Ageing and dating of blue ball tip inks on paper using in-situ visible spectroscopy and chemometrics

This dataset was collected by Georgina Sauzier and Jasmine McGann at Curtin University from 2014-2017, as described in the linked article. Blue ball tip inks on paper were analysed by diffuse reflectance visible spectroscopy under various office conditions over 32 months. Chemometric data analysis was then used to characterise the ink ageing, and to construct predictive models for dating purposes.

Chemometric analysis was carried out using Unscrambler X v10.3
