Conservation framing, explained without the jargon
Acid-free, lignin-free, reversible. What the terms mean, and when they're worth paying for.
By SmartFrames Studio
Conservation framing is a set of choices with one shared goal: nothing done to the piece today should be impossible to undo tomorrow, and no material touching it should damage it over time.
Standard wood-pulp matboard contains acid and lignin. Over years both leach into whatever they touch, burning a visible brown line into the artwork along the bevel. Conservation board is treated to remove them, which is why we flag it separately rather than treating it as an upsell.
Reversibility is the other half. Hinges are made with materials that release cleanly, so the piece can be remounted or sold later without a trace of the framing it once sat in. Anything permanent — dry mounting especially — forecloses those options.
Is it always necessary? No. For a poster you will replace in two years, standard materials are a reasonable choice. For anything original, signed, or irreplaceable, it is the whole point.
