In the production of multi-color screens, the process of pulling the net yarn on the screen frame is the same as that of the monochrome screen. It is possible to use a screen-drawing machine or a manual stretch screen. However, pay attention to multi-screen screens. The size of the selected screen frame is the same. If the size is different, it will seriously affect the positioning of multi-color screen printing.

After the design is printed, you need to select the corresponding screen frame and stretch the net yarn. The size of the screen frame is 5 cm longer than the sides of the pattern. For example, if the size of the pattern is a rectangle of 5 * 10 cm, the inner diameter of the corresponding screen frame is selected. For the size of 10 * 20 cm, if the inner diameter of the selected screen frame is the same as the pattern, it will be difficult to print the edge area when the screen is printed.

Net frame stretch net can be divided into manual net and machine net.

If the production volume is small, it is only occasionally to make a screen. In this case, you can choose to manually stretch the screen, but there are many restrictions on manual stretch, especially for novices, it is difficult to grasp the strength of the net yarn, and the uneven strength of the net yarn is very It is difficult to stretch flatly. Therefore, it is necessary to manually stretch the net and stretch the net to make a qualified screen version.

Machine stretch screens generally have a certain scale and a large number of screens are produced. This kind of screen can be used to pull the screen, and multiple screens can be placed at one time. Multiple blank screens can be made at the same time, which can save high efficiency and save A lot of time.

What kind of mesh should be selected when stretching the net?

If water-based glue is used for screen printing, then 80-120 mesh gauze can be selected. This specification can be used for most glues. If printing with ink, generally use 200-300 mesh gauze. The printed pattern is that good. In this case, a mesh of 300 mesh or more is generally used.
