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.

Effects of finger marks on image quality of storage digital laser films;

Major factors affecting the spectral sensitization efficiency of red-sensitizing dye for making laser film are discussed in this paper on the basis of some series of experimental data and years' practical experience.

Currently,mainstream medical dry films mostly include:xerothermic raster display laser imaging films、direct hot imaging films、whole digital sunlight dry films.
