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

• Prediction of the converting properties of paper/board/foils concerning the dimension stability at thermal load up to 230°C
• 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:
  • Coating base paper, decor 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
