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 IMAGE SHOWED ARTIFACTS THAT WERE CLASSIFIED AS FINGERPRINT ARTIFACTS. THESE WERE LOCATED AT THE EDGES AND CORNERS OF THE IMAGE. THE PHYSICAL EXAMINATION SHOWED AN AREA WITH A SMALL ABRASION AT THE BOTTOM OF THE SCREEN. IN THE FLAT FIELD IMAGE THIS LOOKED LIKE A FOREIGN BODY. THE FINGERPRINT ARTIFACTS HAVE BEEN SEEN ON OTHER CR IMAGES AND ARE ASSOCIATED WITH HANDLING OF THE SCREENS BY BARE HANDS. MANY LOTIONS AND WATERLESS HAND CLEANERS CONTAIN CHEMICALS THAT CAN DAMAGE PHOSPHOR SCREENS. THE AFFECTED CR SCREEN WAS REMOVED AND REPLACED WITH A NEW CR SCREEN.
