screen printing squeegee durometer refers to what?

screen printing squeegee durometer  refers to the surface hardness. Often in Shore durometer, the hardness range of 55 durometer Celsius to 95 durometer Celsius, there are: 55 durometer squeegee, 60 durometer squeegee, 65 durometer squeegee, 70 durometer squeegee, 75 durometer squeegee, 80 durometer squeegee, 85 durometer squeegee. Cross-sectional shape generally have right angle, sharp angle and arc type and so on. Detailed specifications are: 50 * 9mm, 50 * 5mm, 45 * 5mm, 40 * 5mm, 35 * 5mm, 25 * 5mm and so on. This range of screen printing is also used as a measure of durometer. Scratch durometer from the highest to the lowest five Shore hardness for the same diminishing, to ensure the stability of the printing quality. The hardness of the squeegee The degree of squeegee deformation and bending, squeegee and the squeegee coefficient will vary with the manufacturer of squeegee, which can be printed only when manifested. The hardness of the squeegee affects how the squeegee lines up with the substrate and determines how much pressure should be exerted on the squeegee to allow the ink to flow through the screen version. Squeegee softer, squeegee and screen surface, the better the fit, the smaller the printing pressure required, the opposite.

Distinguish between the Shore durometer, and plastic scratch hardness

1,55  durometer to 65 durometer for soft plastic squeegee.

2,65 durometer to 75 durometer, for the hard rubber scratch.

3,75 durometers to 95 durometer, for hard plastic scratch.
