有客戶提到一個(gè)問(wèn)題，彩盒制作過(guò)程中為什么要除粉？

這個(gè)粉是從那里來(lái)的？在紙張的印刷過(guò)程中，為了盡快使油墨干燥，會(huì)采用噴粉技術(shù)加快油墨的干燥，一般只有印刷制品的一面需要噴粉干燥，另一面并不需要噴粉，但是在噴粉過(guò)程中，粉塵并不容易受到控制，因此往往不需要噴粉的印刷制品另一面也會(huì)粘有不少的粉塵，而這些粉塵對(duì)于印刷制品的覆膜影響比較大，易引起覆膜牢度的降低，起膜等問(wèn)題。

接下來(lái)就跟大家講一下彩盒為什么除粉。

在印刷好的紙張覆膜前就要進(jìn)行除粉作業(yè)，一般都會(huì)加裝若干根毛刷輥，用于清除印刷制品表面的粉塵，為了提高粉塵的清除率還會(huì)加裝一個(gè)負(fù)壓吸風(fēng)裝置，將清掃下來(lái)的粉塵直接吸走，避免粉塵在印刷制品上的二次附著。如果是自動(dòng)覆膜機(jī)的話，在機(jī)器前端都安裝有高效除粉設(shè)備，在紙張未過(guò)膠之前通過(guò)除粉裝置往往能達(dá)到去除粉末的作用。

彩盒制作過(guò)程中除粉是為了覆膜，防止粉塵在印刷彩盒表面附著，這樣做出來(lái)的彩盒才會(huì)更加漂亮。

A customer mentioned a problem, why to powder in the process of making color box? Where did this powder come from? In the printing process of paper, in order to make the ink dry as soon as possible, the ink will be accelerated by dusting technology. Generally, only one side of the printed product needs to be dusted to dry, and the other side does not need to be dusted. However, during the dusting process, dust is not easy to control, so often do not need to spray powder on the other side of the printed products will also stick to a lot of dust, and these dust for the coated products of the larger impact, easy to cause the coating fastness of the reduced, the problem such as the membrane. Let's talk about why the color box is not pink. Before covering the printed paper with plastic film, a number of brush rollers are usually installed to remove the dust on the surface of the printed product. In order to improve the dust removal rate, a negative pressure suction device is also installed The cleaned dust is directly sucked away to avoid the second adhesion of the dust on the printed products. If it is an automatic laminating machine, in the front of the machine are installed with efficient powder removal equipment, in the paper before glue through the device can often achieve the role of powder removal. Color box production process in addition to powder is to cover, to prevent dust in the printing color box surface attached, so that the color box will be more beautiful.
