引發印刷露白現象發生的原因多種多樣,如紙張吸水性,油墨粘度,印刷壓力、紙板上有紙屑、灰塵等等。當然,引發印刷露白的原因不同,那么解決問題的方式自然也不盡相同!今天濟南彩色乐天堂fun88体育的小編就給大家詳細的講解一下造成彩色乐天堂fun88体育露白的原因!

There are many reasons for the phenomenon of printing bleaching, such as the water absorption of paper, ink viscosity, printing pressure, paper scraps, dust on the cardboard and so on. Of course, the causes of printing exposure are different, so the way to solve the problem is naturally different! Today, the small edition of Jinan color design and printing will give you a detailed explanation of the causes of color design and printing white!

做為印刷人員,如何快速找到印刷露白的解決方向呢?往往造成印刷露白的原因不同,出現的露白也有細微的不同,印刷人員需要學會根據表象去判斷造成印刷露白的癥結所在,從而快速處理!我們大致可以從下面三個方面來看看。

As a printer, how to quickly find the solution direction of printing exposure? Often causes of printing exposure are different, and there are subtle differences in the appearance of exposure. Printers need to learn to judge the crux of printing exposure according to the image, so as to deal with it quickly! We can roughly look at the following three aspects.

1、先檢測未印刷的紙板厚度值,再檢查紙板從送紙單元出來后的紙板厚度值,看紙板是否有被送紙輪壓潰。如果壓潰了先解決紙板壓潰的問題,送紙間隙是紙板厚度-0.3mm。

  1. First check the thickness of unprinted cardboard, and then check the thickness of cardboard after it comes out of the feeding unit to see if the cardboard is crushed by the feeding wheel. If crushing first solves the crushing problem of cardboard, the paper feeding gap is cardboard thickness - 0.3mm.

2、以上都無誤再增加印刷壓力值,壓力值不應過大,過大容易產生印刷煳,印刷慢磨損加快。

2. Above all, the printing pressure value should not be too high. It is easy to produce printing press when the pressure value is too large, and the slow wear and tear of printing will be accelerated.

3、檢查印刷版壓是否正常,可以查看印刷版面是否有足夠的油墨量。印刷版硬度實地版適合在34-36度。

3. Check whether the printing press is normal, you can check whether the printing plate has enough ink. The hardness of the printing plate is suitable for the field version at 34-36 degrees.

如果印刷油墨粘度正確,印刷版、網紋輥良好還是出現印刷露白現象,主要調整方向以油墨工藝為主導,印刷壓力切勿一直加大,可以繼續提高油墨粘度,及油墨的滲透性,也可以將印刷機調整為隔張送紙狀態進行印刷。

If the viscosity of printing ink is correct, printing plate and screen roller are good or there is a phenomenon of printing bleaching. The main direction of adjustment is ink technology. Printing pressure should not always increase. It can continue to improve the ink viscosity and ink permeability. It can also adjust the printing press to separate sheet feeding for printing.
