Preserving Colour Copies

Fading Due to Exposure to Light
As with all printed material and photographs, this is not a problem if the copies are stored under normal
conditions. Colour copies exposed for two years to the fluorescent lighting used in general offices will
hardly fade, depending on the storage conditions. Colour copies should be stored in binders or in
locations that are not exposed to light if they are to be kept for a long period of time.
Use of Clear Covers
Do not use PVC type transparent covers. If copies are stored in such covers, toner on the copies
softens, causing the copies and covers to adhere to each other.
Use of Adhesives
Only adhesives that do not dissolve toner should be used for mounting copies; solvents dissolve toner.
Be sure to check the ingredients of the adhesive before you use it. Test some adhesives with an
unwanted colour copy before you use it with a valuable copy.
Inserting Copies Between Printed Pages
When copies are included in books, the solvents contained in printing ink may cause the toner to soften.
The printed pages should, therefore, be thoroughly dried to evaporate any solvents before the copies are
inserted.

Folding Copies

Colour copies differ from black-and-white copies in that toners of four colours are used. These toners are
deposited on the surface of the paper in a layer considerably thicker than black-and-white copies, and
they may peel if the copy is folded or wrinkled. Copies should be stored in flat transparent covers, in
binders, or carefully rolled.
Effect of High Temperatures
If copies are left in high-temperature areas (near heaters, stoves, etc.), the toner will melt, and the
colours will mix.
