Their flat-bed scanner produced works by capturing a series of images using different wavelength light sources from infrared to ultraviolet. A computer program then combines them to emphasise the specific colour light absorbed by the faded ink in order to make it appear more clearly. It could be used to analyse altered or counterfeit documents such as forged passports, bank notes or forensic evidence.
