©Eastman Kodak Company, 2008 October 2008 TI2605 Visual Uniformity Test Procedures INTRODUCTION Reasons to Perform Uniformity Test Uniformity testing is necessary when: • Projection and/or telecine visual inspection of images indicates there may be an unacceptable severity level of non-uniformity (color or density variations) on the origination or KODAK VISION Color Intermediate Film (VCI) footage. • A chemical or mechanical change (or adjustment) has been made within the developer tank, the developer turbulation system, or the bleach and/or fix solutions. Tools Required Uniformity Test Procedure 1. Receive Uniformity Test Kit (precision-flashed test footage, processed check film, documentation describing uniformity imperfections and severity ratings). 2. Before making any mechanical, chemical or design changes to equipment, run ONE precision-flashed test unit through the processing machine. 3. View the processed uniformity test footage using telecine equipment. Telecine should be adjusted according to Telecine Analysis Film (TAF) setup protocol. 4. Printing and projecting the tested footage is another acceptable method for uniformity evaluation. If printed footage is desired, print the origination or intermediate test footage to a neutral density onto KODAK VISION Color Print Film (VCP) (approximately 1.0 density, RGB). 5. Use the specific image descriptors to accurately compare the visual uniformity of the test footage. Note: HELPFUL HINT—Use the uniformity imperfection definitions, and uniformity definitions provided in this document.
