Résumé : |
An advanced study of the use of instrument-resolved radiachromic radiometry to solve some of the difficulties presented by traditional radiometry in 3-D processing, roll-to-roll printing and coating, and ink jet printing. Elements of responsivity, dynamic range, and adaptability of various types of films are discussed. Commercially available films and experimental films are studied. Methods of correlation to produce a numerical measure of UV exposure are presented. These methods can be applied easily to laboratory characterization of materials and to production quality control. The principal purpose is to explore the use of standard instruments to quantify the response of radiachromic films in terms of transmission or reflection densitometry. This allows correlation of their optical density to instrument radiometry for (1) process design optimization and/or (2) periodic measurements to verify lamp condition over time. The most important conclusion is that, when carefully designed and used, radiachromic films can be a useful extension of – but not a substitute for – instrument radiometry. |
