Note on Media Environment: 50% humidity and 72 degrees Fahrenheit is the optimal
conditions for both storage and use of label stock. Store label stock in protective plastic
wrappings. Rewrap partially used stock. Do not store stock directly on concrete floors.
Label stock should be conditioned in this environment for 72 hours prior to use.
Failure to store media in these conditions may result in media tension problems. Too much
humidity will cause labels to curl on the edges.
