Cantu established an equivalence between natural and induced aging of a Fisher black ball-point ink written on Nashua photocopy paper (6).

Then, after complete stirring, 4u L of the strong solvent extract was spotted adjacent to the weak solvent spots on the TLC plate.

Canto reported an excellent summary and discussion of all techniques reported to date on the aging of ink (11).

Although the use of accelerated aging to estimate the age of inks has been widely reported, only a limited amount of actual experimental data has been published.

Aginsky measures the extraction of ink solvent (vehicle) components into solvents.

For all the inks tested to date, these measurements detect changes in ink up to 6 – 12 months.
