The screen printing method of the stretcher is relatively loose, and the wire mesh is only used in one case, that is, for a circular or irregular pattern of the substrate, which is to make the wire The mesh is in full contact with the various parts of the substrate. After another day or two of measurement, the length has increased.
An important issue to be aware of when analyzing the stretch nets at Anmei Mall is to tighten it.
The tools used in the stretcher also limit or increase the tension of the stretcher. Therefore, the mesh number is only an inaccurate parameter of the mesh support tension, and the wire diameter is the most important core. In the past, manual stretchers were sure to reach the required tension. There may be countless ways for a tote bag to show you how good a method is, but you have to give scientific evidence to prove why this method is the best. For example, the tension supported by a wire-inch screen may be greater than the tension supported by a wire-inch or wire-inch wire mesh. The answer is yes.
In the screen printing factory, it is the largest printing enterprise with the most production potential in China. In industry, you may find countless theories and techniques, even if it's a seemingly simple place to open the ink tank lid or tighten the wire mesh.
Experienced teachers often use rubber bands as a metaphor when they talk about this problem. However, in the flat screen printing factory, it is the largest printing enterprise with the most production potential in China. In the middle, the high-pull tote bag can not only improve the production quality, but also achieve higher production speed. After two printings, the original Newton fell to Newton. Subsequent cleaning, degreasing, and coating will reduce Newton's.
Screens with a mesh number of microns in diameter and a micron diameter are different on the x inch frame from the tension supported on the x inch frame.
It is a key point of the stretch net to ensure that the tension of all parts of the screen is consistent. Until it reaches a stable length, it no longer increases with time. In fact, the reason why the tension may cause damage to the screen is because the printing process is not well mastered. If you can keep the lower hole in the hole, reduce the pressure of the squeegee, and control the printing table, It is gratifying to see the quality of printing brought about by high tension.
If you have all of the above conditions, you should be able to make a better screen version. However, if the quality of the production staff is low and the work is not serious, a good screen version cannot be produced. Recycling, tension will reduce Newton. The re-tensionable mesh frame is designed for this purpose, and it can be tensioned after each use until it is stable. We experimented with a wire mesh with a mesh number of inches. The pneumatic tensioning system can reach Newton on a x inch frame and Newton on a x inch frame. There is an article saying that if the tension is too large, it will cause damage to the screen. Only in this way will the product quality be gradually improved and the work efficiency will gradually increase. The result of this may be dot gain and color drift. Success comes from the continuous improvement of the capacity of the screen printing factory, rather than the ability to reverse or stop, to take the initiative to strive for excellence. The number of meshes is an obvious factor, but here some textile green handbag printing refers to the specific number of lines per inch, but refers to the diameter of the line decreases as the number of lines increases.
Screen size (or frame size) is another factor. The reason why the screen tension changes is the same, so it is best to use a new stretch screen version for color overprinting, or a tight screen version to be used after stabilization. However, how much tension can be achieved on a large-format frame? There is an article that the mesh with a mesh number of inches can obtain no more tension than Newton on a x-inch frame.
In the stretch net method, the biggest problem is how to deal with the slack of the wire mesh after punishing the stretch net. After the machine is printed, the tension will fade, and two or three Newtons or more will disappear. Note that this small place means "re-tensioning" does not mean that the frame itself will be self-tensioning, and there is no kind of frame that has self-tensioning function. Therefore, it is necessary to strengthen the training of the production staff and the ability of the production staff. It is related to the type of training they receive, to the trainer, and to the standard of training.
Why is it necessary to use the entire screen-drawing factory as a factory for the production of professional printed non-woven bags. The quality of non-woven bag printing is first class in China. The quality of non-woven bag printing is first class in China. Printing quality is first class in China. The force is consistent. This is because the squeegee and the floating rod are not very flexible. If the tension at the center point and the right side of the screen is Newton and the tension on the left is Newton, then the pressure of the squeegee must be adjusted to ensure The amount of ink supplied is the same. After a stretch, the screen version that reaches Newton's tension will be less than Newton after overnight and may fade to Newton. Cut a rubber band, nail one end to the wall, hang the object on the other end and put it into the water. Measure the length of the rubber band of the original non-woven fabric factory. After measuring the length again one day, you will find that the length has increased.
The factors affecting the tension of the screen mainly include the mesh size of the mesh, the stretching method, the stretching equipment and the stretch screen printing factory. It is the largest printing enterprise with the most production potential in China. The experience of the network personnel. Based on this, here is a personal opinion about the stretch net. However, it is also the line inch. Is the tension supported by the wire mesh of micrometer diameter larger than the tension supported by the wire mesh of the diameter of micrometer? Actually it is not, it is worse than Newton.
In fact, unless you use a screen printing machine, there is no way to make it completely stable.
As a printing technician, you must do your best.
The smaller the frame size, the greater the tension that can be achieved. If you want to produce a screen version of more than one inch, it is recommended to check the tension of the screen position, that is, the center of the screen plate, the four corners, and the midpoint of each side. Regardless of the tension at the center point, the tension difference between the other points and the center point should be within ±1.
