The best way to keep most prints, drawings, and watercolors is mounted in conservation-quality materials or placed individually in acid-free paper folders and protected from light and dirt. Plastic sleeves are not suitable, but translucent acid-free tissue paper is good for interleaving or wrapping small items. Boxes, folders, and portfolios, which are all obtainable and fabricated from conservation quality materials, must rest horizontally in drawers or on shelves.
When handling the work of art, you should touch the paper as little as possible and keep your fingers away from the image. You could consider keeping them permanently framed Contemporary prints should not be handled directly either because their immaculate paper is easily marked with skin oil and moisture. Keep them in a mount or acid-free paper folder.
Protect framed prints, drawings, and watercolors from daylight. Particularly avoid south facing light and try not to hang them directly against the interior of the outside wall of a building: the comparatively low temperature can cause condensation and mold growth inside a frame.
