George Kokkinos has written: 'Design of a rig to hold and bring in contact the pressure plate and the driven disk of a clutchsystem in order to measure the pressure distribution across the surface of the pressure plate'
The pressure of the plate or blanket as it comes in contact with paper.
clutch pedal over -centre spring pressure
Anything that touches something else puts pressure on the point of contact. In some cases, such as tapping a finger on paper or a gyroscope spinning on a flat surface, that pressure is light enough to be negligible.

there is a difference between the types of plate movement and a difference in the distance from the Earth's surface.
The clutch will have to be replaced. The pressure plate could possibly be resurfaced but usually it is as cost effective to replace the pressure plate.
Alevel metal plate attached to the tank shell or bottom and located directly under the gauging reference point to provide a fixed contact surface from which liquid depth measurement can be made.
You can measure defects on a plate with a 3-D surface map. To mention defects on a plate in a report you would want to include the shape, surface roughness, and surface finish of the plate.
Pressure is force per area, so P = F/A where pressure is P, force is F and A is area. So Pressure is directly proportional to the force exerted on a surface. So increasing a force by a factor of 2, say, increases the pressure on the surface by 2 also.
