What is ISO 18941 about ?
ISO 18941 describes the equipment, methods, and procedures for generating a known ozone exposure and the subsequent measurement and quantification of the amount of change produced within both digitally printed hardcopy images and traditional analog photographic color print images due to that exposure.
The test method described in ISO 18941 uses increased levels of ozone to achieve an accelerated test. If the principal “gas fading” mechanism for a system is not ozone, this method might not be suitable and might give misleading results as to resistance of the test image to polluted air.
