Screen printing blade hardness tester refers to surface hardness. Usually in the Shore hardness tester, the hardness range is 55 hardness Celsius to 95 degrees Celsius, there are: 55 hardness scraper, 60 hardness scraper, 65 hardness scraper, 70 hardness scraper, 75 hardness scraper, 80 hardness scraper, 85 hardness 
scraper. The cross-sectional shape generally has a right angle, an acute angle, an arc shape, and the like. Detailed specifications are: 50 * 9mm, 50 * 5mm, 45 * 5mm, 40 * 5mm, 35 * 5mm, 25 * 5mm and so on. This screen printing range is also used as a measure of the durometer. The five Shore hardnesses from the highest to the lowest of the scratch hardness are also reduced to ensure the stability of the print quality. The hardness of the blade is deformed and the degree of bending. The blade and blade coefficients will vary with the manufacturer of the blade. The manufacturer of the blade can only print when it is displayed. The hardness of the squeegee affects how the screed is aligned with the substrate and determines how much pressure should be applied to the squeegee to allow the ink to flow through the screen version. The blade is softer, the blade and the screen surface, the better the fit, the smaller the printing pressure required, and vice versa.

Distinguish between Shore hardness tester and plastic scratch hardness
A plastic scraper with a hardness of 1,55 to 65 hardness.
Hardness is 265 durometer to 75 hardness for hard rubber scratches.
3,75 durometer to 95 durometer for hard plastic scratches.
