Representation and actual measurement of thickness, the value of thickness is called "nominal thickness". This method of representation is in accordance with the requirements of ISO specifications. The actual thickness is provided by the blanket manufacturer according to the printing press and practical conditions, so this thickness is not limited to be the same as the measured thickness. To this end, the blanket manufacturer will attach a checklist with the measured thickness to each roll of blanket, or print the value on the back of the blanket. Hardness generally refers to the surface hardness of the blanket, that is, the overall hardness value of the rubber surface layer, the base cloth layer and the compression layer, which is expressed by the Shore hardness value as an indicator of the compression performance of the blanket. Reverse elasticity is expressed in%, and a certain weight cone is dropped onto the rubber surface of the blanket to determine its rebound force. This value can be regarded as the energy absorption of the blanket. This is closely related to the quality of the surface rubber? The quality of the air cushion layer has a great influence on the quality of the air cushion blanket and printed products. The elongation is expressed in%, a certain load is reinforced in the longitudinal direction of the test product of the specified size, and the elongation obtained by the calculation formula after a certain time is determined. This value has a close relationship with the base fabric structure of the blanket, and has an effect on the amount of tightening of the blanket during the printing process and the thickness of the rubber nose. The breaking strength is expressed in%, a certain load is reinforced in the longitudinal direction of the test article of the specified size, and it is carried out at a certain stretching speed to measure the elongation of the test article when it breaks. The bonding strength between layers is expressed in N / mm, and the bonding strength of each layer of a test article of a predetermined size. This value affects the stability of the print quality. In the high-speed state, it is a very important indicator for the surface rubber layer? The top base fabric and the air cushion layer. Others include solvent resistance expressed in mm thickness changes, and ink resistance expressed in mm thickness changes, and each manufacturer has a specified quantity to control. In terms of dynamic properties, the amount of sag is expressed in mm, and the rate of change in perimeter is expressed in%. Each manufacturer also has a prescribed quantity value to control.
