Storing and Displaying Works on Paper

Why Works on Paper Deserve Care

Prints, drawings, watercolours, maps and vintage photographs are among the most rewarding things to collect. They are comparatively affordable, they sit comfortably in a modest home, and they reward close looking — a good etching changes as the light moves across it. Paper, though, is a fragile medium. It reacts to light, damp, heat, insects and the chemistry of whatever it is touching, and it does so slowly enough that the damage is often only obvious years later.

The reassuring news is that most of that damage is avoidable. A sensible outlay on archival materials, plus a little discipline about where things hang, will add decades to the life of a collection and protect the value of what you own.

What Actually Harms Paper

Four agents do the bulk of the damage, and they tend to work together:

• Light. Ultraviolet and visible light fade pigments and dyes and yellow the paper itself. Watercolours, hand-coloured prints, colour lithographs and most photographs are especially vulnerable. Damage is cumulative and irreversible — there is no way to put colour back.
• Pests. Silverfish, booklice, carpet beetle larvae and clothes moth larvae graze on paper fibres, starch paste and old glues, leaving lacy edges, tiny holes and gritty frass.
• Acid and pollutants. Inferior mount board, wooden backing panels, rubber bands, self-adhesive tape and newspaper clippings all release acids that migrate into paper. The result is foxing — those small rusty-brown speckles — along with staining and brittle, darkened edges.
• Moisture and heat. Damp encourages mould and accelerates foxing; very dry air makes paper brittle; constant swings in humidity cause cockling and, eventually, cracks in the image layer.

To that list add people. Oily fingers, a carelessly stacked pile and enthusiastic dusting with a household cloth have ruined plenty of good prints.

Archival Storage at Home

Aim for a stable, dark, dust-free place at roughly 18–21°C and 45–55% relative humidity, off the floor and away from outside walls. In practice, that means an interior cupboard or a shelving unit in a spare room — not the loft, the cellar, the garage or the airing cupboard.

• Use lignin-free, acid-free boxes with tight lids; buffered board suits most papers, though protein-based photographs prefer unbuffered.
• Store each work in its own acid-free folder or paper sleeve, or in a polyester sleeve if you want to handle it often without touching the surface.
• Interleave with acid-free tissue where works share a folder, and never let them rub against one another.
• Store flat wherever possible. If a piece is too large, roll it around a wide-diameter tube with interleaving, image side outwards, and never roll tightly.
• Remove all tape, staples, rubber bands and newspaper — or, better, ask a conservator to do it.

Mounting, Matting and Hinging

A proper mount is not decoration; it is engineering. Museum-quality board — 100% cotton rag, or at least conservation grade — separates the artwork from the glazing, allows air to circulate and gives the eye room to rest. As a rule of thumb, allow a border of at least 5–8 cm, slightly wider at the bottom.

Hinge from the top edge only, using Japanese tissue and wheat starch paste, or photo corners for photographs. Two small hinges let the paper expand and contract with the seasons; a fully glued sheet cannot, and will cockle or tear. Never trim a sheet, never dry-mount, and never write on the artwork itself — pencil a note on the back of the mount instead.

Framing, Glazing and Display

Good glazing blocks 98–99% of ultraviolet light. Acrylic is lighter and safer in a busy house; glass resists scratching better. Whichever you choose, make sure the artwork never touches it — contact traps condensation and invites mould. Use an archival backing board, a barrier layer between the artwork and any wooden frame, and seal the back to keep dust and insects out.

For display, think in terms of lighting. Around 50 lux is the usual guidance for works on paper, which means no direct sunlight and no uncompromising halogen spotlights. Warm-white LEDs angled across the surface reveal texture without cooking the sheet. Avoid kitchens, bathrooms, sunny hallways and the space directly above a radiator.

Finally, rotate. Keep only part of the collection on show and bring out the rest every three to six months, storing the outgoing pieces in their boxes. It is good for the paper and unexpectedly good for the eye.

Handling, Housekeeping and When to Ask for Help

Wash and dry your hands before handling — clean bare hands are better than cotton gloves, which reduce dexterity. Lift works by the edges, support them from underneath with both hands, and deal with one item at a time on a clear table. Dust frames with a soft dry cloth, keep storage areas clean, and inspect your collection twice a year for the warning signs: fresh specks of frass, tiny holes, brown spotting, ripples or a faint musty smell.

If you find mould, active foxing or old adhesive, resist the temptation to improvise. Household remedies and art erasers cause more loss than they prevent. An accredited paper conservator can often stabilise a troubled sheet for far less than owners expect — and considerably less than the cost of losing it.
