堆放高)，不要用拋、砸、壓等不良的生產(chǎn)習(xí)慣。

　　If the corrugated board surface is damaged dent, the paper surface dent will also have fuzzy quality defects. If we use the increase of printing pressure to make up for this deficiency, it is easy to cause paste quality problems in text and line layout. In order to prevent the board from being pasted, the corrugated board should be placed with care (to control the stacking height) in the process of stacking and handling, and the bad production habits such as throwing, smashing and pressing should not be used.

　　5. 板厚不均勻引起的質(zhì)量破壞

　　5. Quality damage caused by uneven plate thickness

　　當(dāng)橡膠板的厚度不均勻時(shí)，就會(huì)產(chǎn)生板高差。為了不讓這種情況發(fā)生，我們可以采取散亂制版的辦法，把制版分成若干小塊。我們應(yīng)該用同一個(gè)板分開(kāi)做，這樣厚度差就會(huì)小一些。如果已經(jīng)做了膠印，而且有厚薄差別，可以在一些紙的背面加一層橡皮，使整個(gè)印版的厚薄保持基本相同，以保證印版的印刷壓力和油墨的均勻性。

　　When the thickness of the rubber plate is not uniform, there will be a height difference. In order not to let this happen, we can take the method of scattered plate making and divide the plate making into several small pieces. We should do it separately with the same plate, so that the thickness difference will be smaller. If offset printing has been done, and there is a thickness difference, you can add a layer of rubber on the back of some paper to keep the thickness of the whole plate basically the same, so as to ensure the printing pressure and ink uniformity of the plate.

　　6、因土豆紙箱包裝顏色順序不當(dāng)造成紙箱質(zhì)量問(wèn)題

　　6. Quality problems of potato cartons caused by improper color sequence

　　瓦楞紙板進(jìn)入印刷過(guò)程后的下一色彩組機(jī)理，由于油墨量大，干燥速度慢，容易轉(zhuǎn)移印痕，造成紙張臟。為了防止這一缺陷，建議在彩色印刷中安排小面積，在后續(xù)的彩色印刷中安排大面積，以免因臟印而造成的痕跡轉(zhuǎn)移。

　　After the corrugated board enters the printing process, the next color group mechanism, due to the large amount of ink, slow drying speed, easy to transfer the marks, causing paper dirty. In order to prevent this defect, it is suggested to arrange a small area in the color printing and a large area in the subsequent color printing to avoid the trace transfer caused by dirty printing.
