An impression sheet assembly is proposed to enable the pressure exerted on a plane to be determined accurately in a simple manner. This assembly comprises a transparent sheet (1) which is located on the outside and on which the pressure of varying magnitude has to be exerted. The transparent sheet (1) is provided with an adhesive layer (2) on the inside. A component (4) which releases dye and when put under pressure enters into a reaction with the adhesive layer (2) of the transparent sheet (1) is arranged beneath said adhesive layer (2). There is a carrier sheet (6) beneath the dye-releasing component (4). After the image of the pressure distribution has been produced on the adhesive layer (2) and the dye-releasing component (4) has been removed, the adhesive layer (2) is joined to the carrier sheet (6). By providing the carrier sheet (6) with a grid pattern (7) or the like, it is possible, with the aid of a comparison with, for example, a calibration chart (11), accurately to determine the pressure in a specific position from the coloration.
