TL;DR — Glare is what makes a framed print look cheap in a bright room, and it has two cures: anti-reflective (‘museum’) glass, and placement that keeps the frame from facing a window or downlight. But good framing does more than kill reflections — the mat, the mounting and the glazing together decide whether a print stays flat, clean and unfaded for decades. This guide covers both the look and the conservation, because in a working bar or restaurant they are the same problem.

Framing is conservation, not just decoration
A frame has two jobs: to present the print and to protect it. In a home that distinction rarely matters; in a bar, restaurant or salon — warm, humid, sometimes greasy, often brightly lit — it matters a great deal. The same choices that make a print look expensive (good glass, an acid-free mat, proper mounting) are also the ones that keep it from reflecting, cockling or yellowing. Treat framing as conservation and the good looks follow.
Glass: reflections and UV
Ordinary picture glass mirrors the room — a window, a spotlight, a bright back-bar bounce straight off it and hide the poster. Anti-reflective or ‘museum’ glass carries a fine optical coating that scatters those reflections, so the image reads cleanly from any angle. It costs more, and under bar lighting it is the single biggest upgrade you can make.
Many museum glasses also filter ultraviolet light, which is the main driver of fading in works on paper. If a piece hangs near daylight or under strong LED or halogen light, UV-filtering glazing measurably slows colour loss. If museum glass is out of budget, matte non-glare acrylic is a lighter, cheaper compromise — slightly less crisp, but far better than plain glass opposite a window.
The mat: acid-free and spacing
A mat board is the border between the artwork and the glass, and it does real work. It holds the paper a few millimetres off the glass, so that if condensation forms — common in humid rooms — the print does not stick to the inside of the glazing. And, if it is acid-free (cotton rag or alpha-cellulose), it will not brown the edges of the print over time the way cheap card does. A mat is not just a decorative margin; it is a spacer and a chemical buffer.
Mounting: hinges, never glue
The print should be held in place with hinges of reversible, acid-free tape at the top edge only, so it can hang naturally and be removed later without damage. Never dry-mount or glue a print you care about to a backing board — it is irreversible and it traps the paper against materials that may not be stable. Reversible mounting is the standard conservators use, and it costs no more.
Placement and light
Even perfect glass cannot fix a bad position. Hang the frame so it does not directly face a window or sit under a downlight aimed at its surface; light should rake across the wall, not bounce off the glass into the room. If you want to light the piece deliberately, use a picture light or wall-washer angled from above rather than a spotlight pointed at the glazing — the goal is even light on the paper with no hot reflection.
Bars and kitchens: humidity and grease
A working hospitality room is a hard environment for paper: steam, temperature swings, airborne grease. A sealed frame — backing board taped to the frame edge — keeps dust and grease out, while the acid-free mat manages the occasional condensation. In a very humid spot, avoid hanging directly above a dishwasher station or a steam source, and check the piece once a year for any sign of cockling. These are small habits, and they are the difference between a print that still looks new in ten years and one that quietly deteriorates.

Frequently asked questions
Is museum glass worth the cost?
In a bar or restaurant with bright or window light, yes — anti-reflective, UV-filtering glass is the biggest single improvement to a framed poster, both for looks and for slowing fade.
Glass or acrylic?
Glass is crisper and scratch-resistant; acrylic is lighter and safer for very large frames. Both come in anti-reflective and UV-filtering grades.
Why an acid-free mat?
It holds the print off the glass to prevent condensation sticking, and it will not brown the edges over time the way ordinary card does.
How should the print be mounted?
With reversible acid-free hinges at the top edge — never glued or dry-mounted — so it can be removed later without damage.
