Evidence
"It should be noted that the inks were applied to Whatman paper, which has no sizing or impregnation and can therefore absorb the ink well."
Remarks
The paper substrate lacks sizing or impregnation, which leads to deep absorption of inks and can interfere with surface-sensitive analytical techniques like Raman spectroscopy due to lower ink concentrations on the surface (p. 7, 8). FTIR reflectance spectra are heavily dominated by cellulose signals, hindering the detection of minor ink components (p. 8, 19).
