Color monitoring is one of the methods used for following degradation on varnish applied on paintings. Collecting colorimetric data for monitoring purposes is done effectively, rapidly, inexpensively and non-invasively. In general, colorimetric data are easy to record and read, but the variables associated with them are not always given due consideration. Starting from a specific case study, the panel painting 'Resurrection of Christ and Saints' (1568) by Giorgio Vasari in the basilica of Santa Maria Novella in Florence (Italy), an attempt was made to define a working methodology while providing suggestions for proper planning for monitoring and evaluating the acquired data. The colorimetric data were acquired using a Konica-Minolta model CM-700d colorimeter. The methodology accuracy and repeatability was assured by evaluating the repositioning operations of the instrument on the area of measurements over time, also keeping in mind possible errors induced by operators.

Abstract
Color monitoring is one of the methods used for following degradation on varnish applied on paintings. Collecting colorimetric data for monitoring purposes is done effectively, rapidly, inexpensively and non-invasively. In general, colorimetric data are easy to record and read, but the variables associated with them are not always given due consideration. Starting from a specific case study, the panel painting 'Resurrection of Christ and Saints' (1568) by Giorgio Vasari in the basilica of Santa Maria Novella in Florence (Italy), an attempt was made to define a working methodology while providing suggestions for proper planning for monitoring and evaluating the acquired data. The colorimetric data were acquired using a Konica-Minolta model CM-700d colorimeter. The methodology accuracy and repeatability was assured by evaluating the repositioning operations of the instrument on the area of measurements over time, also keeping in mind possible errors induced by operators.File | Dimensione | Formato | |
