What is the main process of screen printing? Is the process flow needle?
The main process of screen printing is: making originals, making screen printing plates, printing, ink drying, etc.
What is a Tensiometer?
Tensiometer is an instrument that measures the mutual traction force between the inside of the wire mesh and the fixed wire mesh contact body when the wire mesh is subjected to tension. There are two types of tensiometers, mechanical and electronic, and 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 kind of relative value to express the tension. It is calculated by the value (mm) of the sinking depth of the screen by the weight of the tension meter.
The tension value can be obtained directly from the indicator panel, or indirectly from the control panel. get. There are two types of tension meter: manual operation and mechanical operation. Tensiometer is an important testing instrument for testing the quality of screen printing plates. In order to ensure the tension required for plate making, use a tensiometer to measure during or after stretching the net.
What is a mesh ruler? What is its purpose?
The mesh ruler is also called the latitude and longitude density meter. Mainly used to measure the mesh size of various wire meshes. There are two types of mesh rulers: glass plate type and plastic plate type. The measurement method is: when measuring, first make the wire mesh in a transparent state or put it on the viewing table, put the mesh ruler on the wire mesh, and then move the mesh ruler slowly on the wire mesh to make the mesh. The vertical line on the ruler is parallel to the warp or weft of the wire mesh. At this time, due to the overlapping effect of the warp and weft of the wire mesh and the vertical line on the mesh ruler, a prismatic pattern is formed on the mesh ruler. The corresponding scale number on the mesh ruler is the mesh number (inch or centimeter) of the screen to be measured.
The mesh ruler is a common tool for measuring the number of wire meshes. Usually, to maintain the accuracy of the measuring instrument and the accuracy of the measurement data, it is necessary to keep the mesh ruler clean to prevent scratches and bumps on the mesh ruler. Wipe the instrument clean and keep it properly.
What is a density meter? What is a density meter used for?
Densitometers are commonly used manuscript measuring instruments in printing plants. It is a photoelectric measuring instrument for measuring the gray value of black and white originals and measuring the continuous tone or dot value. There are two types of densitometers: transmission densitometers and reflection densitometers. Transmission densitometers are suitable for measuring transparent originals, and reflection densitometers are suitable for measuring solid originals. The measuring range of the densitometer is 0-2.5, the higher the number, the higher the blackness. The basic principle of measurement is to measure the degree of blackening of the photosensitive material after exposure and development, that is, blackness. During plate making, the silver bromide on the photosensitive material is exposed to light, and after development, it is reduced to metallic silver, forming a certain degree of light resistance. The blackness is large, the density is high; the blackness is small, the density is low. A meter with an optical filter that can also measure the color density of color originals. Its measurement principle is similar to the above-mentioned basic principle.
What is a colorimeter? What is it used for?
Colorimeter is also called colorimeter. It is an instrument for measuring the color characteristics of materials. The main purpose of the colorimeter is to measure and analyze the color, hue and color value of the tested material. If the colorimeter is connected to the computer, the ability to analyze and process colors can be improved, and users can search and call out various data from the color storage library of the microcomputer for color matching according to their needs.
What is a durometer? What is it used for?
The hardness tester is an instrument for measuring the hardness of an object. According to the degree of complexity, it can be divided into two types: simple hardness tester and complex hardness tester. The hardness tester is widely used and is commonly used in the rubber industry. In the screen printing process, the hardness tester is mainly used to detect the hardness of the scraper material.
