Abstract

A specialised spectral multichannel device was built in the view of characterisation of paper manuscripts (codices). It is based on a spectrophotometric module with a concave diffraction grating and a CCD detector. The tests on the manuscripts were performed by measuring the reflectance in a 45/0o geometry. The measured spectral data were used for the calculation of the color parameters in the CIELAB space. The device was tested for applications in conservation-restoration at the National Centre for Conservation and Restoration of Historical Publications within The National Union Museum from Alba Iulia (Romania) by using a Romanian manuscript dating from the 18th century..
