Press-O-Film provides a simple way to obtain an impression of a
surface for analysis. It consists of a layer of crushable plastic micro
foam affixed to a 50.8 µm (2 mils) incompressible polyester film. When
compressed against a surface, the foam collapses and acquires an
accurate impression, or reverse replica, of the surface.
Several grades of replica tape are available:
Tape Grade
Coarse (C)
X-Coarse (XC)
Optical Grade
Coarse (C)
Optical Grade
X-Coarse (XC)
If only the maximum peak-to-valley height is needed, then
conventional Coarse or X-Coarse can be used. Placing the
compressed tape (replica) into the PosiTector RTR-3D gives a
measure of the average maximum peak-to-valley height (H) of the
surface roughness profile. The Gage automatically subtracts the
thickness of the polyester substrate from all measurements. Press-
O-Film is available in Coarse (C) and X-Coarse (XC) grades to
accommodate measurements in different profile ranges.
Optical Grade Press-O-Film Replica Tape for 2D/3D Measurements:
When measuring 2D and 3D parameters, it is recommended to use
optical grade Press-O-Film. Optical grade tape provides higher
resolution images than conventional Press-O-Film replica tape. It is
available in both Coarse (C) and X-Coarse (XC). Choose the tape
grade that most closely matches the intended maximum peak to
valley height of the surface being measured.
