Abstract:
Objective To research the structure,imaging mechanism and quality of dry view laser imaging film. Methods We extracted 60 pieces of dry view laser imaging film,wet view laser imaging film and ordinary film respectively. Each tape of films was divided into 3 groups in 100 pieces each. They were observed in the same temperature and humidity. Results Group A was observed after 300 minutes,the dry view laser films image of 10 pieces without package,4 pieces packed with plastic and 1 piece packed with paper changed. After 120 minutes,group B was observed; the dry view laser imaging film in different packing had the different changes. To the contrast,the wet laser imaging film's images didn't change in the same humidity and temperature after 420 minutes test. Conclusion The imaging of dry laser imaging film with different temperature,humidity and package will easily affect the image quality.
