Additional Manufacturer Narrative

KODAK RECEIVED THE SCREEN AND CASSETTE FOR EVALUATION. OUR EVALUATION INCLUDED CREATING AND PRINTING FLAT FIELD IMAGES AND A PHYSICAL EXAMINATION OF THE SCREEN. THE FLAT FIELD IMAGES WERE PRINTED AT AN EXTREME CONTRAST IN ORDER TO EHANCE ANY IMAGE ARTIFACTS. THE FLAT FIELD IMAGES SHOWED ARTIFACTS THAT WAS CLASSIFIED AS MOTTLE. THE PHYSICAL EXAMINATION DID NOT SHOW ANY PHYSICAL DAMAGE TO THE SCREEN. ARTIFACT INVESTIGATION CONDUCTED BY KODAK HAVE SHOWN THAT MOTTLE ARTIFACTS IS CAUSED WHEN A SCREEN IS RE-INSERTED INTO A CASSETTE NOT FULLY DRY. THE CLEANING SOLUTION IS THEN ABSORBED BY THE PROTECTIVE FOAM AND, IN CONTACT WITH THE SCREEN SURFACE, WILL CAUSE AN ARTIFACT. THE AFFECTED CR SCREEN WAS REMOVED AND REPLACED WITH A NEW CR SCREEN.
