The RISE institutes Innventia, SP and Swedish ICT have merged in order to become a stronger research and innovation partner for businesses and society.
During 2017 will be one of several websites within RISE. Please visit for more information about RISE.

Paper and board surface

We have tools for characterising paper and board surfaces!

  • Which are the preferred properties of paper/board surfaces for printing?
  • How has the topography of the paper been affected by calendering?
  • Are the edge rolls smooth enough?

The surface of paper and board is extremely important in terms of printing results. By analysing the surface topography in an appropriate way, the printing results can often be predicted. Properties other than topography that may be important include compressibility and absorption properties.

OptiTopo – a fast, unique method for correlation between paper surface and print defects. *


OptiTopo Expert unit - add-on to the L&W OptiTopo *


Beskrivning: MicroProf.jpg


FRT MicroProf – uses chromatic aberration to calculate height variation at high resolution.


Print Simulation Tester – simulates the printing nip by compressing the paper and measuring the non-contact spots.


Cockling/Waviness – measure large-scale height variations on non-printed and printed paper products.


Print-through – measurement both on average and as local variations. *


MicroDAT – measures the absorption of micro drops on a paper surface.


Measure cracks in coating/ink layer after folding or creasing. *



Measure paper surface and compressibility using confocal microscopy.


Understand which surface defects cause missing dots using confocal microscopy (CLSM).


Coating layer thickness variations with burn-out technique.


Measure the micro surface roughness of the paper surface with CLSM (µm) and AFM (nm).

*) The method is also available for sale
