Direct smoothness measurement, error analysis and platen inspection

InfiniteFocus in paper and print industry

InfiniteFocus directly measures paper smoothness in 3D. Measures for enhancing printability are thus numerically evaluable. Measurement results in true color information enable an easy, quick and transparent error analysis of print images. In the print industry InfiniteFocus is used for cup measurement on platens.

Optimize measures for surface finishing

  • determine the paper’s homogeneity and establish a correlation between smoothness and printability
  • measure paper topography directly, area based and in 3D via roughness measurement
  • verify smoothness with topographic parameters
  • evaluate measures for increasing paper’s smoothness such as calendaring on a numerical basis
  • obtain all results across large measurement areas and with registered color information
  • measure steep flanks of e.g. fibers in high resolution
  • measure coated and uncoated paper as well as tissue quickly, directly and area based in 3D

Quick and easy analysis of poor printing results

  • verify errors such as the “speckle effect” or missing dots
  • visualize results of the error analysis via true color information quickly and effortlessly
  • detect height variations by measuring the surface profile and make sure the paper shows the necessary homogeneity for a satisfying printing result
  • automatically measure user-defined measurement fields

Measure platens also in production

  • measure form and roughness of cups on platens in high resolution
  • achieve repeatable and traceable measurements even of the cup geometry’s steep flanks
  • perform mobile and therefore flexible surface measurement of the laser structured engraved platen also in production
  • increase process reliability by changing the objective with a nosepiece

3d micro-coordinate measurement technique for roughness and form measurement

Alicona offers optical 3d surface measurement systems for quality assurance in research and production. Core competence is the measurement of roughness and form also across large measurement areas and volumes. The cutting edge measurement and the measurement of small radii and angles are typical applications. Focus-Variation, the core technique of the InfiniteFocus line, combines the traditional surface metrology and the micro coordinate measurement technology. This technology achieves traceable and repeatable results in highest resolution even in production.
