Tests on base-papers and on finished papers

ANALYSES

  • Structure: formation, basis weight, fibre orientation, thickness, etc.
  • Optical properties: brightness, CIE whiteness, gloss, opacity, fluorescence, etc.
  • Surface properties: roughness, Topo 3D, Scanning Electron Microscope (SEM), surface energy, microgloss
  • Electrical and electrostatic properties
  • Permeability and air and liquid absorption
  • Mechanical properties
  • Abrasion resistance
  • Ageing resistance: dry and humid heat, cold, light
  • Suitability and use trials for compliance with “NF” and “NF Environment” standards
  • Durability of papers
  • Coating: optimization of coating colours
  • Characterization of coating colours: rheology, visco-elasticity, surface tension
  • Calendering
  • Printability trials with laboratory and industrial inks
  • Printing quality: set-off, backtrap mottling, mottling, toner adhesion, heliotest, ink transfer, etc.
  • Binding and spiral binding resistance
  • Dusting
