Screen printing meshs use a lot of industries, what is its tension? After learning the data, the measuring unit of tension is Newton/cm. During the stretch of the net, the measuring staff will use the measuring instrument to measure the tension. In summary, the higher the reading on the tension measuring instrument, the better the printing result of the mesh arrival.
The tension that a Screen printing mesh can absorb is certain. If the tension is exceeded, the screen will break or fall off the frame.
Due to the tension, the frame is prone to camber, and the thickness of this camber changes with the size of the frame. As usual, the smaller the frame, the more tension it can with (30 N/cm or more). However, once the actual size of the frame reaches 3 square feet (even if it is a little), the tension needs to be within the range of 15-25 Newtons/cm. In addition, for those frames that are oversized, it is necessary to have a bracket or other support layout to prevent them from bending.
Due to planning reasons, some high-tension, low-extension Screen printing mesh are not affected by the first target mentioned above, and allow the use of stencils with higher tension levels. Of course, users should follow the manufacturer's requirements for wire mesh tension grades.
The proper frame size is defined by the printed image. The rollers should be at least 4 inches apart from the inside of the image frame (measured on the degree of the image) to satisfy the running and outage requirements of the press. In addition, the roller should be more than 3 inches from the inside of the frame. In the usual environment, images of 11" x 15" are required to use a frame measuring 17" x 23" (at least) to eliminate printing problems. The larger the space around the print, the easier it is to reach the high scale. If the interval between the image and the screen is too cramped, it is easy to produce corresponding printing problems in the printing process, including printing stains, missing edges and distortions.
We should know something about the tension of screen printing meshs. The size of the tension is also crucial.
