Store your paper in a cool dry place - Paper is a living, natural material and its properties may change slightly with variations in humidity and temperature. All paper likes stable conditions and when stored at room temperature in normal humidity, it stays in perfect condition for a long time - and ready to use.
Don't expose your paper to heat - Do not store next to a radiator or in direct sunlight. Paper's copying and printing properties are affected not only by excessive humidity but also by excessive dryness.
Always store paper flat, in its own packaging - Boxes and ream wrappings have been designed specifically to protect the paper against moisture, dirt and damage during transportation and storage. Keep the paper in its own package - even if it is not full - until it is used. This will ensure excellent print results every time.
Packaging protects the paper - The polyethylene seal on ream wrappers offers many benefits. Dirt or plastic particles cannot get on to the surface of the paper, whilst inside the wrapping, and static electricity is unable to build up across the surface of the paper.
Paper needs time to adjust to the surrounding temperature and humidity - Problems can be avoided when using paper if the pallets of paper stored elsewhere, possibly in the cold, are allowed to adjust to a new room temperature and humidity before use.
The time it takes a full pallet of paper to adjust to a new environment depends on the difference in temperature between the store-room and the new surroundings.
