Conservation Measures for Media Art According to Technological Changes: Color Reproducibility Comparison for Conservation of Artwork Using Video Display

Artworks using display devices require conservation treatment due to aging or discontinuation of media. However, irreversible conservation treatment methods such as modification and change of existing media may be included, which may infringe on the right to secure the originality and maintain the identity of the work. Accordingly, a comparative study on the theoretical background and color reproduction elements was conducted to provide basic data for mid to long-term conservation to confirm the possibility of replacing works using discontinued CRT with LCD. Video art is a modern art form that uses video technology as an artistic expression medium and has technology dependence. Therefore, as the conversion of the used medium is appropriate, the materials added in the conservation process are seen as part of securing the originality in terms of ‘material conservation’. An experiment was conducted to compare the color characteristics of CRT and LCD. As a result of the experiment, it was confirmed that the luminance and chromaticity stability of LCD was relatively excellent through the measurement results of spectral distribution, chromatic change difference, background dependence, and time stability, confirming the possibility of alternative application.
