Screen printing technology

The quality of screen printing is also very relevant to the relationship between screen printing. A very good quality precision screen. The printed graphic effect is very good. We think about the poor quality of the screen. Where do you want high-quality printing products? Below we have a professional understanding of the technology of the screen printing mesh.

1. High standard and rigorous stretching method.

The screen can be stretched to the desired tension value in 1-3 minutes, but it needs to be stretched for more than 15 minutes before the screen is fixed to the aluminum alloy frame. Therefore, repeating this process several times will reduce future tension losses. After the maximum tension is reached, the mesh is finally fixed in the adhesive mesh. The tension of the screen is an important factor in ensuring accurate overprinting and determining the proper web spacing. In general, the higher the mesh size, the finer the mesh, and the thicker mesh is pulled tighter than the fine mesh. Generally, the overprinted screen version requires 24 hours to re-print the net after the net is pulled, so that the net cloth rebounds to a stable value, otherwise there will be inaccurate overprinting or graphic deformation. The choice of mesh: For the material of the mesh, we generally choose nylon mesh and polyester mesh.

2, pay attention to the choice of aluminum alloy frame.

The frame of the aluminum alloy can be divided into a main profile such as a wide heart type, a Japanese type, and a field type. We can choose according to our own needs.

3, the selection of photosensitive adhesive attention.

You can choose a better brand manufacturer, such as Murakami, Tian Ling, Ke Tutai, for the thickness of the screen film, we can choose to use the film to make the screen.

4. Detailed plate making process.

Make a good impression of the thickness of the screen on the top of the screen. Then dry. Then use the plate-making film to fit it into the plate printer. After development, rinsing, and drying, it becomes a screen printing screen.

Process popular: photosensitive paste preparation has been stretched - degreasing - drying - coating film - drying - exposure - development - drying - revision - final exposure - sealing network
