Patent ID: 8654349

Claim:
Method for determining a topography under load of the surface of a material for one or more printing processes, wherein a test piece of the material intended to be determined is subjected to a compression with a predetermined load between a first and a second clamping surface, after which, in a compressed state, registration is carried out by at least one representation being made of surface portions of the material that are squeezed between and in contact with said first and second clamping surfaces, and that the representation is evaluated, the steps of said method comprising: controlling the compression between said first and said second clamping surfaces in respect of its speed for obtaining said predetermined load and for simulating the true conditions a test piece is exposed to in said one or more printing processes, and synchronizing the registration such that said at least one representation is made at a chosen point in time or chosen points in time during a period when compression of the test piece prevails, wherein the compression is made through movement of one of the clamping surfaces being arranged on a movable compression body, and wherein said predetermined load is set to be between 1 MPa and 20 MPa.
