Paper Abstract
The reflectance of Spanish manuscripts (paper and ink) dating from the XV to XIX centuries has been studied in the spectral range 350-1000 nm, specially when poor definition and/or manuscript degradation are present. The results have been applied to optimize the readability of the corresponding digital images of manuscript by choosing appropriately the spectral distribution of the source and the spectral sensitivity of the detector in a given digitizing device. For those manuscripts with severe degradation, the method gives enhanced original digital images that could be further processed resulting in optimal final images.
