  • 彩盒制作过程要除粉的原因

有客户提到一个问题,彩盒制作过程中为什么要除粉?

这个粉是从那里来的?在纸张的印刷过程中,为了尽快使油墨干燥,会采用喷粉技术加快油墨的干燥,一般只有印刷制品的一面需要喷粉干燥,另一面并不需要喷粉,但是在喷粉过程中,粉尘并不容易受到控制,因此往往不需要喷粉的印刷制品另一面也会粘有不少的粉尘,而这些粉尘对于印刷制品的覆膜影响比较大,易引起覆膜牢度的降低,起膜等问题。

接下来就跟大家讲一下彩盒为什么除粉。

在印刷好的纸张覆膜前就要进行除粉作业,一般都会加装若干根毛刷辊,用于清除印刷制品表面的粉尘,为了提高粉尘的清除率还会加装一个负压吸风装置,将清扫下来的粉尘直接吸走,避免粉尘在印刷制品上的二次附着。如果是自动覆膜机的话,在机器前端都安装有高效除粉设备,在纸张未过胶之前通过除粉装置往往能达到去除粉末的作用。

彩盒制作过程中除粉是为了覆膜,防止粉尘在印刷彩盒表面附着,这样做出来的彩盒才会更加漂亮。

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.
