DSS - Dimension Stability System

Modular Measuring System for the Investigation of the Dimension Stability of Paper / Board / Foils in Contact with Temperature or Liquids

DSS with wet stretch module

DSS with heat shrinkage module

  • DSS with Heat Shrinkage Module: Prediction of the converting properties of paper/board/foils concerning the dimension stability at thermal load up to 230°C
  • DSS with Wet Stretch Module: Measurement of the dynamics of the change in dimension of paper by means of one-sided contact with water based liquids under adjustable tension
  • Main applications:
    • Decor paper, gypsum board, flatness of corrugated board, coating base paper, newsprint paper, offset printing paper,
      label paper, ink jet paper, kraft liner etc in contact with:
      • water
      • fountain solution
      • ink jet ink
      • melamine resin
      • gravure ink
    • Runnability at professional laser printing machines and copy machines
    • Register
      • four color laser printing
      • offset printing
      • rotogravure printing
    • Fluting tendency with LWC papers
    • Staple problems at professional offset-, copy and laser printing paper
  • Special applications:
    • plastic foils,
    • pre-impregnates,
    • wall papers,
    • filter paper


  • Modular measuring unit with modules to measure the wet stretch/heat shrinkage
