Abstract
The effect of laser radiation on a German geographic map printed in 1846 is investigated. The sample is irradiated with pulsed and continuous wave radiation (cw) at a wavelength of 532 nm and fluences of 5 and 3 kJ/cm2, respectively. A visible decrease in discoloration resulting from the pulsed irradiation is demonstrated. ATR FTIR and fluorescence spectroscopy are used for diagnostics. The discolouration of the laser irradiated map after five years and the corresponding spectral changes are discussed.
Zusammenfassung
Auswirkungen der Laserstrahlung auf Drucke aus dem 19. Jahrhundert
Die Auswirkung von Laserstrahlung bei der Reinigung einer 1846 in Deutschland gedruckten Landkarte wird vorgestellt. Die Karte wurde gepulst und kontinuierlich mit einer Wellenlange von 530 nm mit einer Dosis von 5 und kJ/cm² bestrahlt. Dabei konnte die Verfarbung des Objektes reduziert werden. Die Folgen der Strahlungseinwirkung auf das Material wurden mit FTIR im ATR-Modus untersucht. Es wurde beobachtet, dass innerhalb von funf Jahren nach der Laserbestrahlung eine Wiederverfarbung des Objektes eintritt, deren Ursachen diskutiert werden.
Résumé
Influence de la radiation laser sur du papier datant du 19eme Siecle
L’article a pour objectif de presenter l’effet d’une radiation laser sur une carte geograpique allemande imprimee en 1846. L’echantillon a ete irradie par rayonnement pulse et par rayonnement continu de longueur d’onde de 532 nm et une densite de flux de 5 et 3 kJ/cm² respectivement. On a pu demontrer une nette reduction de la decoloration de la carte a l’aide de l’irradiation impulsionnelle. L’echantillon a ete egalement passe au diagnostic de la spectroscopie ATR FTIR et de la spectroscopie fluorescente. On a pu observer que dans un intervalle de cinq annees apres l’irradiation au laser une nouvelle decoloration de l’objet a lieu dont on discutera des causes.
