Some useful tools for printing mesh will be introduced in this article.
What is a tension meter?
The tension meter is an instrument that measures the mutual traction force between the printing mesh contact body when the wire mesh is subjected to a pulling force. Tension meters are available in both mechanical and electronic versions. The unit for measuring tension is expressed in Newtons/cm. Tension can also be expressed as a relative value. The centimeter tension meter is a type that expresses the tension with a relative value. It is calculated by the value of the depth (mm) of the screen sinking by the weight of the tension meter itself. The tension value can be obtained directly from the indicator disc or indirectly from the control panel. get. Tension meter has two kinds of manual operation and mechanical operation. Tension meter is an important instrument for checking the quality of screen printing plates. In order to ensure the tension required for plate making, a tensiometer measurement is used during or after stretching.
What is a mesh ruler? What is its function?
Mesh and Weft Density Meters It is mainly used to measure the mesh number of various printing mesh. There are two types of glass ruler: glass plate and plastic plate. The measurement method is: When measuring, first make the screen in a transparent state or on the table, put the mesh ruler on the screen, and then slowly move the mesh ruler on the screen to make the mesh. The vertical line on the target ruler is parallel to the meridian or weft of the wire mesh. At this time, due to the overlapping effect of the wire mesh latitude and longitude lines and the vertical line on the mesh ruler, a diamond pattern is formed on the mesh ruler, and the transverse diagonal of the pattern indicates The corresponding scale number on the screen ruler is the number of screens (inches or centimeters) measured.
Mesh ruler is a common tool for measuring the number of meshes for printing mesh. It is usually necessary to maintain the accuracy of the measuring instrument and the accuracy of the measurement data. It is necessary to keep the mesh ruler clean and prevent scratches and bumps on the mesh ruler. Wipe the instrument clean and keep it properly.
