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 innventia.com will be one of several websites within RISE. Please visit ri.se for more information about RISE.

Simulation of print and Paper Optics

We have developed tools (methods and softwares) that help our customers' understanding of the complex processes that govern qualities of print and paper. These understandings are also helpful for designing experimental investigations and for interpretation of the observed results. 

Modeling and simulation are important complements to experimental measurements. We have the following tools,

  • Tool of printing dynamics and ink-paper interaction can provide you with a full insight into the complex processes of ink-transfer and ink-drying.
  • Grace is an optical simulation tool for paper and board. With this tool, all physical interactions between light and paper can be simulated on a micro-structure level.    
  • Modeling of Colour reproduction provides you with possibilities to quantitatively evaluate the impact of various factors on the Colour of a print.
