Product appearance and visual branding are important drivers for consumer purchase decisions, as they underpin perceptions of ‘quality’ and ‘desirability’. The project aims to advance primary metrology in spectrophotometry to meet industrial needs for the quantitative measurement of appearance. This will be accomplished by i) defining new spectrophotometric quantities, ii) taking previously ignored corrections terms into account, and iii) developing new traceable spectrophotometric primary references which will provide new tools for quality control and more realistic solutions for virtual prototyping, and will benefit different industrial sectors e.g. automotive, paper, cosmetic and 3D-printing.
This is a joint research project carried out in the framework of the European Metrology Programme for Innovation and Research (EMPIR) (see:http://www.euramet.org/research-innovation/empir/). The EMPIR initiative is co-funded by the European Unions's Horizon 2020 research and innovation programme and the participating states. METAS is one of the project partners in the project.
The overall objective of the project is to define new traceable spectrophotometric references and advanced measurements that allow the characterisation of the visual appearance of surfaces.
The specific objectives of the project are:
