Today I will give you a detailed introduction to the decontamination method of the Stenter screen.

When we use the screen printing machine for screen printing production, we can't avoid the decontamination of the screen of the screen printing screen. However, we often use the screen printing machine to screen different types of products, which often causes the dirt on the screen to be cleaned. This reduces waste, affects printing quality, and shortens the service life of the template.

When there is dirt or dry ink on the printing part of the picture, the screen should be decontaminated, and the screen frame should be lifted after stopping the printing machine. At this time, some operators will wipe vigorously with an emery cloth dipped in solvent On the lower side of the template, the loud voice can be heard throughout the printing workshop, and the template is often damaged.

A truly knowledgeable operator seldom rubs the graphic printing surface of the template form hard, because he knows that the clarity of the printed graphic requires that all graphic edges maintain a clear emulsion layer graphic interface. Vigorous rubbing will damage the graphic interface of the emulsion layer, or even wipe off the emulsion layer, leaving only bald meshes.

When printing color images with high screen count, the emulsifier film under the silk threads is only 5-6um thick, and the silk thread diameter of the mesh itself may be only 30um, which cannot withstand strong friction. Therefore, the key to avoiding rough decontamination is to prevent the template from being contaminated first.

The main cause of stencil contamination is improper ink control, resulting in dry ink remaining in the mesh. When using solvent-based inks or water-based inks, the reason is that the ink is too thin or too thick. There should be no change in the state of ink adjustment. When using UV-curable inks, you should try to avoid the screen from being irradiated by UV lamps and also avoid sunlight.

The above is the decontamination method of Flat Screen Printing Machine screen introduced by the editor, I hope it can be helpful to everyone.
