- Raw dat file: Raw data of diffuse reflectance measurements of all ink samples. The spectra were registered from 200 to 2500 nm with a resolution of 0.1 nm (600 nm min-1 scan speed). Each ink sample column gives the reflectance data measured (R %) at each registered wavelength. SIMCA file: Information and data used for chemometric analysis. All the spectra registered were smoothed (1:50) and transformed to absorbance. Each column gives the absorbance measured at each registered wavelength for each ink sample. Accelerated aging time of each ink sample is expressed in logarithmic function. This information was treated with SIMCA software in order to carry out the chemometric analysis.
