OptiTopo - Measuring the surface of paper and board

The surface of paper and board is extremely important in terms of printing results. By measuring the surface and filtering this in an appropriate way, printing results can often be predicted very accurately.

Many of our customers have found that air-leak instruments such as PPS and Bendtsen do not achieve this sufficiently well. We use OptiTopo, an extremely fast method which, as well as measurement values, also provides valuable images and illustrates the appearance of the surface.

The method can provide answers to questions such as the following:

  • What are the properties of the optimal paper/board surface for printing?
  • How has the topography of the paper been affected by calendering?
  • Are the edge rolls smooth enough?
